摘要
数字图像的边缘检测在图像分割、模式识别、机器视觉等中有很重要的作用。从70年代到现在发展出了很多种边缘检测的方法,而对于不同的应用环境,不同算法的效果不同。针对高速公路中图像的特点,对几种典型的边缘检测方法的原理和实现方法进行了详细分析和说明,对比分析了各种算法应用在高速公路图像识别中的优劣,并根据高速公路图像识别系统的特点选择了合适的检测算法。
Edge detection plays a great role in the image segmentation and mode recognition, also does it in the machine vision. There have developed various edge detection algorithms since 1970＇s. However different environments will affect the effects of different algorithms. In allusion to the characteristic of the freeway imaging, the article compares some typical algorithms, and analyzes their applications in the freeway charge system. Based on the imaging recognition system of the freeway, proper algorithms are presented.
