将多张图片结合为一张图片
案例一：

import numpy as np
import os
import glob
# img1=cv2.imread(r"F:\myyolov5\202302141303-L2_27.jpg")
# print(img1.shape)

# 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)

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。

案例二：

if not os.path.exists(outputpath):

# print(inputpath)
output = open_image(inputpath)
print(output.shape)
ohhh=np.concatenate(output,1)
print(ohhh.shape)
# ohhh = combine_images(output,1,output.shape[0]) # 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。
# print(ohhh.shape)
