For example, the topic name of point cloud from RGBD sensor, the camera workspace (in the frame_id of the point cloud image), the grasp approach direction and angle, the grasp boundary (in the frame_id of the robot base). In computing, serialization (US spelling) or serialisation (UK spelling) is the process of translating a data structure or object state into a format that can be stored (for example, in a file or memory data buffer) or transmitted (for example, across a computer network) and reconstructed later (possibly in a different computer environment).
