Abstract: Application of camera calibration toolbox in the Matlab software calibrated the carema's interior and exterior parameters by tra-ditional camera pinhole imaging principle. Find out the connection between the image pixel coordinate system and the world coordinate system. And with the vanishing point in the image,determine the robot moving path. Find out the robot pre-pass area in the image. Based on the edge detection of the obstacles,determine whether it is appeared in the pre-pass area,and conduct monocular vision measurement for the obstacles. Put forward a kind of distance calculation method along the robot moving direction related. Ensure the robot doesn't collide with obstacles.
