如何在python的空白背景图像（200x200）中随机添加20张图像（10x10）？

Question

I want the 10 small images to be placed in this circle

我正在一个小项目中，将几张大小（10 w x 10 h）的图像随机放置或放置在另一张图像中，这些图像将在python中用作大小（200 w x 200 h）的背景。这些小图像应放在背景图像中的任意位置。

我有20张尺寸为（10x10）的小图像和一张尺寸为（200x200）的空白图像背景。我想将20张小图片放在背景中随机位置的空白背景图片中。

有没有办法在Python中做到这一点？

代码

# Depencies importation
import cv2

# Saving directory
saving_dir = "../Saved_Images/"

# Read the background image
bgimg = cv2.imread("../Images/background.jpg")

# Resizing the bacground image
bgimg_resized = cv2.resize(bgimg, (2050,2050))

# Read the image that will be put in the background image (exemple of 1)
small_img = cv2.imread("../Images/small.jpg")

# Convert the resized background image to gray
bgimg_gray = cv2.cvtColor(bgimg, cv2.COLOR_BGR2GRAY) 
# Convert the grayscale image to a binary image
ret, thresh = cv2.threshold(bgimg_gray,127,255,0)
# Determine the moments of the binary image
M = cv2.moments(thresh)
# calculate x,y coordinate of center
cX = int(M["m10"] / M["m00"])
cY = int(M["m01"] / M["m00"])

# drawing the circle in the background image
circle = cv2.circle(bgimg, (cX, cY), 930, (0,0,255), 9)

print(circle)

# Saving the new image
cv2.imwrite(saving_dir+"bgimg"+".jpg", bgimg)

cv2.namedWindow('image', cv2.WINDOW_NORMAL)
cv2.resizeWindow("Test", 1000, 1200)
# Showing the images
cv2.imshow("image", bgimg)
# Waiting for any key to stop the program execution
cv2.waitKey(0)

上面的代码是针对一张图片的，我想针对20张图片进行处理并将其放置在随机位置

假设您有that背景图片background.jpg（减小到200x200 px）和10张图片：image01.png，image02.png ... image10.png（10x10 px ）。然后：

import glob
import random
from PIL import Image


img_bg = Image.open('circle.jpg')
width, height = img_bg.size
images = glob.glob('*.png')
for img in images:
    img = Image.open(img)
    x = random.randint(40, width-40)
    y = random.randint(40, height-40)
    img_bg.paste(img, (x, y, x+10, y+10))
img_bg.save('result.png', 'PNG')

输出图像：
