Abstract:This study designs a volume measurement system based on laser scanner for the logistics industry to measure the volume of goods. The system consists of two-dimensional LiDAR, servo motor, motor control unit, data acquisition and processing unit, and other mechanical devices. The data acquisition and processing unit uses discrete integral operations to process 3D point cloud information and calculate the volume of the object. The application of multimedia timers enables data acquisition, data processing, and command response to work in harmony. The results show that the system’s measurement error can be controlled below 5%, scanning at a speed of about 0.5 m/s and at a position 5 to 6 meters from the plane of the object. The system has strong applicability, which can measure the volume of all objects in the scanning area and has broad application prospects.
