uvmap noise?

[Marios_B_]

Hi there!

I tried to get the position of a specific point I found in my image using uvmap so that I can get the aligned depth/color coordinates.

However uvmap returns -1,-1 very often, although the target is just the left-most point of an inner contour of a blob.

What else can I do, to get correctly the position of a specific point I found using depth image on color image?

You have to remember that those two cameras (depth and color) have a different field of view. Also, not all pixels contain depth information.

Depending on your application, you may want to use the information of the neighboring pixels, not exactly the one you are looking at.
