I'm trying to save a displayed video from my camera with OpenCV, but none of the codes I use are working. I'm using Ubuntu 14.04 and Qt as my IDE. What could you guys recommend me? The camera is Zed from stereolabs. I'm using the code they provided in their webpage, which produce a window with the camera stream. I just want to save that video. This is the code:
include <iostream>;
// OpenCV
include <opencv2 core="" core.hpp="">;
include <opencv2 highgui="" highgui.hpp="">;
include <opencv2 imgproc="" imgproc.hpp="">;
// ZED
include <zed camera.hpp="">;
// Input from keyboard char keyboard = ' ';
int main(int argc, char* argv) { // Initialize ZED color stream in HD and depth in Performance mode sl::zed::Camera zed = new sl::zed::Camera(sl::zed::HD1080); sl::zed::ERRCODE err = zed->init(sl::zed::MODE::PERFORMANCE, 0, true);
// Quit if an error occurred if (err != sl::zed::SUCCESS) { std::cout << "Unable to init the ZED:" << errcode2str(err) << std::endl; delete zed; return 1; }
// Initialize color image and depth int width = zed->getImageSize().width; int height = zed->getImageSize().height; cv::Mat image(height, width, CV_8UC4,1); cv::Mat depth(height, width, CV_8UC4,1);
// Create OpenCV windows cv::namedWindow("Image", cv::WINDOW_AUTOSIZE); cv::namedWindow("Depth", cv::WINDOW_AUTOSIZE);
// Settings for windows cv::Size displaySize(720, 404); cv::Mat imageDisplay(displaySize, CV_8UC4); cv::Mat depthDisplay(displaySize, CV_8UC4);
// Loop until 'q' is pressed while (keyboard != 'q') {
// Grab frame and compute depth in FULL sensing mode if (!zed->grab(sl::zed::SENSING_MODE::FULL)) {
// Retrieve left color image sl::zed::Mat left = zed->retrieveImage(sl::zed::SIDE::LEFT); memcpy(image.data,left.data,widthheight4*sizeof(uchar));
// Retrieve depth map sl::zed::Mat depthmap = zed->normalizeMeasure(sl::zed::MEASURE::DEPTH); memcpy(depth.data,depthmap.data,widthheight4*sizeof(uchar));
// Display image in OpenCV window cv::resize(image, imageDisplay, displaySize); cv::imshow("Image", imageDisplay);
// Display depth map in OpenCV window cv::resize(depth, depthDisplay, displaySize); cv::imshow("Depth", depthDisplay); }
keyboard = cv::waitKey(30);
}
delete zed;
}
Any suggestion will be appreciated! Thanks in advance.
