I too would be interested in seeing RGB pointclouds from the OAKD-lite in ROS.
I see this defunct post on the DepthAI github is the about the most recent thing I can find RGB Point Cloud · Issue #10 · luxonis/depthai-ros · GitHub
A few other notes on the topic:
depth_image_proc
package. It doesn’t help that the registration node doesn’t compile (last I checked) but even once you fix that it doesn’t seem to work.I’ve been working on other stuff, but I definitely want to circle back to this at some point as it seems like a pretty fundamental issue.
Hi,
i cloned this specific git commit, but when im launching the simulation with the depth camera or the normal camera xacro file, im not getting any camera topic…
all my topics are:
/clock
/joint_states
/parameter_events
/performance_metrics
/robot_description
/rosout
/tf
/tf_static
but in gazebo, i see the camera image projected into the air infront of the robot.
furthermore i get no errors when launching the sim:

does anybody have a clue, what the problem might be?
thanks alot
Hi! I have a problem.
There are no points (no 3D) in RViz2. I opened “PointCloud2” → Stastus: Ok → Points: Showing [0] points from [0] messages. Please, help to solve this problem. I’ve no idea.(((
I checked rqt_graph. n__rviz doesn’t subscribe on /camera/points topic.
