Hi all,

I have a new D435 camera and i want to use point cloud data of this camera, but when I run the example code the image of point cloud is very noise and have many black holes.

What's wrong with my D435 camera? Anyone can help me in this problem? Any filter codes available in this situation? (I use camera in indoor environment with fluorescent light)

The image of point cloud is attached below.

Many thanks in advance!

Using depth cameras under fluorescent light can cause more problems than with bulb lighting due to the flicker of these lights that is hard to see with the human eye. Another user with such lighting had noise problems.

Also, looking at your video, the strength of the lighting (indicated by the apparent shadows behind the objects on the trolley and what seem to be spots where light may be reflecting off shiny surfaces, such as on the bottle and the trolley surface) could be an issue.

In regard to filter settings for the D435, please see the Visual Presets documentation.
