将多张图片结合为一张图片

案例一：

import cv2
import numpy as np
import os
import glob

# img1=cv2.imread(r"F:\myyolov5\202302141303-L2_27.jpg")
# print(img1.shape)
# img2=cv2.imread(r"F:\myyolov5\202303011344R2_112_1.jpg")
# print(img2.shape)
# img1=cv2.resize(img1,(512,500))
# img2=cv2.resize(img2,(512,500))
# inputs=np.hstack((img1,img2))
# # cv2.imshow("input img",inputs)
# cv2.imwrite(r"F:\Desktop\a.jpg",inputs)
# cv2.waitKey(0)


def open_image(path1):
    img_path = glob.glob(path1)
    print(img_path)
    return np.array([cv2.imread(true_path,0) for true_path in img_path])

def combine_images(datasets,newraw,newcol):
    raw,col = datasets[0].shape
    newimage = np.zeros((newraw*raw,newcol*col))
    for i in range(0,newraw):

            for ii in range(0,raw):
                for jj in range(0,col):
                    newimage[i*raw+ii][j*col+jj] = output[i*newcol+j][ii][jj]

    return newimage


if __name__ == '__main__':
    inputpath = 'F:\Desktop\myfile\*'
    output = open_image(inputpath)

    ohhh = combine_images(output,1,14)  # 这个4,6的意思就是，我的图片通过那个打开的函数之后，变成了一个大的ndarray里面有24张图片，我想让他们以，行4列6，的形式组合起来。
    cv2.imwrite(r"F:\Desktop\b.jpg",ohhh)
