Application Of Robot Vision Postioning In Production Line Handling

Vision is one of human feelings,and most of the information that human beings derive is from vision.Like human beings,if we install visual sensors on robots,it can also greatly improve the robot's ability to get information from the outside world.With the improvement of science and technology,robot has been growing rapidly as a comprehensive product of various disciplines and technology,and robot vision plays a more and more important role in the application of robot.In recent years,vision sensors play an important role in robot vision location and environment perception.On the one hand,computer technology and image processing technology have been improved;on the other hand,the positioning principle of laser radar and ultrasonic is to achieve target object ranging through active pulse and receiving reflection pulse.But when multiple robots work together,such sensors can interfere with each other and cause errors.And for some special objects,objects can't be identified well,such as absorbable or transparent obstacles.Therefore,robot localization technology based on vision sensor has become one of the key technologies of robot localization in industrial field.This paper is a study of robot vision positioning.From the application of the production line,the robot is designed to carry monocular camera and laser sensor,and the information fusion obtained by two sensors is used to locate the target product on the production line,so that the robot can locate and grab accurately in the range of precision.It not only improves the intelligence of production line,but also extends the application of robot.This paper mainly discusses the following contents: reviewing the development history,development status,and working principle of robot vision,the overall layout design of the robot vision system based on monocular vision is carried out,In view of the characteristics of the robot vision positioning system A camera calibration method based on the robot's motion space center point of HALCON is proposed to calibrate the visual positioning system.In order to locate the grasping product accurately,a localization method based onmonocular vision and laser fusion is proposed to plan the robot path and guide the robot to select the optimal path.Finally,the feasibility of the monocular vision robot system is proved through the specific implementation.
