I am using simulated Kinect inside V-REP to capture point cloud. I noticed following unwanted behaviors with this Kinect-
- It has detected points on far clipping plane (it is a free space, so there shouldn't be any points)
- The far clipping plane is not exactly plane. instead, it is a curved surface.
Please see a screenshot of the scene. Notice the red colored points detected by Kinect in the figure below-

Why such unwanted behaviors?
The points on a point cloud represent a kind of surface, so there shouldn't be any points on free space. How to stop Kinect to detect points on far clipping plane?
Please note that my goal is to generate a similar point cloud which we can get from the real Kinect sensor.

you are free to modify that behaviour. In the current code, the points that do not detect anything are clipped to a maximum distance from the sensor. You could modify the code to following:
Code: Select all
if u[w+3]<2.5 then
i.e. it will discard points that are farther away than 2.5 meters from the vertical plane the vision sensor lies in.
