Abstract :
This paper describes a method to estimate 3D structure for mobile robot. The vision-based system of the mobile robot includes a monocular CCD camera mounted on it which can find and track the fixed reference points in 3D space while the robot moves freely. In this method a special feature point is always kept at the center of the image as the reference point by visual feedback, and then the rest feature points nearby it could be located to build a local map. In the paper, the method is mainly discussed upon the translational motion and rotational motion of the robot respectively. Experimental results show the validity of this method
