Look at depth value while mouse cursor is staying at one point (0:05-0:06). It is floating from 1.65 to 1.68 m.
This is visualization of the point cloud from D435i of my room walls and door. Distance is approx. 3m. Flat surface looks like storm sea.
Is it supposed to be so wavy?
Okay, I went through the video frame by frame and see what you mean about the range of change whilst that mouse is sitting still on that particular point.
The fact that the waves are primarily on flat surfaces such as the walls and doors makes me think that they are being generated by a semi-random pattern of dots being projected onto the room scene by the camera's IR Projector component. This projected pattern can help the camera to read texture detail on flat, low-texture surfaces. The projection can be turned off if you do not want to use it.
The image below is an example of a RealSense user projecting a dot pattern onto flat walls from an external LED-based projector.
May I please also ask whether you are using fluorescent lights such as ceiling strip-lights in the location where the camera is? These can cause disruption to the camera image because the heated gas inside them causes them to flicker at frequencies hard to see with the human eye. If you are currently streaming at 30 FPS, using 60 FPS has helped improve the image for some people, because the FPS is operating closer to the frequency of their particular fluorescent lights. Others who were having problems with their image under fluorescent lights at 60 FPS conversely found that it improved when running at 30 FPS with their particular lights.
