图片合成视频C++

本文主要是介绍图片合成视频C++，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

#include <iostream>
#include <opencv2\opencv.hpp>


using namespace std;
using namespace cv;
void Image_To_Video();

int main()
{
	Image_To_Video();
	waitKey(0);
	return 0;
}

void Image_To_Video()
{
	char image_name[80];
	VideoWriter writer;
	int frame_fps = 32;
	int frame_width = 1241;
	int frame_height = 376;

	writer = VideoWriter("H:\\ziliao\\real_vehicle_data\\slam_dataset32.avi", CV_FOURCC('X', 'V', 'I', 'D'),
		frame_fps, Size(frame_width, frame_height), true);
	cout << "frame_width is " << frame_width << endl;
	cout << "frame_height is " << frame_height << endl;
	cout << "frame_fps is " << frame_fps << endl;
	//namedWindow("image to vedio", CV_WINDOW_AUTOSIZE);
	int num = 8456;// the number of picture
	int i = 1;
	Mat img;

	for (i = 1; i < num; i++)
	{
		//cout << "1\n";
		sprintf_s(image_name, "H:\\ziliao\\real_vehicle_data\\total_picture\\%06d.png", i);
		cout << image_name << endl;
		img = imread(image_name);// imread picture
		if (img.empty())
		{
			cout << "can not load image file...\n";
			break;
		}
		//imshow("image to vedio", img);
		writer << img;
		if (waitKey(30) == 27 || i == num)
		{
			cout << "please press the  ESC key " << endl;
			break;
		}
		cout << "write end!!\n";

	}
}
