Research on Measurement Method of Vehi-cle Profile Dimensions and Position Based on Machine Vision
To improve the working safety and sampling accuracy of automatic sampling of the existing robotic arms in the carriage of the transport vehicle,it is necessary to improve the meas-urement accuracy of carriage dimensions.In view of the limitations and low accuracy of the traditional transport vehicle carriage dimension measurement technology,a method of detect-ing the transport vehicle carriage dimensions with lidar is proposed.Through profile scan-ning,point cloud processing and point cloud clustering,the transport vehicle's point cloud is segmented into front end and carriage,the spe-cific point cloud obtained after segmentation is calculated in real-time to output the required dimensional parameters,and the accuracy and reliability of the system are verified on a real vehicle.The research results show that the use of lidar can effectively improve the measure-ment accuracy of the transport vehicle carriage dimensions and has a positive significance for automatic sampling of goods in the carriage by using the robotic arms.
