Error resilient sensor system for determining a spatial relationship between installation components under harsh environmental conditions

摘要

The arrangement (106) has a marker device (112) that is connected with a drill head (102) of a tunnel drilling machine (100). A camera (114) is connected with a gripper plate (104). The electromagnetic radiation produced at the marker device vicinity (110) is detected. A determination unit (118) is provided for determining the spatial relationship between the drill head and the gripper plate based on the detected electromagnetic radiation and the predetermined geometric data. An independent claim is included for industrial apparatus.
