CALIBRATION OF A STATIONARY CAMERA SYSTEM FOR DETECTING THE POSITION OF A MOBILE ROBOT

摘要

The invention relates to a method for calibrating a stationary camera system (1) for detecting the position of a mobile robot (2). The robot (2) can be moved on a surface (3) and has at least one direction-indicating marker (4). The camera system (1) has one or more cameras (5) for at least partly detecting the surface (3) on a respective image plane, and at least one first camera (5) has an inclination sensor for detecting a pitch angle and a rolling angle relative to the perpendicular. The external calibration of one or more cameras (5) is carried out using an internal calibration by determining an imaging function on the basis of the inner calibration of the cameras (5) and using the direction-indicating marker (4), the pitch angle, and the rolling angle. The invention additionally relates to a stationary camera system (1) which has an image processing device that is designed to detect the orientation of a robot (2).
