Drilling normal vector alignment method based on high-reflection imaging principle

The invention belongs to the technical field of optical measurement, and particularly relates to a drilling normal vector alignment method based on a high-reflection imaging principle, which comprisesthe following steps of acquiring an image by adopting a normal vector measurement system, extracting a highlight light spot center point, compensating an inclination angle error, calibrating normal vector perpendicularity and the like. The drilling normal vector alignment method based on the high-reflection imaging principle is non-contact measurement, the influence of curvature on normal vectormeasurement under the condition of large curvature is fully considered, the high-reflection imaging principle is adopted, and large-curvature skin drilling normal vector alignment based on the high-reflection imaging principle is achieved. 本发明属于光学测量技术领域，具体涉及一种基于高反光成像原理的钻孔法矢对准方法，其包括采用法矢测量系统获取图像、高亮光斑中心点提取、倾角误差补偿以及校准法矢垂直度等步骤。本发明提供的基于高反光成像原理的钻孔法矢对准方法为非接触式测量，在充分考虑到大曲率条件下曲率对法矢测量的影响，采用高光反射原理，实现了基于高反光成像原理的大曲率蒙皮钻孔法矢对准。
