OpenCV Assertion Error in Stitching

Question

I'm doing stitching on two images, and has this error while debugging(compile successfully but when run it breaks):

Assertion failed ==CV_8Uc3> in unknown function.

And here is the code:

int main(int argc, char ** argv)
{
    Mat im1=imread("panorama_image1.jpg", CV_LOAD_IMAGE_GRAYSCALE);
    Mat im2=imread("panorama_image2.jpg", CV_LOAD_IMAGE_GRAYSCALE);

    Mat result;
    vector<Mat> imgs;
    imgs.push_back(im1);
    imgs.push_back(im2);
    cv::Stitcher stitcher=cv::Stitcher::createDefault(false);
    stitcher.stitch(imgs,result);

    namedWindow("Mosaic", CV_WINDOW_AUTOSIZE);
    imshow("Mosaic",result);
    waitKey(0);

    return 0;
}

I've not been able to find an error in this code. And the linker libraries are correct(use D version such as opencv_core244d.lib , opencv_stitching244d.lib etc

Answer 1

I think sgarizvi is right, loading in color solved a similar problem for me:

Mat im1=imread("panorama_image1.jpg", CV_LOAD_IMAGE_COLOR);
Mat im2=imread("panorama_image2.jpg", CV_LOAD_IMAGE_COLOR);
