Bug 4514: LiDAR - Grouping depth maps crash

Hi RC Team,

It imports and aligns the 50 scan positions perfectly. But when it comes to reconstruction it fails, mainly during the grouping Depth Maps segment. I’ve tried to clear and move the cache folder, it does not help. Could you please help to solve this? Is this a HW or SW issue?

P.S.: I was able to mesh extremely small segments (1 scan position, or a couple of m^2 worth of points).

Hi Gabor Bodo

Hard to say if its HW or SW issue just form this description.

Please set back the minimal sampling distance back to 0.000000
You can later use SIMPLIFICATION to reduce the point density and etc.

You made the changes before the meshing or just after it started to crash ?

Hi Wishgranter,

The change was made before the meshing started. I’ve changed the minimal samp. dist. to 0.000000, still crashed. However it crashed much later, ate up all physical memory + created ~72 GB committed page file (not the case before), still on 0% of Grouping Depth Maps. Just two cache files were created (266 & 48 KB).

Is this a different thing now? Not enough RAM or something to do with the windows paging?
*EDIT - created a small reconst. region, still crashed within the physical RAM range. (1st image)

Thanks,
Gabor

Hi Wishgranter,

As you can see RC was able to mesh a small portion, but growing the region crashed the process.

Best,
Gabor

Hi Gabor Bodo

Its possible to get the data for inspection ? RCPROJ + LSPs ( have you converted them from E57 or PTX ? what scanner was used and what postprocessing app for creating the scann data ? )

Hi Wishgranter,

Yes, I’ll try to send you a sample data after you’ve managed to get your licensing server back online! Faro scanner was used to capture data, to process it I’ve used Recap Pro and exported as E57 (complete).

Before your licensing services went down, I’ve managed to start the reconstruction process. But instead meshing all parts, RC just completed 1 out of 10. The remaining 9 was 0 vertices.

Hi Gabor Bodo

lic server is back again. We observe issues from Recap regarding compatibility of E57 ( recap not always export proper E57 files)

So if its possible upload the original E57 files so can try check their status and say what can be done to solve this meshing issue.

Hi Wishgranter,

Both the RC project and E57 files were sent to your email.

Thanks for your help!
