[ros-users] Stereo image to Point cloud

Dear all,

At this moment, we are working with a standard Videre stereo camera and make use of standard nodes available from ROS repositories to publish a dense point cloud (stereo_image_proc: node). It would be of great help if we could have some suggestions on how to correlate a point on a 2D stereo images to a 3D point in a point cloud? Do we need to make a new node to perform this operation? What would be its feasibility, accuracy?

Thanks and Regards,
Debjyoti Bera.
