摘　　要：激光扫描测距仪以飞思卡尔MK60DN512ZVLQ10微控制器为处理及控制的核心单元,通过CMOS图像传感器对线状激光在物体上形成截面反射进行实时捕捉采集图像,利用DMA快速储存方式存储图像,并对图像进行分析处理获得激光的坐标,再结合舵机旋转扫描获得多列数据,最终将数据转化为各点的三维坐标,由此获得扫描物体或场景的三维点云数据并实现三维模型重建。该设计方案可靠,成本低廉,同时拥有良好的测量精度。Laser scanning rangefinder uses Freescale MK60DN512ZVLQ10 microcontroller as the core unit of processing, the linear laser by CMOS image sensor in real-time capture cross section is formed on the object reflection to collect images. It use t）MA fast storage memory to store image, and analyzes the image processing to obtain the coordinates of the laser, coupled with the steering gear rotating scanning multicol- umn data obtained. It eventually converts data into three-dimensional coordinates of each point at scanning the object or scene three-dimension- al point cloud data, and realizes the 3D model reconstruction. The design is reliable, low cost, and has good measuring precision.
