EXTRINSIC RGB-D CAMERA CALIBRATION FOR LEGGED ROBOTS

Abstract

This paper describes a method to identify the extrinsic parameters of RGB-D cameras mounted on legged robots. Since the calculation of the parameters is based on the detection of the robots feet in the camera images, no special calibration objects are required. Therefore the method is simple to use and can even be applied automatically. Experiments demonstrate the precision and the robustness of the method.
