I am having the same issue, I am wondering if you reached any solution?

Hello, I'm using velodyne height map , so far i am struggling to only view the x,y,z coordinates of obstacles. even once I try to edit on heightmap.cpp file nothing changing in output. what could be best way to as to only view the coordinates without the raw data matrix. if anyone can clarify to me what is meant by offset for instance this means that the value of the x is on zero position in the raw data matrix.

thank you

hello, you got any solution, I am facing the same issue

well, i recorded that a bag from VLP-16, which don't record RGB data. will the libraries still work.thank you

yea, that's what I am trying to do.I am new using ROS. so even when I try to update the .cpp file nothing changes in the

Hello,

Regarding Velodyne lidar obstacles detection. I am using the velodyne_height_map. I was seeking to be able to detect the distance between the sensor and the obstacle and the angle at which the obstacle located. by using the publish command I was able to see the format. if you can help me to be able to understand more of the format of the output data packet.

thank you very much, appreciate your support

thank you for your answer, but how could I know from the published topic which ones are the x ,y,and z coordinates. as t
