自动瞄准系统中直线测量方法的研究与改进

Research and Improvement of Linear Measurement Method for Automatic Aiming System

设计了一套图像式自动瞄准系统。采用的瞄准方法综合使用了图像处理方法、亚像素细分方法、曲线拟合方法和“电子准星”技术。研究和改进了直线瞄准的方法,直线的定位精度可以达到0.1像素间距,并且可以测量任意位置的直线。对实际的直线边缘工件进行测量,取得了满意的效果。瞄准方法的设计也适用于测量其他类型的边缘。

A set of image automatic aiming system is designed. In the automatic aiming method, image processing, sub-pixel division, curve fitting and ＂electronic front sight＂ technologies are synthetically utilized. The method of linear aiming is researched and improved, by which, the positioning accuracy can be reached to 0.1 pixel interval and straight line in any position can be measured. The practical parts with linear edge are measured and the results are satisfied. The design of aiming method also can be used in other types of edges.
