Point cloud realsense artefact in the background

Hello,

I used the realsense with the kinect pointcloud techniques, it works but I have weird artefact in the background. the silhouette seems to repeat over and over in the background. As a beginner I’ve tried everything I know to remove it but nothing worked. can someone help me find a solution ?

Thanks

Do you have a screenshot of the problem?

I don’t know if you can see, but it’s in the background. but I think it’s because of the displace TOP.

Yes, you are correct the Displace TOP is introducing this, bypass that TOP and you’ll see it disappear. It makes sense, the Displace TOP ‘displaces’ pixels based on its second input, and in the second input you have 3 or so different shades of grey which is creating these copies of the silhouette. Using 2D operations on 3D point data is fun and can create wild effects, but often introduce artifacts and surprising results.
