Hi, I am trying to get depth data from L515. I want to know if there is any package that I can use for L515 and how to get depth information from which topic. I am using ROS melodic 18.04 and now using realsense-ros package from github.

    Hi Gkswns519.

     

    You can refer to RealSense ros wiki.

    You should be able to get the depth data from

    • /camera/depth/image_rect_raw

     

    Regards,

    Rizal

    Okay, thanks for your infromation. When I check /camera/depth/image_rect_raw, I only could see the raw data. But I want to get the distance, e.g. the center distance in meter or something. So, how can I convert the raw date to distance and get the real distance?

    Hi Gkswns519,

    A GitHub collaborator has shared a Python script for printing the depth value in mm for ROS in the following discussion.
