  • Depth accuracy of OAK-D pro, OAK-D Pro W

Hello,
I was planning to figure out which model of OAK-D I should go for with regards to getting a depth accuracy of 0.2-0.4mm at a distance of 250mm.
As I am planning to work with depth image. So, I would be glad if you could provide me the model, and depth accuracy for them at 250mm, as it is not been mentioned in the documentation of OAK-Pro and OAK-Pro W, except for in meters of distance.

    Thankyou for you reply
    I checked the once you suggested but it is not depth IR(stereo). OAK-SR is RGB stereo and also I am looking for something which will give me a depth accuracy of 0.2mm- 0.4mm at 250mm. Even if the FOV is greater I can go less distance to grab the better depth accuracy though.

      Hi HarshalShirsath
      Well, the OAK-D pro and W have ideal distance stating at 70cm unless you are lowering the resolution to 400p and enabling extended disparity - but this will make accuracy worse (https://docs.luxonis.com/projects/api/en/latest/tutorials/configuring-stereo-depth/#short-range-stereo-depth). In any case, for accuracy purposes avoid W version since it introduces more lens distortion.

      Thanks,

          Hello jakaskerl
          Thankyou for the support I will look into it as for now it doesn't seem to work with a type of accuracy of 0.2-0.4mm in depth even after getting the distance at 350mm which the minimum distance I can reach (400p) for better accuracy.
          I will do do the calculations as per your mentioned link and get back to you asap.

              HarshalShirsath I'm in a similar boat to you. I'm currently considering OAK-D-SR-POE as an option. It has the closer stereo depth of the standard SR, but with an additional TOF sensor and IR sensor. Allegedly, they are planning on adding alignment of the TOF to the stereo but even without that the IR+Stereo should give much better depth results than the standard SR or Pro series at close ranges.

              I'm still a month or two out from making final purchases for my project, so if you find something that works for you for these close ranges please let me know! If I end up purchasing the SR-POE cameras and no one else has notated it I'll try to post the accuracy numbers at close range
