摘要
针对光纤面板暗影的特点,实现了利用自适应Canny算子进行暗影的检测。首先将OTSU算法进行改进,实现拉伸图像灰度级,增强目标与背景的灰度差。然后将改进的OTSU算法在VC++开发环境中嵌入到Canny算子中,实现Canny算子阈值的自适应确定。实验结果表明,改进的自适应Canny算子检测出的暗影边缘减少了伪边缘,排除了毛刺的影响,边缘定位更加准确、清晰。并且在程序上避免了高阈值比例参数的手动设置,很大程度上降低了程序的复杂性。
In this paper, optical fiber panel （OFP） shadow detection was realized by using self- adaptive Canny operator against the characteristics of the shadow. First, this paper improved the OTSU algorithm by tensioning the gray-scale of the image, and enhancing the gray gap of the goal and the background. Then embedded this improved OTSU algorithm in the Canny operator, realized determining the threshold self-adaptively. Experimental results showed that the detected results of this improved self-adaptive Canny operator reduced the pseudo edge, excluded the impact of a number of impurity, edge location were more accurate and clear. And it avoided setting the proportion of high threshold parameter manually, reduced the complexity of the program to a large extent.
