摘要
基于手持光刀法三维测量具有精度高、速度快的优势,针对此法需多次测量获得完整物体点云数据,提出基于3标签点云拼接算法,分析了3特征点转换算法的数学原理,采用棋盘格标签精确获取了相邻测量的共同特征点,推导了转换矩阵计算方法,提出了拼接精度的检验方法,最后基于标准球和标准平面,检验了算法的应用测量精度。
Based on the advantages of high accuracy and high speed of three-dimensional measurement by hand-held optical knife method,aiming at obtaining complete point cloud data from multiple measurements,a 3-label point cloud registration algorithm is proposed.The mathematical principle of the 3-label point transformation algorithm is analyzed.The common feature points of adjacent measurements are accurately obtained by checkerboard label,and the calculation method of transformation matrix is deduced.A stitching accuracy method is proposed.Finally,based on the standard sphere and the standard plane,the application accuracy of the algorithm is tested.
