摘　　要：为解决现有三维激光雷达设备在采集堆场点云数据时无法控制扫描密度和扫描区域的问题,设计了一种与智能化行车相结合的点云数据采集系统。系统使用激光测距模块组成密集阵式高度测量模组配合增量式编码器作为数据采集单元,利用上、下位机通讯技术实现了PLC与PC机之间的数据交换。最终在MATLAB软件中利用所采集的数据成功建立了点云数据模型。经实验验证,系统与智能行车系统协同运行可以实现密度、区域可调节的空间坐标数据采集。To solve the problem that the existing 3D LiDAR equipment cannot control the scanning density and scanning area when collecting point cloud data in stockpiles,this paper designs a point cloud data collection system combined with intelligent cranes.The system uses a laser rangefinder module to form a dense array height measurement module,and an incremental encoder as the data collection unit.The data exchange between PLC and PC is realized through upper and lower computer communication technology.Finally,the point cloud data model is successfully established in MATLAB theoretical software using the collected data.After experimental verification,the system can achieve spatial coordinate data collection with adjustable density and area by coordinating with the intelligent crane system.
