Stereo calibration issue with dot pattern

[kedarbhope]

Hello, I would like to appreciate the work and effort involved in developing the DICe code. I come across the issue with the stereo calibration in version 2. After giving necessary inputs to the stereo calibration module. The following error is occuring which stops the calibration. In cal log file there is no error is mentioned, Following are the (1) snapshot of the error. (2) cal log file.

All dots of all input images are clearly detected with adeptive threshold but calibration couldn't move forward here after.

Input images are as follows

Kindly guide me to solve this issue.

Thanks for your help in advance.

It looks like everything worked fine for the _0.jpeg image, but is there anything strange about the _1.jpeg image? It looks like something failed for the right image. (You only show the left debug image above)

[kedarbhope]

Thank you for your prompt response Please find the both camera images as follows Left camera Image Right Camera Image

I also tried with checkboard pattern but it couldnt work and problem persist at same point.

Another attempt were made to see the PC configuration does affect the same. To do so I tried to perform Stereo calibration with version 2 in Window 7 PC and Window 10 PC (64 bit) but it stopped at same point.

It is observed that in preview mode all the dots in both the images are very well identified with auto threshold for all the images (89 nos). please see the following snapshots for few of the images. Iamge 0 Image 6 Image 22 Image 35 Image 65 Image 89

It cab be seen that all the dots are very well identifed in preview mode but it got stopped during calibration after 1st image.

Please look into these and provide solution.

Thanks in advance.

Have you tried this in Version 3.8? That is the latest package installable version of DICe. In particular some work was done between versions 2 and 3.8 to improve the calibration routines for the dot patterns. The updates might have fixed the issue you are running into.

I tried stereo calibration in Version 3.8 in Window 10 (64 bit) PC. Similar input files are used for calibration process . It is observed that no dots are identified in preview mode in any of the images. please see the following debug images in version 3.8 in which no dots are detected. Left camera Image Right Camera Image

I also tried to see the possibility for identification of good dots in similar images which was shared in my previous responses but it couldnt detect those too. Please see the snapshots of the same images. Image 6 Image 22 Image 35 Image 65 Image 89

I addition to these, i also run calibration process and it run up to 89 images and failed as can be see in following image.

Further to check the calibration possibility using check board patterns, good intersections ae detected in preview mode. See the debug images Left camera Image Right camera Image As can be see in following image that good intersections are detected and It is observed for all 89 images.

As we start calibration it fails with following CAL LOG details. --------------------------------------CAL LOG----------------------------------------

It cab be seen that all the interactions are very well identified in preview mode but it got stopped during calibration after 1st image.

I have uploaded 50 numbers of input calibration images for your reference. Images can be downloaded from following link.

Please look into these and provide solution.

Thanks in advance.
