Camera Calibration / Re: Точность калибровки
« on: October 18, 2011, 12:12:29 PM »
Здравствуйте, Руслан,

Для увеличения точности калибровки рекомендуется использовать большее число изображений, но при этом следует учитывать, что дисторсия объектива зависит от позиции фокусировки.

Agisoft Lens предназначен для получения приблизительной калибровки, поскольку для более точных калибровок требуются трёхмерные калибровочные объекты.

Bug Reports / Re: settings in batch process module

Hello Klass,

Currently when using Batch process you need to apply changes to dropboxes and editboxes by clicking somewhere away from the dropbox you've made the last changes to.

Please let me know if it doesn't work, but it have to.

Hello Rick,

Could you please send to or attach to your post log file or console output.

General / Re: Texture Export Issue

Hello jknox,

Could you please check you are using "Orthophoto" mapping mode at building texture stage. On the first screenshot it seems like texture was built using "Generic" mapping mode (in this mode the texture is cut into pieces) and it does not look like the model on the second one.
The blurred areas on the texture screenshot are just interpolated areas between texture pieces.

Hello jknox,

Could you please provide additional screenshots containing model view and chunk properties.

Hello Kjellis,

Undefined regions outside the model are saved with large negative values outside of the data range of the valid regions. Normally GIS software should detect this and correctly handle such undefined regions. Does ArcGIS behave differently? Do you have a sample GeoTIFF DEM with partial coverage that is handled properly by ArcGIS so that we can compare the data?

Hello Kjellis,

Turns out I have another problem with the DEM; it shows one value that is -32 767 meters, while all others are correct.
It might be the format incompatibility problem. Could you please answer what format are you using for this DEM?

Hello aliensa,

The problem with the sample data is likely to be caused by wrong volume selection. As I understand in the case shown on your screenshot PhotoScan tries to reconstruct the whole scene including background buildings. If you use bounding box selection tool after the align photos stage and choose only the area that includes statue the result has to become better.

Hello aliensa,

The difference is only in the set of selection tools available. If you like Photoshop tools more you can use them and just import alpha-channel. Or, for example, if PhotoScan tools allows to minimize the time spent on masking you can use PhotoScan.

Hello aliensa,

If you have photos with alpha-channel you can apply it as mask using "Import mask..." command in Photo menu.

Hello Kjellis,

We have checked the coordinates with on-line converter and they seem to be in Africa. Please check you have the correct coordinates. For Norway you should have y-coord be greater by order than x-coord and here you've got inverse situation.

Hello Kjellis,

Could you please provide a screenshot of PhotoScan Ground Contol dialog box with coordinates of markers/cameras and selected geographic coordinate system?

Hello Peter,

Any progress with Python? If there is a problem for you we can help you with script.

Hello Kjellis,

Can you open the same DEM in the ArcGIG Explorer and if so does if appear in the proper area?
Have you experienced similar problems with previous version of PhotoScan?

Feature Requests / Re: Animation mode
« on: October 04, 2011, 03:47:38 PM »
Hello Peter,

Using Python scripting you can automate the following process:

- add photos and split them into chunks,
- import camera calibration,
- add ground control and set the coordinate system,
- align photos in each chunk,
- build geometry in each chunk,
- build texture in each chunk,
- export point cloud/model/texture from each chunk

and some minor features.
