我是OpenCV的初学者,并尽我所能在嵌入式平台上运行一个简单的应用程序.我交叉编译了OpenCV 2.4.4并根据摄像头和GUI支持的需要构建了WITH_GTK = ON,WITH_UNICAP = ON,WITH_V4L = ON.以下示例代码在主机上交叉编译:

#include <opencv/cv.h>
#include <opencv/highgui.h>
using namespace cv; 
int main(int, char**)
{
    VideoCapture cap(0); // open the default camera
    if (!cap.isOpened()) // check if we succeeded
        return -1;

    Mat edges;
    namedWindow("edges", 1);
    for (;;) {
        Mat frame;
        cap >> frame;   // get a new frame from camera
        cvtColor(frame, edges, CV_BGR2GRAY);
        GaussianBlur(edges, edges, Size(7, 7), 1.5, 1.5);
        Canny(edges, edges, 0, 30, 3);
        imshow("edges", edges);
        if (waitKey(30) >= 0)
            break;
    }
    return 0;
}
