Hi friends, do anyone have idea to add obstacle avoidance in move_base with kinect/xtion depth information, not just the fake-laser, but with the whole FOV vertical plane.

depthimage_to_laserscan can give you the lowest value over multiple rows, does that help you?

What I want is to use "multiple rows" of fake "laser" for obstacle avoidance. How can I get the values with depthimage_to_laserscan? Cheers!

Use the scan_height parameter

Hi, I can recommend using using the rtabmap_ros/obstacles_detection nodelet to segment floor and obstacles. Then, use the two topics "obstaces" and "ground" published by obstacles_detection as data sources for your obsetacles layer of move_base. Set "obstacles" topic to marking and "gound" to clearing. Works like a treat, I hope this hels!

Please copy the contents of your rgbd_mapping.launch as well as the command line output of the launch process. Regards

you want all the topics and list of nodes?

If you can, yes please. Either attach a text file or post link to where the log file is hosted.
