【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。更多还原

【Abstract】 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.更多还原
