我是OpenCV的初学者，我尽力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;
}
为静态链接编译这种方式：
