Troubleshooting Photo alignment succeeds, but the resulting camera positions appear to be wrong Reconstructed geometry appears to be cut and some important parts are missing The photos included in the project file can’t be opened and operations from the Workflow menu fail iii. Based on the latest multi-view 3D reconstruction technology, it operates with arbitrary images and is efficient in both controlled and uncontrolled conditions.

Photos can be taken from any position, providing that the object to be reconstructed is visible on at least two photos. Both image alignment and 3D model reconstruction are fully automated.

How it works Generally the final goal of photographs processing by PhotoScan is to build a textured 3D model. The procedure of photographs processing and 3D model construction comprises three main stages. The first stage is photographs alignment. At this stage PhotoScan searches for common points on photographs and matches them, as well as it finds the position of the camera for each picture and refines camera calibration parameters. As a result a sparse point cloud and a set of camera positions are formed.

The point cloud represents the results of agisoft photoscan user manual professional edition version 1.2 free alignment and will not be directly used in the further 3D model construction procedure except for the point cloud based reconstruction method. However it can be exported for further usage in external programs.

For instance, the point cloud model can be used in a 3D editor as a reference. On the contrary the set of camera positions is required for further 3D model construction by PhotoScan. The страница stage is building geometry. Based on the estimated camera positions and pictures themselves a 3D polygon mesh, representing the object surface, is build by PhotoScan. Additionally there is a Point Cloud based method for fast geometry generation based on the sparse point cloud alone.

Having built the mesh, it may be necessary to edit it. Some corrections, such as mesh decimation, removal of detached components, closing of holes in the mesh, etc.

For more complex editing you have to engage external 3D editor tools. PhotoScan allows to export the mesh, edit it by another software and import it back. After the geometry i. Several texturing modes are available in PhotoScan, they are described in the corresponding section of this manual. About the manual Basically, the sequence of axtions described above covers most of the model processing needs. All these operations are carried out automatically according to the parameters set by user.

Instructions on how to get through these operations and descriptions of the parameters controlling each step are explained in the corresponding sections of adobe captivate 9 portable download free download Chapter 3, General workflow. In some cases, however, additional actions may be required to get the desired results. For instance, pictures taken using uncommon lenses such as fish-eyes may require preliminary calibration of optical system parameters.

In some по этой ссылке scenarios masking of certain regions of the photos may be required to exclude them from the calculations. Having built up a model you can set a reference system for it and carry out typical meaurements such as calculating the surface area and volume of the model.

All these advanced functions are described нажмите для продолжения the Chapter 4, Advanced use. PhotoScan allows to export obtained results and save intermediate data in a form of project files at any stage of the process.

If you are not familiar with the concept of projects, its brief description is given at hard logic pro free download end of the Chapter 3, General workflow. In the manual you can also find instructions on the PhotoScan installation procedure and basic rules for taking “good” photographs, i.

NVidia GeForce 8xxx series and later. PhotoScan allegedly is able to utilize processing power of any OpenCL enabled device, provided that OpenCL drivers for the device are properly installed. However, due to the large number of various combinations of video chips, driver versions and operating systems, we are agisoft photoscan user manual professional edition version 1.2 free to test and guarantee PhotoScan’s compatibility with every device and on every platform.

The table below lists currently supported devices on Windows platform only. We will pay particular attention to possible problems with PhotoScan running on these devices. Start PhotoScan by running photoscan. Restrictions of the Demo mode Once PhotoScan is downloaded and installed on your computer you can run it either in the Demo mode or in the full function mode.

At every run until you enter a serial number it will show a registration box offering two options: 1 use PhotoScan in the Demo mode or 2 enter the serial number to confirm the purchase. The first choice is agisoft photoscan user manual professional edition version 1.2 free by default, so if you are still exploring PhotoScan click the Continue button and PhotoScan will start in the Demo mode. The employment of PhotoScan in the Demo mode is not time limited.

Several functions, however, are not available in the Demo mode. These functions are the following: saving the project; exporting reconstruction results you agisoft photoscan user manual professional edition version 1.2 free only view a 3D model on the screen.

On purchasing you will get the serial number to enter into the registration box on starting PhotoScan. Once the serial number is entered the registration box will not appear again and you will get full access to all functions of the program. Photographs can be taken by any standard digital camera, as long as you follow some specific capturing guidelines. This section explains the general principles of taking and selecting pictures that provide the most drive viewer free download for windows data for 3D model generation.

Basic rules Use a digital camera with reasonably high resolution 5 MPix or more. Wide angle lenses suit better for reconstructing spatial relations between objects than windows startup safe mode ones.

Avoid not textured and flat objects or scenes. Avoid shiny and transparent objects. Avoid unwanted foregrounds and moving objects as much as possible. Shoot shiny objects under a cloudy sky. Shoot pictures of the scene with a lot of overlap. Capture most important scene content from multiple viewpoints 3 or more.

Do not crop or geometrically transform the images. More photos is better than not enough. Spending some time planning your shot might be very useful. If you intend to set a reference coordinate system for reconstructed 3D model, make sure to identify or place on ground markers that will be used to set reference coordinate system and scale. Measure reference distance. Make sure to study the following schemes and read the list of restrictions before you get out for shooting photographs.

Capturing scenarios The following figures represent several typical capturing scenarios: 4. A short list of typical reasons for photographs unsuitability is given below.

Modifications of photographs PhotoScan can process only unmodified photos as they were taken by a digital photo camera. Processing the photos which were manually cropped or geometrically warped is likely to fail or produce highly inaccurate results. Photometric modifications do not affect reconstruction results. In this case PhotoScan assumes that the 35mm focal length equivalent equals to 50 mm and tries to align the photos in accordance with this assumption.

If the correct focal length value differs significantly from 50 mm, the alignment can give manual microsoft publisher 2016 free download results or even fail.

In such cases it is required to specify initial camera calibration manually. The details of necessary EXIF tags and instructions for manual setting of the calibration parameters are given in the Camera calibration section Lens distortion The distortion of the lens being used to capture the photos agisoft photoscan user manual professional edition version 1.2 free be well modeled using the Brown’s distortion model.

Otherwise it is almost impossible to build a precise 3D model. Fish eyes and ultrawide angle lenses are poorly modeled by the distortion model implemented, which leads to inaccurate reconstructions. If you are using PhotoScan in the full function not the Demo mode, intermediate results of the image processing can be saved at any stage in the form of project files and can be used later.

The concept of projects and project files is briefly explained in the Saving intermediate results section. The list above represents all the necessary steps involved in the construction of a textured 3D model from your photos. Some additional tools, which you may find to be useful, are described in the Chapter 4, Advanced use. Loading photos Before starting any operation it is necessary to point out what photos will be used as a source for 3D reconstruction.

In fact, photographs themselves are not loaded into PhotoScan until they are needed. So, when you “load photos” you only indicate photographs that will be used for further processing. To load a set of photos Select Add Photos In the Add Photos dialog box browse to the folder containing the images and select files to be processed.

Then click Open button. Selected photos will appear on the Workspace pane. Photos in any other format agisoft photoscan user manual professional edition version 1.2 free not be shown in the Add Photos dialog box. To work with such photos you will need to convert them in one of the supported formats.

If you have loaded some unwanted photos, you can easily remove them at any moment. To remove unwanted photos On the Workspace pane select the photos to be removed. Remove Items toolbar button. The selected photos will be removed from the Inspecting the loaded photos Loaded photos are displayed on the Workspace pane along with flags reflecting their status.

The following flags can appear next to the photo name: NC Not calibrated Notifies that the EXIF data available is not sufficient to estimate the camera focal length.

In this case PhotoScan assumes that the corresponding photo was taken using 50mm lens 35mm ссылка equivalent. If the actual focal length differs significantly from this value, manual calibration may be required. More details on manual camera calibration can be found in the Camera calibration section. NA Not aligned Notifies that external camera orientation parameters were not estimated for the current agisoft photoscan user manual professional edition version 1.2 free yet.

Images loaded to PhotoScan will not be aligned until you perform the next step – photos alignment. Aligning agisoft photoscan user manual professional edition version 1.2 free Once photos are loaded into PhotoScan, they need to be aligned.

At this stage PhotoScan finds the camera position for each photo and builds a point cloud model.

Photos can be taken продолжить any position, providing that the object to be reconstructed is visible on at least two photos.

Both image alignment and 3D model reconstruction are fully automated. How it works Generally the final goal of photographs processing with PhotoScan is to build a textured 3D model. The procedure of photographs processing and 3D model construction comprises four main stages. The first stage is camera alignment. At this stage PhotoScan searches for common points on photographs and matches them, as well as it agidoft the position of the camera for each picture and refines camera calibration parameters.

As a result bersion sparse point cloud and a set of camera positions are formed. The sparse point versio represents the results of photo alignment and will not be directly used in the further 3D model construction procedure except for the sparse point cloud based reconstruction method.

However it can be exported for further usage in external programs. For editiin, the sparse point cloud model can be used in a 3D editor as a reference. On the contrary, the set of camera positions is required for further 3D model reconstruction by PhotoScan. The next stage is building dense point cloud. Based on the estimated camera positions and pictures themselves a dense point cloud is built by PhotoScan.

Dense point cloud may be edited and classified prior to export or proceeding to 3D mesh model generation. The third stage is building mesh. PhotoScan reconstructs a 3D polygonal mesh representing the ddition surface based on the dense or sparse point cloud according to the user’s choice.

Generally there are two agisoff methods available in PhotoScan that can be applied to 3D mesh generation: Height Field – for planar type источник статьи, Arbitrary – for any kind of object. The mesh having been built, it may be necessary to edit it.

Some corrections, по ссылке as mesh decimation, removal of detached components, closing of holes in the mesh, smoothing, etc.

For more versoin editing you have to engage external 3D editor professionall. PhotoScan allows to export mesh, edit it by another software and import it back. After geometry приведенная ссылка. Several texturing modes are available in PhotoScan, they are described in the corresponding section of this manual, as well as orthomosaic and DEM generation procedures.

Camera calibration issues are discussed in Chapter 4, Referencing, that also describes functionality to optimize camera alignment results and provides guidance on model referencing. Professionall referenced model, be it a mesh or a DEM serves as a ground for measurements.

Area, volume, profile measurement procedures agisoft photoscan user manual professional edition version 1.2 free tackled in Chapter 5, Measurements, which also includes information on vegetation indices calculations. While Chapter 7, Automation мысль adobe acrobat pro dc help free айтой opportunities to save up on manual intervention to the processing workflow, Chapter 8, Network processing presents guidelines on how to organize distributed processing of the imagery data on several nodes.

It can take up quite a long time to reconstruct a 3D model. PhotoScan allows to export obtained results and save agisfot data in a form of project files at any stage of the process. If you are not familiar with the concept of projects, uxer brief description is given at the end of the Chapter 3, General workflow. In the manual you can also find instructions on the PhotoScan installation agisoft photoscan user manual professional edition version 1.2 free and basic rules for taking “good” photographs, i.

For the information refer to Chapter 1, Installation and Chapter 2, Capturing photos. Chapter 1. The number of photos that can be processed by PhotoScan depends on the available RAM and reconstruction parameters used. PhotoScan is gree to be able to utilize processing power of any OpenCL enabled device during Dense Point Cloud proofessional stage, provided that OpenCL drivers for the device are properly installed.

However, because of the large number of various combinations of video chips, driver versions and operating systems, Agisoft is unable suer test and guarantee PhotoScan’s compatibility with every device and on every platform. The table below lists currently supported devices on Windows platform only. We will pay particular attention to possible problems with PhotoScan running on these devices.

Although PhotoScan is supposed to be able to utilize other GPU models and being run under a different operating system, Agisoft does not guarantee that it will work correctly. Start PhotoScan by running photoscan. To use PhotoScan in the full function mode you have to purchase it. On purchasing you will get photoscwn serial number to enter into the registration box on starting PhotoScan.

Once the serial number is entered the registration box will not appear again and you will get full access to all functions of the program. Chapter 2. Capturing photos Before loading your photographs into PhotoScan you need agisoft photoscan user manual professional edition version 1.2 free take them and select those suitable for 3D model reconstruction. Photographs can be taken by any digital camera both metric and non-metricas ;hotoscan as you follow some specific capturing guidelines. This section explains general principles of taking and selecting pictures that provide the most appropriate data for 3D model generation.

Make sure you have studied the following rules and read the list of restrictions before you get out for shooting photographs. The best choice is 50 mm focal length 35 mm film equivalent lenses. It is recommended to use focal length from 20 agisoft photoscan user manual professional edition version 1.2 free 80 mm interval in 35mm equivalent.

If a data set was captured with fisheye lens, appropriate camera sensor type should be selected in PhotoScan Camera Calibration dialog prior to processing. If zoom lenses are used – focal length should be set either to maximal or to minimal value during the entire shooting usre for more stable results. Capturing photos. Capturing scenarios Generally, spending some time planning your shot session might be very useful.

In some cases portrait camera orientation should be used. It is recommended to remove sources aggisoft light from camera fields of view. Avoid phohoscan flash. Alternatively, you could place a ruler within the shooting area. Interior Incorrect Interior Correct. Restrictions In some cases it might be very difficult or even impossible agisoft photoscan user manual professional edition version 1.2 free build a correct 3D model from a set of pictures. A short list of typical reasons for photographs unsuitability is given below.

Modifications of photographs PhotoScan can process only unmodified photos as they were taken by a digital photo camera.

Processing the photos which were manually cropped or geometrically warped is likely to fail or to produce highly inaccurate results. Photometric modifications do not affect reconstruction results. Lens distortion The distortion of the lenses used to capture the photos should be well simulated with the Brown’s distortion model. Otherwise it is most unlikely that processing results will be accurate. Fisheye and ultra-wide angle lenses are poorly modeled by the common distortion model implemented in PhotoScan software, so editipn is required to choose proper camera type in Camera Calibration dialog prior to processing.

Chapter 3. General workflow Processing of images with PhotoScan includes the following main steps:. If you are using PhotoScan in the full function not the Demo mode, intermediate results of the image processing can be saved at any stage in the form of project files and can be used later.

The concept of projects and project files is briefly explained in the Saving intermediate results section. The list above represents all the necessary steps involved in the construction of a textured 3D modelDEM and orthomosaic from your photos.

Some additional tools, agisoft photoscan user manual professional edition version 1.2 free you may find to be useful, are described in the successive chapters. Preferences settings Before starting a abisoft with PhotoScan it is recommended to adjust the program settings for your needs.

In Preferences dialog General Tab available through the Tools menu you can indicate the path to the Manul log file to be shared with the Agisoft support team in case you face any problem during the agisoft photoscan user manual professional edition version 1.2 free.

Here you can also change GUI language to the one that is most agisoft photoscan user manual professional edition version 1.2 free editikn you. PhotoScan exploits GPU processing power that speeds up the process significantly. If you have decided to switch on GPUs for photogrammetric data processing with PhotoScan, it is recommended prrofessional free one physical CPU core per each active GPU for overall control profsssional resource managing tasks.

General workflow. In the Add Photos dialog box browse to photosca folder containing the images and select files to be processed. Then click Open button. Photos in any other format will not be shown in the Add Photos dialog box. To work with such photos you will need to convert them in one ediion the supported formats. To remove unwanted photos 1.

On the Workspace pane agisoft photoscan user manual professional edition version 1.2 free the photos to be removed. Right-click on the selected photos freee choose Remove Items command from the opened context menu, or click Remove Deition toolbar button on the Workspace pane. The photoscxn photos will be removed from the working profrssional. Camera groups If all the photos or a subset of photos were captured from one camera position – camera station, for PhotoScan to process them correctly it is obligatory to move those photos to a camera group and mark the group as Camera Station.

It is important that for all the photos in a Camera Station group distances between camera centers were negligibly small compared to the camera-object photoscaan distance. However, it is possible to export panoramic picture for the data captured http://replace.me/11142.txt only one camera station.
