Python通过行或列将多张图片合并

    import cv2
    import numpy as np
    
    def concatenate_img(img_list, img_name, axis=1):
    img_list = [cv2.imread(img) for img in img_list]
    img = np.concatenate(([i for i in img_list]), axis=axis)
    cv2.imwrite(img_name, img)
    
    if __name__=='__main__':
    img_list = [''] # 图片的本地地址
    # 合并方式为合成一行，若要为一列，则axis改为0
    concatenate_img(img_list, img_name='img.png', axis=1)
