Metashape crashing when generating Tiled model with TLS and drone data

[MichalDV]

Hello,


after initial problems of joining drone data and TLS data, we have successfully generated arbitrary mesh. After this we wanted to generated tiled mesh in the same project, but metashape crashes every time we try to do so. We have tried to disable GPU for this step as suggested on forum, but without success, it crashes again during preprocessing.


we are on windows version of 1.7.5. build 13229 (64 bit)


Log of this event with GPU on is bellow:

Hello MichalDV,

Looks like the problem occurs, when the source images are being read. If the issue is caused by corrupted files, you can try to disable half of the images in the set and try again, if it crashes, repeat with the second half of the dataset.

[MichalDV]

It behaves interesting, When I enable only TLS group it works fine, when I enable only drone group it also works fine. I'm already in contact with support but maybe someone from community have more info on this.

Hello MichalDV,

We have analyzed the issue and it appears that the problem is related to the mixture of different image formats (8-bit and floating point data in your case) in tiled model generation procedure (during the image preprocessing stage in particular). The fix will be included to the next version update.

[MichalDV]

Thank you, in meanwhile I will try to find some temporary workaround.

[Alexey Pasumansky]

Hello MichalDV,

The fix is included to 1.7.6 pre-release version update (build 13315), please let me know, if you manage to process the original data (drone photos + TLS scans) together now:

I was able to finish processing using new version and with low quality settings for sake of time, but texture is all black and white and wierdly blownup.
used settings for processing:

depth maps: quality = Low, depth filtering = Mild, PM version
Tiled Model: source data = Depth maps, pixel size = 0.1, tile size = 512, face count = Low, ghosting filter = 0

[MichalDV]

I've tried processing same dataset again, but it is still crashing later in processing.

First it will throw warning during buildTextureBlock  -  finished #0 BuildTiledModel.buildTextureBlock (8/20): Texture and page data types mismatch

And later it cannot find those texture blocks and fails completely  - 

2021-10-27 13:12:58 Error: Can't open file: The system cannot find the file specified (2): k:/kezmarok_SRC/ruzbachy/laser_forum.files/0/0/tiled_model.5/tex53.dat

Hello MichalDV,

Thank you for the update on the issue, will try to reproduce both problems.

Hi Alexey,

did you have any success reproducing our issues?
