基于彩色空间转换与Hough变换的直线检测

摘要

According to the image in HSV color space,hue and saturation characteristics of shadow in the channel and non shadow region are obviously different,the use of HSV color space transform two times continuously,can distinguish between effec?tive shadow and non shadow region in image.Hough transform is widely used in the fields of computer vision,image processing,pat?tern recognition;The advantage of Hough transform to detect the straight line is the robustness of the test results.So This article uses the combination of the two methods of the algorithm to detect the line in the image,and the corresponding experiment results show that this algorithm can not only detect the complex background of the situation,but also can improve the accuracy of detection.%根据图像在HSV色彩空间中,阴影在色度和饱和度通道中都与非阴影区域有明显的区别的特性.利用连续两次的HSV彩色空间变换,可以在图像中有效地区分出阴影与非阴影区域.Hough变换被广泛地应用于计算机视觉、图像处理、模式识别等领域.利用Hough变换来检测直线,其突出优点是鲁棒性较好.所以论文采用这两种方法相结合的算法对图像中的直线进行检测,并做了相应的实验,结果表明这种算法不仅可以检测背景比较复杂的情况,还可以提高检测的准确性.
