Save Image Sequence real time
Good morning,
I'm trying to create a small program that allows you to capture frames from 2 to 2 seconds of a web camera in real time. My code is working, the problem is to record the images, only one image is recorded. My idea was to have several files stored in the directory of images, with the name years months days hours min sec It is possible to do this with cvSaveImage, or is otherwise more effective to do this.
sprintf(file,"%s","/home/ricardo/Imagens/");
sprintf(file,"%d%d%d_%d%d%d.pgm\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec);
cvSaveImage(file, frame,0);
#include stdio.h
#include <stdlib.h>
#include <opencv/cv.h>
#include <opencv/highgui.h>
#include<time.h>
int main() {
char file[256];
time_t mytime;
mytime = time(NULL);
struct tm tm = *localtime(&mytime);
printf("now: %d-%d-%d %d:%d:%d\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec);
sprintf(file,"%d%d%d_%d%d%d.pgm\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec);
printf("%s",file);
getchar();
CvCapture* capture = cvCaptureFromCAM( CV_CAP_ANY );
if ( !capture ) {
fprintf( stderr, "ERROR: capture is NULL \n" );
getchar();
return -1;
}
cvNamedWindow( "mywindow", CV_WINDOW_AUTOSIZE );
while ( 1 ) {
IplImage* frame = cvQueryFrame(capture);
if ( !frame ) {
fprintf( stderr, "ERROR: frame is null...\n" );
getchar();
break;
}
cvShowImage( "mywindow", frame );
sprintf(file,"%s","/home/ricardo/Imagens/");
sprintf(file,"%d%d%d_%d%d%d.pgm\n", tm.tm_year + 1900, tm.tm_mon + 1, tm.tm_mday, tm.tm_hour, tm.tm_min, tm.tm_sec);
cvSaveImage(file, frame,0);
//sleep(2);
// Do not release the frame!
//If ESC key pressed, Key=0x10001B under OpenCV 0.9.7(linux version),
//remove higher bits using AND operator
if ( (cvWaitKey(10) & 255) == 27 ) break;
}
// Release the capture device housekeeping
cvReleaseCapture( &capture );
cvDestroyWindow( "mywindow" );
return 0;
}
