@Shivam-Sehgal , I believe the TOF processing settings may have changed between SDK 1.1 and 1.3 (more noise filtering was added).
In both cases, the ground is visible (although hard to see in the black image). In the 1.3.0 case, the other vehicle is not visible in TOF output, but there is less noise.
Are you able to test the two SDK versions with some easy features for TOF sensor to pick up? Some large objects with simple geometry and some small objects.
