摘要
为避免光团跟踪中十字丝标志对被跟踪目标的干扰,通过分析十字丝标志的几何轮廓特性,引用直线臂的概念,将十字丝抽象为两条相交的直线臂,提出了一种基于Canny边缘检测、随机Hough变换的图像去十字丝方法.。该方法不需要准确计算十字丝的位置、宽度信息,通过计算包含直线臂的最小矩形对十字丝进行定位进而采用双线性插值法去除十字丝。通过对大量十字丝图像的实验测试,结果表明,该方法对光团的大小、形状具有鲁棒性,是一种实用、有效、快速的图像去十字丝方法。
To avoid the disturbing of cross during the tracking of light blobs, by means of analyzing the characteristic of cross, a method on fast wiping of cross is proposed which is based on canny edge de- tecting and randomized Hough transform, which regards the cross as two intersected straight line arms. This method uses the minimal rectangle which covers the line-arm to locate the cross that does not need to compute the accurate location and width of cross and wipe out cross by bilinear interpolation. Experi- ments with images show that the algorithm can wipe out cross fast and it is robust to the changing of the light blobs＇ size and shape.
