Pose Estimation

rosrun spheres_localization pose_estimation map_file descriptor_type camera_stream

Visualization

rosrun spheres_localization visualization world_point_cloud map_file camera_stream image_directory

NOTE: Last parameter of visualization may be omitted for a precolored pointcloud

To use a bag file for visualization:

rosbag play bag_file -l -r 0.1
