• Accuracy Issues with Distance Measurement Using OAK-D-Lite

I am currently using the OAK-D-Lite camera for distance measurement of objects using spatialCoordinates. However, I am experiencing significant discrepancies between the measured values and the actual distances. From checking the calibration data, it appears that everything is set to factory defaults.

Could anyone advise on how to improve the accuracy of distance measurements with this model? Are there specific calibration steps I should follow, or settings that can be adjusted to reduce these discrepancies? Any advice or recommendations would be greatly appreciated.

Thank you!

    i used polynomial regression 3 not 2

      Why do that? We have onboard stereo engine that does the same thing.
      Make sure you get intrinsics for your current resolution, also recheck the undistortion part - all coefficients should be used - we used the brown-conrady model + prism + lens tilt.

        I don’t understand you well. I haven’t use the reprojetionmatrix to calculate the distance. I have used also intrinsics in another code but i still had a significant difference. Could you please provide me with the code with what you exactly mean. Thank you
