#include <iostream>#include "cv.h"#include "opencv2/opencv.hpp"using namespace std;using namespace cv;void main(){ // video read CvCapture *capture = cvCreateFileCapture("C:\\Users\\Leo\\Desktop\\Megamind.avi"); IplImage *frame; int imgIndex(0); while(1) { frame = cvQueryFrame(capture); if ( !frame ) { break; } char* imageSaveName = new char[64]; sprintf( imageSaveName, "C:\\Users\\Leo\\Desktop\\new\\%05d.jpg", imgIndex ); cvSaveImage( imageSaveName, frame ); delete[] imageSaveName; imgIndex++; } cout << "total frames: " << imgIndex << endl; cvDestroyWindow( "VideoImage" ); cvReleaseCapture( &capture ); cvReleaseImage( &frame );} |
测试数据为OpenCV自带的视频：Megamind.avi，可以在opencv\sources\samples\cpp\tutorial_code\HighGUI\video-input-psnr-ssim\video路径下查找，共270帧图像，运行结果部分截图如下：
以上这篇Opencv 视频转为图像序列的实现就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
