摘要:

为了提高沉头孔垂直度检测精度,实现检测过程自动化,提出一种基于视觉测量的沉头孔垂直度检测方法.该方法通过建立沉头孔平行投影数学计算模型,将三维空间测量问题转换为二维平面测量问题.为减小视觉测量过程中因透视投影产生的计算误差,应用透视几何原理修正计算模型,通过牛顿法求解该模型,分析模型计算精度与窝深、物距之间的关系.最后进行了机器人自动化制孔与视觉测量实验,结果表明,采用该方法所得沉头孔垂直度的平均视觉测量误差约为0.03°.

Abstract:
A new method based on vision measurement was proposed to improve the accuracy and automation of the countersink perpendicularity detection process. Firstly, a mathematics computing model for countersink perpendicularity based on parallel projection was established, which could convert the 3D measurement problem into a 2D problem. Secondly, the perspective geometry theory was applied to correct the calculation model to reduce the error caused by the perspective projection. The Newton iterative algorithm was adopted to solve the nonlinear equation of the calculation model. Finally, the relationship between the algorithm accuracy and the countersink depth as well as the photographic distance was analyzed. A complete experiment was designed for automatical robot-based drilling and vision measurement. Results show that the mean error of the vision-based detection for countersink perpendicularity is about 0.03°with the proposed method.
