We are currently working with the ZED Mini stereo camera and are looking to improve measurement accuracy for our application.
Could you advise on the recommended calibration procedures (e.g., intrinsic/extrinsic recalibration, depth tuning, or any SDK tools) to achieve higher accuracy? Additionally, are there best practices or guidelines for optimizing depth precision?
Our use case involves close-range (~0.35 m) measurements for a surgical robotics application, where high accuracy is critical.
All the ZED stereo cameras are precisely factory calibrated using robotics arms to provide accurate movements during the procedure.
Every manual procedure that you could perform at home is normally less accurate than our factory calibration.
We recommend performing a manual calibration only if you notice that the camera is not working correctly because it received a strong shock, or because you are working on “not standard” conditions: underwater, behind a distorting glass, etc.
I recommend you read these sections of the documentation for details:
