FAQs
What needs to be done after recalibrating the camera’s intrinsic parameters?
When the point cloud quality is poor and the camera intrinsic parameters are re-calibrated using Mech-Eye Viewer, the robot self-correction program must be rerun to generate new drift correction data. After that, a test pick of the target objects should be performed.
What Should Be Done After Reinforcing the Calibration Sphere or Camera?
-
Reinforce the calibration spheres
If the calibration sphere is found to be loose or displaced, the calibration sphere pose is invalid and should be re-collected. Please refer to Looseness Check and Handling for detailed instructions.

Reinforce the camera
If the camera is found to be loose, it must first be secured, and then the calibration sphere poses should be re-collected to generate new drift correction data. After that, a test pick of the target objects should be performed.
Once the “Auto-correct accuracy drift in vision system” feature is deployed, extrinsic parameter calibration must not be performed, as this will disable the drift correction feature.
