See3cam Ubuntu-14.04 EclipseC++库错误

Question

我试着用Eclipse访问See3cam CU40相机，它的格式是Y16而不是RGB。我已经安装了制造商提供的所需的OpenCV库，但在使用libv4l2时遇到了问题。示例：

#include "opencv2/opencv.hpp"
#include "opencv2/highgui/highgui.hpp"

#include <iostream>
#include <ctype.h>


using namespace cv;
using namespace std;

int main(int, char**)
{
VideoCapture cap(0);
if(!cap.isOpened()){  // check if default camera is opened
    cout << "***Could not initialize capturing...***\n";
    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;
}
// the camera will be deinitialized automatically in VideoCapture destructor
return 0;
}

控制台出错：

libv4l2: error set_fmt gave us a different result then try_fmt!
HIGHGUI ERROR: libv4l unable convert to requested pixfmt
libv4l2: error set_fmt gave us a different result then try_fmt!

​

这是生成的窗口

期望的结果应该是包含摄像机捕获的边缘视频流的窗口，然而，帧是三重的，并且有些重叠。有人能帮上忙吗？谢谢。

See3Cam_CU40的输出是Y16-拜耳10位RGB帧！您需要使用修改版本的opencv videoio模块作为described here！请访问此处
