Image preprocessing General workflow Network processing Application window Supported formats Agisoft PhotoScan is an advanced image-based 3D modeling solution aimed at creating professional quality 3D content from still images. 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 продолжение здесь least two photos.

Both image alignment and 3D model reconstruction are fully automated. 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 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 sparse point cloud 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 agisoft photoscan user manual professional edition free usage in external programs. For instance, 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 construction 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. Another stage is building mesh. PhotoScan reconstructs a 3D polygonal mesh representing the object surface based on the dense point cloud. Additionally there is a Point Cloud based method for fast geometry generation based on the sparse point cloud alone. Generally there are two algorithmic methods available in PhotoScan that can be agisoft photoscan user manual professional edition free to 3D mesh generation: Height Field – for planar type surfaces, Arbitrary – for any kind of object.

Having built the mesh, it may be necessary to edit it. Some corrections, such as mesh decimation, removal of detached components, closing of holes agisoft photoscan user manual professional edition free the mesh, etc. For more complex editing you have to engage external 3D editor tools. PhotoScan allows to export mesh, edit it by another software and import it back. After geometry i. Several texturing modes are available in PhotoScan, they are described in the corresponding section of this manual.

Basically, the sequence of actions agisoft photoscan user manual professional edition free above covers most of the data 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 agisoft photoscan user manual professional edition free parameters controlling each step are explained in the corresponding sections of the Chapter посмотреть еще, General workflow.

In some cases, however, additional actions may be required to get the desired results. In some capturing agisoft photoscan user manual professional edition free masking of certain regions узнать больше the photos may be required to exclude them from the calculations.

Application of masks in PhotoScan processing workflow as well as editing options available are. Camera calibration issues are discussed in Chapter 4, Referencing and measurementsthat agisoft photoscan user manual professional edition free describes functionality to reference the results and carry out measurements on the model. While Chapter 6, Automation describes opportunities to save up on manual intervention to the processing workflow, Chapter 7, Network processing presents guidelines on how to organize distributed processing of перейти на страницу 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 intermediate data in a form agisoft photoscan user manual professional edition free project files at any stage of the process. If you are not familiar with the concept of projects, its 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 procedure and basic rules for taking “good” photographs, i. For the information refer to Chapter 2, Capturing agisoft photoscan user manual professional edition free and Chapter 1, Installation. The number of photos that can be processed by PhotoScan depends on the available RAM and reconstruction parameters used. PhotoScan supports accelerated depth maps reconstruction due agisoft photoscan user manual professional edition free the graphics hardware GPU exploiting.

PhotoScan is likely to be able to utilize processing power of any OpenCL enabled device during Dense Point Cloud generation stage, provided that OpenCL drivers for the device are properly installed. However, because of вот ссылка large number of various combinations of video chips, driver versions and operating systems, Agisoft is unable 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 ссылка на страницу 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.

To install PhotoScan on Microsoft Windows simply run the downloaded msi file and follow the instructions. Open the downloaded dmg image and drag PhotoScan application to the desired location on your hard drive.

Unpack the downloaded archive with a program distribution kit to the desired location on your hard drive. Start PhotoScan by running photoscan. Once PhotoScan is downloaded and installed on your computer you can agisoft photoscan user manual professional edition free it either in the Demo mode or in the full function mode. On every start 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 a serial number to confirm the purchase.

The first choice is set 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:. To use PhotoScan in the full function mode you have to purchase it. 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.

Before loading your photographs into PhotoScan you need to take them and select those suitable for 3D model reconstruction. Photographs can be taken by any digital camera both metric and non-metricas long 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 нажмите чтобы перейти lenses. It is recommended to use focal length from agisoft photoscan user manual professional edition free to 80 mm interval in 35mm equivalent. If a data set was captured with fish-eye lens, appropriate camera sensor type should be selected in PhotoScan Camera Calibration settings prior увидеть больше processing. If zoom lenses are used – focal length should be set either to maximal or to minimal value during the entire shooting session for more stable results.

So do not crop or geometrically transform, i. 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 of light from camera fields of view. Avoid using flash. Alternatively, you could place a ruler within the shooting area. In some cases it might be very difficult or even impossible to build a correct 3D model from a set of pictures.

A short list of typical reasons for photographs unsuitability is given below. 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 agisoft photoscan user manual professional edition free. Photometric modifications do not affect reconstruction results. In this case PhotoScan assumes that focal length in 35 mm equivalent equals to 50 mm and tries to align the photos in accordance with this assumption. If на этой странице correct focal length value differs significantly from 50 mm, the alignment can give incorrect results or even fail.

In such cases it читать больше 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. The distortion of the lenses being 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 it is required to choose proper camera type in Camera Calibration dialog prior to processing. 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 successive chapters. Before starting a project 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 PhotoScan log file to be shared with agisoft photoscan user manual professional edition free Agisoft support team in case you face any problems during the processing.

Here you can also change GUI language to the one that is most convenient for 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 to free one physical CPU core per each active GPU for overall control and resource managing tasks.
