打开cv c ++拼接图像不合适

Question

嗨我试图用opencv缝合图像，但它不能正常工作，它会在一段时间内保存黑色图片或扭曲的图像。我如何完美匹配图像并缝合它

JNIEXPORT int JNICALL Java_org_opencv_samples_cameracalibration_Sample3Native_FindFeatures（         JNIEnv *，jobject，jlong​​ im1，jlong​​ im2，jlong​​ im3，jint no_images，         Mat img1，Mat imgz）{

vector<Mat> imgs;
bool try_use_gpu = false;
// New testing
Mat& temp1 = *((Mat*) im1);
Mat& temp2 = *((Mat*) im2);

Mat& pano = *((Mat*) im3);

Mat img = cvLoadImage("/storage/sdcard0/panoTmpImage/im0.jpeg", 1);

Mat img2 = cvLoadImage("/storage/sdcard0/panoTmpImage/im1.jpeg", 1);
Mat img3 = cvLoadImage("/storage/sdcard0/panoTmpImage/im2.jpeg", 1);

Mat img4 = cvLoadImage("/storage/sdcard0/panoTmpImage/im3.jpeg", 1);

if (!img.data) {
    waitKey(5000);
    return -1;
}
imgs.push_back(img);
imgs.push_back(img2);
imgs.push_back(img3);
imgs.push_back(img4);

if (!img.empty()) {

    Stitcher stitcher = Stitcher::createDefault();
    Stitcher::Status status = stitcher.stitch(imgs, pano);
    if (status != Stitcher::OK) {
        cout << "Can't stitch images, error code = " << int(status) << endl;
        return -1;
    }
} else {
    return -2;
}

return 3;

}

}
