如何显示不同分辨率的垂直2张图像？

Question

我尝试过：

import cv2
import numpy as np
import matplotlib.pyplot as plt

top=cv2.imread('top.jpg')

https://imgur.com/KHwU6z0

bottom=cv2.imread('bottom.jpg')

https://imgur.com/eO04Nj2

numpy_vertical= np.vstack((top, bottom))


cv2.imshow('detected', numpy_vertical)
cv2.imwrite('detected.jpg', numpy_vertical)

ValueError：级联轴的所有输入数组维必须完全匹配，但是沿着维1，索引为0的数组的大小为2878，索引为1的数组的大小为5760]

Answer 1

import cv2
import numpy as np

first = cv2.imread(r"path.... \first.png")
second = cv2.imread(r"path.... \second.png")

h1, w1, c1 = first.shape

h2, w2, c2 = second.shape

h, w= h1+h2, max(w1, w2)

out_image = np.zeros((h,w,c1))

out_image[:h1,:w1, ] = first

out_image[h1:h1+h2,:w2, ] = second

cv2.imwrite(r"path ......out.png", out_image)
