Abstract

A two-part method for calibrating a laser high definition profiler is presented. The profiler consists of laser line sources and a video camera, and it is designed to be deployed on a remotely operated vehicle (ROV). In the first part, distortions in the digital image were measured using images of a test grid, and corrected by an interpolation method based on a virtual pinhole camera model. In the second part, the equations of the laser planes were determined according to their intersections with a target of known geometry, whose position and orientation were obtained by a registration process.
