Abstract

The existing two-dimensional (2D) vision-based bolt loosening measurement range is generally limited to 0–60°. To overcome this limitation, a bolt loosening angle measurement method along full range of screw exposure length based on three-dimensional (3D) point cloud is proposed. Initially, 3D point clouds of bolt groups were reconstructed using 2D images under 18 working conditions, and the 3D point cloud of a single bolt was extracted from the bolt group. Subsequently, the bolt loosening angle along full range of screw exposure length was measured by calculating the rotation angle derived from the change in screw exposure length before and after loosening. The average relative error of all bolt loosening angle measurement results under the 18 working conditions was 3.46 %. Finally, the factors influencing the proposed method were analyzed. The results demonstrated that the proposed method could accurately measure the bolt loosening angle along full range of screw exposure length.

基于三维点云，在螺钉暴露长度的全范围内测量螺栓松动角度

现有的基于视觉的二维（2D）螺栓松动测量范围一般仅限于 0-60°。为了克服这一限制，我们提出了一种基于三维（3D）点云的螺栓松动角度测量方法。首先，在 18 种工作条件下使用二维图像重建螺栓组的三维点云，然后从螺栓组中提取单个螺栓的三维点云。随后，通过计算松动前后螺钉暴露长度变化得出的旋转角度，测量了螺钉暴露长度全范围内的螺栓松动角度。在 18 种工作条件下，所有螺栓松动角测量结果的平均相对误差为 3.46%。最后，分析了影响拟议方法的因素。结果表明，所提出的方法可以准确测量整个螺钉暴露长度范围内的螺栓松动角。
