Accuracy of Distance Measurement
The accuracy of distance(= depth) measurement using a stereo camera depends on many factors
such as image sensor, lens and the distance between the two cameras, i.e., baseline of the stereo
camera. Also, the absolute error grows as the distance to the target objects.
For the oCamS-1CGN-U with the default lens set, the theoretical measurement error is shown as
follows:
