保存 Opencv 图像 [英] Saving Opencv Images

问题描述

我有一个在 OpenCV (C API) 中运行的窗口，我想从该窗口中保存一系列图像，而无需保存前一个图像.所以一段时间后，窗口应该保存刷新，然后保存并刷新等，我的计算机上应该有多个图像.我还没有完全到达那里，但我正在尝试做类似的事情:

Hi I have a window running in OpenCV (C API) and I would like to save a series of images from the window without saving over the previous image. So after a certain time the window should save refresh, then save and refresh etc. and I should have multiple images on my computer. I haven't quite gotten there but I am trying to do something like:

if (counter>=300)  {
int counterimg=1;
//reset background to black
cvSet(imgScribble,cvScalar(0,0,0);
//save image to file 
cvSaveImage("/Documents/testframe.jpg" [counterimg], frame); 
counter=0;
//increase counter for saving
counterimg+=1;  
}

推荐答案

你只需要创建一个带有图片索引的路径名:

You just need to create a path name with the index of the image:

char path[512];
snprintf(path, 512, "/Documents/testframe%03d.jpg", counterimg);
cvSaveImage(path, frame);

%03d"将被000"、001"、002"等替换

The "%03d" will be replaced by "000", "001", "002", etc.
