How to generate depth images with the same parameters as my camera Zed2i ? #1093

Describe the issue

I have this question because getting the grayscale by my camera and generating synthetic ones is different: For my camera the nearest objects is with the pixel value of 255 and for the synthetic images is 0 The depth range i think it would be different because the grayscale is [0,255] and each value represent a diferent value of distance related to the depth range. So how could i define the depth range on blenderproc? Another topic is that the grayscale of the depth image on the zed2i is 16 bit and for the synthetic depth images is 8 bit. How could i change that? Thanks in advance!

Hey @joaoparaujo01,

blenderproc outputs depth/distance values as float values in meters. So you should be able to transform them into any scale you like.

Thanks for the answer. Can you give me a simple example on how i could do that?
