【Abstract】 An industrial robot localization method based on computer vision is proposed under the condition of a static camera.A monocular vision system is introduced to deduce the localization measurement model by means of a linear camera model.Through the sequence of images,a moving object is tracked with CAMSHIFT algorithm,following detecting according to background difference method in which a modified self-adaptive mixture Gaussian model is adopted as the background updating method,thus localizing them and estimating their motion parameters in order to guide the robot.Experimental results show that the presented method is fast and effective,so it is able to meet the requirement of real-time visual location.更多还原
