hi,

How should OPT8241EVM calibrate camera parameters be set? Such as duty cycle, LED peak power, etc.

Hi Eric,

Calibration parameters for the OPT8241EVM include lens calibration, phase offset correction, etc. Do you mean how do we set these parameters?

Please refer to the section 7.3.8 of the OPT9221 datasheet.

For duty cycle, refer to section 7.3.3.5.

Eric,

I've attached the checkerboard image. Please note that the pattern counts just the inner points of the checkerboard, and the size of this is 10*15

hi，
Thank you for your support.

When the camera is connected to a PC, the vocelviewer prompts "Could not transfer 0 bytes" and the camera is not working properly. What should I do?

Eric,

Was the camera working previously? Or is it the first time you've plugged it in?

Please share the register settings. Under 'parameters' tab of Voxel Viewer, there's an option to save all parameters.

Eric,

Voxel Viewer returns this error whenever the camera does not stream. Please go through other threads in this forum to see if you are able to get a solution.
If you are not able to find a specific solution to your problem, please start a new thread with that subject.

Subhash
