采用块匹配法计算相邻两帧图像的运动矢量，并显示计算的矢量结果。其中使用了opencv里面的函数。需先安装和加入opencv的库。-Using the 3 step block matching algorithm to compute the motion vector of two consecutive frames.

利用opencv读取一个视频里的图像，并且计算出来多少帧，然后分别存储到硬盘里。-Using opencv to read each frame in a video, and then compute how many frames the video have, then store the data in the computer.

这个程序的目的是为了收集数据集的一个对象和分割区域.它展示了如何使用相机的校准模式来计算校准模式是平面的单应性。-This program s purpose is to collect data sets of an object and its segmentation mask.It shows how to use a calibrated camera together with a calibration pattern to compute the homography of th
