Hi Djme, If possible can you please share how did you enable pi cam to be used inside opencv, I know about raspicam and all but wanted to know is there a direct way. Thanks a lot for your answer :)

Hi All, Can any one please let me know how you guys are using raspicam with opencv on raspberry pi 3, as far as I know opencv doesn't support raspicam directly. Thanks a lot for your help and support.

Thanks Steven, Basically I am using raspbian pixel OS on raspberry pi 3, I will try installing UBUNTU Mate on raspberry pi and will update you,...

Hi Friends, Once we enable the experimental graphical driver, opencv 3.1 imshow does not work, it does nothing and the very basic program hangs for infinite. My sample code is as pasted below:

#include "opencv2/opencv.hpp"
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, COLOR_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;
}

I agree with you, but the imwrite also behaves in the same way, do you know how to achieve what I asked ?

Hi All, I am converting my bgr image to rgb image and then saving it to disk, but the saved image is not in rgb format.

IplImage* opencvImage_temp = cvCloneImage(inputImg);
cvCvtColor(inputImg,opencvImage_temp, CV_BGR2RGB );
opencvImage=cvCreateImage ( cvSize(480,320), opencvImage_temp->depth, opencvImage_temp->nChannels );
cvResize(opencvImage_temp, opencvImage);
cvSaveImage("stream.jpg",opencvImage_temp);

Please help me , if anyone of you faced this issue before.
