| 摘 要： | 基于机器视觉的测距系统已成为铁路、公路交通管理系统的研究热点.结合图像的色彩空间的不同特性,进行适当的变换从而实现目标图形的定位及检测.首先利用图像增强的方法将检测出的图像进行边缘增强,并通过基于圆斜率特性的改进圆Hough变换进行图像中目标图形的特征提取,之后根据已检测出的目标物体的边界,利用统计像素点计算面积的方法计算出目标物体的面积,最后依据计算出的目标图形面积的大小实现目标物体的距离测量.

| Abstract: | In recent years the research of the ranging system based on machine vision is popular in highway and railway traffic management system.Combining images of color space conversion the program detects the target delineation,then enhances graphics positioning edge,and extracts the image of the target feature with Hough transform,consequently graphics can be detected under the border of the object pixel that is calculated using statistical method to calculate the area of the object,finally we could calculate,whi... |
