Abstract
For a monocular camera-based mobile robot system,we propose the active visual method for robot localization,based on the double freedom pan-tilt.First,the kinematic model of the mobile robot system of monocular vision is given.Secondly,by controlling the pitch and yaw angles of pan-tilt,the camera optical axis always points to the target geometry center in order to solve the field of view problem.Coordinate system relative pose solution method which based on dual quaternion avoids calculating the singularity and improves the positioning accuracy of mobile robots.Finally,according to pan-tilts feedback angles,extrinsic parameters of the camera,the pose and the position of the camera,the position vector and pose vector of the mobile robot are obtained.
