cv2多图拼接

 刚好需要写个脚本实现个小功能，把多张图片合成一张大图，用到的第三方库有numpy和opencv

import numpy as np
import cv2


def merge_image(image_list, x_num=2, y_num=2):
    image_num = len(image_list)
    frame = np.zeros((720, 1080), dtype=np.uint8)
    new_image_list = []
    x_image_list = []
   
    if image_num%2 == 0:
         frame = np.zeros((720, 1080), dtype=np.uint8)
         image = cv2.imread("10005001_1618537982.jpg")
         for image in image_list:
             frame = cv2.resize(image, (1080, 720), interpolation=cv2.INTER_AREA) # 每张图片的大小可自行resize
             new_image_list.append(frame)
         for x in range(x_num):
             htich = np.hstack([i for i in new_image_list[y_num*x:y_num*(x+1)]])
             x_image_list.append(htich)
         vtich = np.vstack(x_image_list)
    else: # 在这里如果图片列表是单数的话，你可以填充一个空白图片
        pass
    return vtich


if __name__ == "__main__":

    image = cv2.imread("test.jpg")
    image_list = [image,image,image,image]  # 这里存放你的图片帧列表
    big_image = merge_image(image_list,2,2)  # x_num为行数、y_num为列数，x与y的积为图像列表的长度
    cv2.imwrite("merge_image.jpg",big_image)
