摘　　要：针对目前工业用螺栓孔空间位置检测难度大、精度低等问题,提出了一种基于空间位置点云坐标的检测方法。通过三维激光扫描仪扫描带有24孔的构件,获取所有数据点并进行拟合,构建螺栓孔的位置点云坐标值,对螺栓位置点云坐标进行计算和转换,从而判断螺栓的安装位置。通过构件点云的扫描试验发现,坐标值的平均误差仅为0.4 mm左右。该检测方法能很好的实现螺栓孔空间位置的检测,具备一定的市场推广价值。Aiming at the difficulty of detecting the spatial position of bolt holes in industrial use and the low precision,a detection method based on spatial position point cloud coordinates is proposed.The three-dimensional scanning laser scans the member with 24 holes,acquires all the data points and fits them,constructs the position point cloud coordinate value of the bolt hole,calculates and converts the point cloud coordinates of the bolt position,and judges the installation position of the bolt.Through the scanning test of the point cloud of the component,it can be found that the average error of the coordinate value is only about 0.4 mm.The method can achieve the detection of the spatial position of the bolt hole and has certain marketing value.
