基于激光扫描的体积测量系统

Volume Measurement System Based on Laser Scanning

本文基于激光扫描仪设计了一套体积测量系统,用于物流行业测量货物的体积.系统由二维激光雷达、伺服电机、电机控制单元、数据采集与处理单元及其他机械装置组成;数据采集与处理单元运用了离散积分运算处理三维点云信息,进行物体体积计算;多媒体定时器的应用使得数据采集、数据处理和命令响应能够协调运行.实验表明,该系统在距离物体摆放平面5至6 m的位置,以约0.5 m/s的速度完成对被测物体体积的扫描,整体误差可以控制在5%以下.该系统适用性强,可以测量扫描区域中所有物体的体积,具有广泛的应用前景.

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.
