摘要
地面三维激光扫描技术虽然具有分辨率高、准确度高、效率高等特点,但在应用过程中存在一系列影响三维激光扫描精度的因素。文中详细分析扫描距离、物体表面材质、控制网、标靶测量精度、光斑大小、扫描点间距、点云拼接精度、全反射物质和外界环境等因素对三维激光扫描精度的影响,并提出对以上影响因素的控制方法。
The ground three-dimensional laser scanning technology has the characters of high resolution,high accuracy,high efficiency,etc,but there are series of factors in the application process,which affect the precision of three-dimensional laser scanning.Analysis is made on the influence of scanning distance,material surface,measurement precision of control network and the target,spot size and scanning point spacing,point cloud splicing precision,total reflection material and external environment on precision of three-dimensional laser scanning,and the control methods based on the above factors are proposed.
