Bug Reports / Re: DEM export fails
« on: July 27, 2011, 12:55:23 PM »
Hello Jan,

We are planning pre-release version of PhotoScan 0.8.3 today or tomorrow. We'll ask you to test if new release still crashes on this set, when building sharp geometry.

Hello jan,

If I understand your case right, you are using "Smooth" reconstructing method. In this case geometry is extrapolated up to the borders of bounding box and DEM is built on this extrapolated volume.
If you use "Sharp" reconstructing method there will be no geometry extrapolation as well as no DEM extrapolation.

Hello jan,

Does this problem occurs every time in the last build?

Hello ionut,

We've updated our site recently, so some features are not working yet.

Here are some links on pdf-examples:

PhotoScan Standard:

PhotoScan Professional:


Sorry for inconvenience.

Hello Ian,

Feature detection doesn't depend on color. Using black&white photos for geometry reconstruction usually gives similar results as for color photos, but in some cases quality of black&white reconstruction could be slightly worse.

Hello Ian,
  I run into the same problem a lot, always at 46%.  Sometimes when I run out of memory, there is an error but it usually happens as you describe.
While testing the image set provided by Charles at Arbitrary, High, Smooth parameters we had the same progress bar "jump" from 46% to 82% but due to it was not accompanied by the lack of memory we were able to complete the task. So this progress bar "stop" at 46% does not always mean the memory shortage.
By the way, if you do remember - how many depth stages are there usually when you experience memory shortage?

Hello Andy,

You can disable b/w photos in the Workspace pane and build texture using only enabled photos in chunk (building texture procedure take in account only enabled photos).

Hello jan,

The next PhotoScan Pro update will support Python scripting, so one could include sending email line to the script (on UNIX OS it shouldn't be a problem I guess).
Another notification possibilities are not planned at the moment, but thank you for the suggestion.

Hello Charles,

Thank you for reporting.

We have tested geometry reconstruction with the same parameters (Arbitrary, High, Smooth) on the set of 24 12Mpix images, but have not faced described huge memory consumption. Building geometry process took 3 hours with a memory peak at generating mesh stage about 9 Gb.

If you are not using volume selection option already, we would recommend to set up a reconstruction volume bounding box so that only head of the person is included. This should help to minimize the reconstruction volume and memory consumption should be also lower during processing.

It will be very helpful if you could provide a sample data set so that we could reproduce the problem ourselves.

Hello Matt,

You are right, currently there is no way to select projection while exporting model and it is always saved in local coordinates. Hopefully, it will be fixed in the next PhotoScan update.

Hello Tom,

You understand right, that for alignment procedure PhotoScan uses all photos in chunk (even disabled).
Disabled photos are not taken in account for geometry  and texture reconstruction.

Feature Requests / Re: resume batch.

Hello Andy,

Could you please describe the conditions when PhotoScan crashes after 30-40 chunks processing?
What process is performed (align photos, build geometry) and what OS are you using? How many photos are there in chunks?

Maybe you've noticed something special that mostly leads to crash. It would we very useful information for us to fix this problem.

Hello olihar,

Unfortunately layered texture is not in our near plans of implementation. But we keep this idea in mind. Thank you for the suggestion.

Thanks for clarification, Mike!

is there a PS version for 32 bit OS?
Currently there is no PhotoScan version for 32-bit Ubuntu.

Hello olihar,

In the current version of PhotoScan the texture is stored internally in PNG format (8 bit per color channel).
The export supports most common images file formats - TIFF and PNG as well.

Unfortunately support for 16 bit color depth is not planned for the near future.
