What is the pixel disparity of rtabmap? Want to

I want to estimate the depth accuracy of my stereo camera using this formula:

https://stackoverflow.com/questions/19421003/how-field-of-view-changes-depth-estimation-in-stereo-vision

So if I need to detect at 4 meters I am getting a pixel disparity of 7 pixels. Is that good enough? What can rtabmap offer in this term?

Can you please update your question with the formula that you wish to use? That way, should that link change, this question is still self-contained.

Pixel disparity is unrelated to rtabmap. If you want to follow that formula then you will need to retrieve the intrinsic values of the image sensor of your stereo camera from its datasheet.

  • Baseline
  • Focal length
  • Pixel size
