基于Hough变换圆检测技术的客流统计 摘 要 在当代社会中，Hough变换圆检测技术的学习和使用日益广泛，Hough变换的原理是一种用于在边缘增强处理后的图像中,提取边缘特征的有效而又简单的方法，它能用来够提取图形中的直线、圆、椭圆、二次曲线甚至是任意形状的边缘形状进行Hough检测。Hough变换在计算机监视、军事防御、办公自动化等许多领域中都得到了普遍的关注和广泛的应用。 基于Hough变换圆检测技术对一些单位进行客流统计非常有意义，通过对客流量的统计和分析能理性安排计划和合理分配资源，使得运营管理系统更加完善。国内外的一些研究人员已经利用Hough变换技术统计公交系统的载客量,使得公交系统更加趋于完善。 本论文以基础Hough变换圆为基础，在MATLAB软件中进行模拟仿真。首先在MATLAB中建立一个能对视频处理的操作界面，导入一段自上向下拍摄的视频，对视频中的类似圆头型进行判断识别，最后对识别到的类似圆头型进行统计，得出数据。 关键词：Hough变换 客流统计 类似圆 MATLAB仿真 Based on Hough transform circle detection technology of traffic statisticszy Abstract In modern society, the Hough transform circle to learn and apply the increasingly widespread. Hough transform is used in the image after the edge enhancement processing, extracting edge features simple and effective method, it can extract a straight line, circle, ellipse, the conic even the edge of arbitrary shape. Hough transform in computer vision, military defense, office automation and other fields have been widespread concern and a wide range of applications. Using the Hough transform circle detection technology some units very meaningful traffic statistics, traffic statistics and analysis of the rational scheme of arrangement and rational allocation of resources, making operating systems more perfect. Home and abroad, some researchers have used the Hough transform the carrying capacity of the Statistics bus system, making the bus system to become more perfect. This thesis is the basis of Hough transform circle-based simulation in the MATLAB software. First the establishment of a video processing in MATLAB user interface, import the video taken down in the period of self-judgment recognition, video round type, and finally to identify a similar round-type statistics obtained the data.
