- Abstract:
- A technique for intrinsic and extrinsic calibration of a laser stripe sensor (LSS) integrated in a coordinate measurement arm (CMA) is presented in this paper. By means of a single calibration object, a one-step calibration method to obtain both intrinsic (laser plane, CCD sensor and camera geometry) and extrinsic parameters related to CMA main frame has been developed, allowing the integration of LSS and CMA mathematical models. The results obtained in accuracy and repeatability experimental tests show the suitable performance of this method, as well as a great ease of use and a very low time consumption.
