Scan 3d Invalid Data Value#

The Scan 3d Invalid Data Value is the value which stands for invalid disparity. This value is always 0, which means that disparity values of 0 correspond to invalid measurements.

To distinguish between invalid disparity measurements and disparity measurements of 0 for objects which are infinitely far away, the Stereo ace camera sets the disparity value for the latter to the smallest possible disparity value of 0.0625. This still corresponds to an object distance of several hundred meters.
