Hi, I want to get the depth frame using L515 with Realsense-ROS ( ROS1 ).
So i saved depth frame using 'colorizer' filters. ( Just depth/distance frame data size was so big to communicate my system, so i had to use colorize compression. )
And i need distance, so i tried to decompress referring Cororization Compression Post ( https://dev.intelrealsense.com/docs/depth-image-compression-by-colorization-for-intel-realsense-depth-cameras )
But i think colorized depth frame's data information is relative distance ( from minimum to maximum at that frame ), not absolute distance.
I attatch the example what i want to explain.
Distance in circle : 6.7m
Distance in circle : 8.8m
But the real distance of that circle is about 1.2m.
So, My question is How can i get the absolute distance from colored depth frame?
