摘要
在单张成品检测中,Hough算法是一种应用非常广泛的图像角度检测方法,但其具有所需计算容量大、运算速度慢、效率低的弊端。提出了一种基于快速Hough算法的局部检测方法,能有效地减少计算容量,提高运算效率,从而满足工业成品检测时间上的要求。
Hough algorithm is a widely used method in detecting the angle of image. However, it has some disadvantages, such as large memory space, slow speed. This paper proposed a new method based on an improved Hough algorithm, which can effectively reduce the computing time, improve the working efficiency. So it has a good performance in detecting industrial products.
