Evaluating the depth resolution of 3D sensors for manufacturing automation applications



Prem Rachakonda, Geraldine S. Cheok, Marek Franaszek, Kamel S. Saidi


The Intelligent Systems Division (ISD) at the National Institute of Standards and Technology (NIST) is performing research to support the development of documentary standards within ASTM E57.23. This subcommittee is addressing the performance evaluation of 3D imaging systems/sensors that are used for manufacturing automation and vision guided robotics. The applications of these systems extend to other areas such as robotic bin picking, autonomous vehicles, 3D reconstruction and entertainment. This paper discusses the activities of one work item (WK73176) that is addressing the evaluation of the spatial resolution of the 3D imaging system. The key contributions of this paper include the multiple methods to determine resolution of a 3D imaging system.
