摘　　要：为实现仓储粮储量在线实时监测,该研究开发了一种基于三维激光扫描技术的粮食储量在线监测系统。采用自主研制的倒置式粮仓专用型三维激光扫描仪对储粮进行扫描,通过上位机通讯、采集点云数据并控制扫描仪的工作过程,应用粮食体积计算软件实时计算储粮体积和数量,从而解决了仓储粮储量快速高精度监测的问题。使用该系统在中储粮某直属库进行系统验证试验,结果表明,测量得到的粮食体积满足最大误差不超过1%的技术指标,且经过多次试验检验,系统具有较好的稳定性、测量精度高、操作简便等优点,能够满足仓储粮储量监测的要求。该研究为实现仓储粮储量的快速实时在线监测提供了有效的方法。The rapid and accurate monitoring of the grain storage is an important problem to be solved by the national food regulatory authorities. This study developed an on-line monitoring system of grain storage based on the 3-D laser scanning technology to realize the on-line real-time monitoring of grain storage. The system consisted of a hardware system based on a 3-D laser scanner and a point cloud data processing software system. The hardware system mainly completed the function of collecting the 3-D point cloud data of the grain surface, and it consisted of the 3-D laser scanner（GSLS003, Hangzhou, China）, the infrared camera of fixed waterproof lens（CBP-350N5, Upland, USA） and the workstation DELL M6800. The processing software system mainly realized the functions of point cloud data post-processing, data transmission and preservation. The software system comprised of the scanner control software, the grain volume calculation software and the reserved interfaces. In order to solve the problem of the rapid and high precision monitoring of the grain storage, the verification test of this system was carried out in a state-owed granary in Anhui province in February, 2014. In the test, the center of the 3-D laser scanner was fixed on the granary roof. All the instruments of the system were plugged into a power supply. After that, the upper computer could access to the local area network in order to control the whole system. The point cloud data of the grain surface, the grain volume and weight were obtained. The self-developed 3-D laser scanner of upside-down type for grain was used to scan the grain surface to get the point cloud data. Firstly, the scanner was connected by communicating with the upper computer. After that, the scanning parameters were initialized by zero adjustment function and the motor speed was set to start the scanning by the speed control function. Finally the 3-D point cloud data collected by the scanner were transmitted and stored in the terminal workstation. The upper computer was appli
