An Image Recognition Method Based on Hough Transform And Geometric Characteistics

本文提出了一种基于霍夫变换和所辨识图形(椭圆/圆)几何特性的图像识别方法。该方法能够比较准确地提取图形(椭圆/圆)的各项几何参数,如形心、椭圆旋转角、长短轴。笔者将此方法应用于基于图像处理的自动报靶系统,取得了比较好的效果,能够满足系统所需要的精度和速度。

This paper presents a method of image recognition which is based on Hough transform and the geometric characteristics of ellipses or circles. We can get the geometrical parameters, such as the feature point, the rotate angle, the major diameter and the minor diameter, of ellipse or circle accurately by using the method. The method was used in an automatic scoring system of shooting games using image processing. The experimental results showed that the method significantly reduced the time and improved the accuracy.
