摘要

本文提出的运动轨迹检测方法包括图像分割和透视变换。首先处理视频采集图像,然后进行灰度化、二值化、 连通域标记等处理,再引入Canny 边缘检测算法提取图像轮廓,经MATLAB 编程求得影子的轮廓像素坐标。最后根据透视变 换,求得视频中影子的实际坐标,并在二维和三维坐标系下描绘了其运动轨迹图。

Abstract

A method of motion trajectory detection is proposed in this paper, including image segmentation and perspective transformation. First of all, the video images are processed. Then the images are dealed with Grayscale, Binarization and Connected Component Labeling. The contour of images are acquired with Canny edge detection algorithm, and the coordinates of contour pixel are obtained with the MATLAB programming. Finally, the actual coordinates of the video images are obtained with Perspective Transformation. And shadow motion trajectory is simulated in the two-dimensional and three-dimensional coordinate system.
