depth_image to point cloud
Hello, I want to convert my depth_image to point_cloud, so I use the package "depth_image_proc". The depth_image_proc to point_cloud_xyz needs two infos:
- camera_info (sensor_msgs/CameraInfo)
- image_rect (sensor_msgs/Image)
The Robot that I used published these infos over the topics. My question is, how can I start this conversation with a roslaunch file?
