推荐答案

从评论到问题，您说:

我不想将第一张图片中的一半与第二张图片中的另一半融合在一起.我只是想打印两张图像，一张紧挨着另一张

I dont want to blend half from the first picture with the other half from the second. I just waint to print both images, one near the other one

因此，从这些图像开始:

So, starting from these images:

您想要这个结果吗?

请注意，如果两个图像的高度相同，则不会看到黑色背景.

Note that if both images have the same height, you won't see the black background.

代码:

#include <opencv2\opencv.hpp>
using namespace cv;

int main()
{
    // Load images
    Mat3b img1 = imread("path_to_image_1");
    Mat3b img2 = imread("path_to_image_2");

    // Get dimension of final image
    int rows = max(img1.rows, img2.rows);
    int cols = img1.cols + img2.cols;

    // Create a black image
    Mat3b res(rows, cols, Vec3b(0,0,0));

    // Copy images in correct position
    img1.copyTo(res(Rect(0, 0, img1.cols, img1.rows)));
    img2.copyTo(res(Rect(img1.cols, 0, img2.cols, img2.rows)));

    // Show result
    imshow("Img 1", img1);
    imshow("Img 2", img2);
    imshow("Result", res);
    waitKey();

    return 0;
}
