Premature end of JPEG file

(1/2) > >>

KBL:
I'm getting the error "premature end of jpeg file" while merging five chunks with an average of about 1000 images in them. I've completed this run successfully with a 1, 2, and 4 GPU configuration, but it's giving me this error while running with 3 out of 4 GPUs enabled. Attached is an image of the recent log

Alexey Pasumansky:
Hello KBL,

Does the issue persist, if you reduce the depth maps reconstruction area with the problematic GPU configuration and re-start the process with the same parameters (according to log the issue appears when the depth maps area calculated, so seems to be a start of the dense cloud reconstruction operation)?

KBL:
I can definitely try that Alexy, if you can clarify exactly what you mean. The setup has been successful with 2 and 4 GPU configurations, but fails in #3, so it is a bit odd. For the depth maps step, I have the parameters set:
- Quality = PhotoScan.LowQuality
- Filter = PhotoScan.ModerateFiltering)
- Cameras = my cameras
- Reuse_depth = <not set>
- Progress = <not set>

Alexey Pasumansky:
Hello KBL,

In case it would be possible to minimize the dataset where the issue occurs, it would be easier to perform further test to identify the source of the problem.

Does the operation stop when the "Premature end of JPG" message appears or the processing continues?

KBL:
The operation hangs with that message.
