Image Grabber - Calibration Fails
Posted: 23 Jul 2020, 11:06
Hi everyone,
New on this forum hoping for some help.
I use the DAVID laser scanner software (version 3.9 I think) It has structured light functions and laser scanning functions.
Since I do a lot of photogrammetry I thought I'd try the image grabber. This function is in both laser scanner and SLS programs.
I've watched the YouTube vid of the lets scan work flow, and I can not get it to calibrate properly.
In the laser scanner program it calibrates but then I don't know how to scan the item?
In the SLS program , the same set of calibration images fail to calibrate.
They load fine and sequence through on screen, but I get a 'can't see enough targets' error - I have tried a number of views which show more targets and less targets and get the same error.
Sometimes it picks up the targets, puts the little green markers in and then fails.
Seems to act differently when you click calibrate at different times of it skipping through the sequence.
Any help would be great, is there some setting somewhere which I need to adjust? I don't know.
It would be interesting to see how nice the results are using this method.
Cheers
