| 摘 要： | 双球冲成形是常用的材料性能实验，其形状复杂，虽然内外为圆形，但不一定是同心圆。为了保证对其定位的准确性和快速性，在硬件定位的基础上，采用重心定位结合改进的Hough算法来实现，即借助先验知识，从参数空间入手，缩小Hough变换参数空间中圆心坐标和半径参数的范围。加快了执行速度，大大减少了内存利用，提高了检测精度，使得系统满足实时检测的需要。

| Abstract: | Double olsen test is commonly used to examine the materials' mechanical properties.Double olsen's shape is quite complex and it is composed of inter and outer circles which have no same center.To precisely and quickly determine its round center,the Hough transform was adopted to obtain sample's contour for determining the sample position in the image base on hardware location.An advanced Hough transform was developed by narrowing the parameter range of radius and center of circle with the help of prior experience.It reduced resource consumption greatly and improved the running speed and precision. |
