@Chad-Sweet Thanks for your reply. This is the exact answer I was looking for. The flight core is perfect but here at our company we need to use different Pixhawk board for some specific application.

@manzur Interesting, thank you for the information! Perhaps I was wrong about the default Network ID, I will take a note of that.

Update:

I have performed the calibration process as you mentioned for both Stereo camera and tracking camera by following the calibration documentation https://docs.modalai.com/calibrate-cameras/ though they are not moved from their original position of VOXL flight deck.

While performing the calibration for stereo cameras I have also fixed the focus for both left and right camera. But after the calibration process the collision prevention does not seem to be working any more.

By that I mean the the obstacle topic does not seems to detect anything even it is very close or far from the wall. I also tried with different object to see if the camera can pick up the difference but it does not seems to be consistent any more.

At 0 degree angle it mostly shows 0 m. It only shows some value while it is in the ground but once flying it is completely 0 m in withing +- 30 deg angle range.

After several try I decided to perform the calibration process again, and after the process I found same result. I also tried to change the CP_dist from QGC parameter ranging from 0.5- 10 meter but it does not seems to work anymore.

Then i realized I have made a big mistake by not saving the default calibration.stereo.xml file for calibration and then I found the sample calibration file in the voxl-camera-calibration git folder which then I replaced it with the calibrated file.

Once this process is complete I then fly the Modal AI m500 and it worked almost as before but the CP_dist value of 1.5 m seems now too much and we reduced it to 0.8 meter.

This the sample calibration.xml snippet from the git hub link:

I also noticed the focal_length_x and y for calibrated camera is ranging from 488-490 for both camera value which is much higher value after the calibration process compared with the sample calibration file shown above.

Please let us know what can be done to correct this calibration problem or at least how I can obtain the default factory calibration data from modal ai.
