General / Re: .obj change coordinate system
« on: June 03, 2014, 05:13:59 PM »
Hello MINE,

To estimate the transformation from one coordinate system to another it is necessary to know coordinates of the same point in both coordinate systems. Coordinates in local system of mesh vertices may be derived from OBJ file, but do you have the coordinate information for corresponding points in UTM?

Hello MINE,

In principle, if you have exact coordinates in UTM of some certain model vertices, it is possible to calculate transformation matrix for coordinate conversion from local coordinates into UTM.

Hello Claude,

If the suggested way with camera import will not work, let us know and will try to create a Python script. If possible, provide the .psz file to support@agisoft.ru (just with aligned camera positions, dense cloud and mesh are not required).

General / Re: Ground Control pane - Error data in red
« on: June 03, 2014, 01:32:49 PM »
Hello,

It has the meaning of highest error (coordinate, angle and reprojection), but you shouldn't pay much attention to it, since in the next update there will not be any red highlights in the Ground Control pane.

General / Re: IMPORT dense point cloud
« on: June 03, 2014, 12:17:21 PM »
Hello MINE,

Dense cloud import currently is not supported.

Importing point cloud file using mesh option will not produce any good results, because PhotoScan will try to use points as mesh vertices, but there are not any faces.

Hello LMG,

Yes it's possible, but would it be reasonable, since the camera orientation angles are not utilized during processing?

Python and Java API / Re: Ground control total error value
« on: June 03, 2014, 08:54:42 AM »
Hello Arthur,

Currently it is not accessible directly, to get this value it is necessary to calculate individual errors at first as a difference between source values and estimated by PhotoScan.

Hello Alexander,

We've received the data and now are investigating the problem.

Hello Claude,

And are these scans referenced and scaled in any coordinate system? In principle it is possible to apply translation vector to the whole scene, but actually it is necessary to know where's "up" and what are the units in the current model scene (or how to convert models' units to cm).

Hello Claude,

If you have the fixed camera rig and the camera labels are the same across every project. You can load all the projects into the single PhotoScan window as chunks, using Append command in File menu and use Camera based chunk alignment.

Feature Requests / Re: Photoscan Professional "Artist" Edition
« on: June 02, 2014, 05:14:23 PM »
Hello all,

It seems that too little difference has left between proposed Artist and current Professional editions for quite a huge gap in price. So currently, at least for the nearest future, we do not see the possibility for releasing the new edition.
However, the functionality of Standard edition may be extended by few minor features.

Hello Claude,

Do you wish to move mesh relatively to camera positions? Or to import mesh from external file and move it relatively to the model generated in active chunk?

General / Re: What causes "Can't build dense cloud"?
« on: June 01, 2014, 01:30:45 PM »
Hello photohokie,

The most likely reasons of "Can't build dense cloud" problem are the following:

- insuffient number of matching points inside the bounding box between every pair of images,
- presence of camera shooting position in the field of view of other cameras,
- camera calibration issues.

Maybe you can provide a screenshot of the sparse cloud and camera positions?

Hello William,

Can you please specify the reconstruction settings used for mesh generation? Please also check that you have been using version 1.0.4 for model reconstruction (in older version there was the problem causing black texture generation for high-poly models: http://www.agisoft.ru/forum/index.php?topic=1883).

Black texture may be a result of too many isolated faces or noise of the surface in case of disabled interpolation.

Hello William,

Actually, orthophoto mapping mode means, that you'll get texture covering only 2D surface, so all the vertical areas will not be properly textured.
In case you'll need to generate texture for all the surfaces, you need to use Generic mode.
