Python如何提取图片像素点坐标值？

Python提问，Python如何提取图片像素点坐标值？。给个代码例子，各位！

可以用numpy的column_stack和where函数来获取像素点在某阈值范围内的坐标。例子：

import numpy as np
from PIL import Image 

image = Image.open("tqc.jpg")
pixels = np.asarray(image)
# Set threshold level
threshold_level = 50
# Find coordinates of all pixels below threshold
coords = np.column_stack(np.where(pixels < threshold_level))
print(coords)

或者要获取每个像素点坐标，参考这里的代码： https://stackoverflow.com/questions/60782965/extract-x-y-coordinates-of-each-pixel-from-an-image-in-python https://stackoverflow.com/questions/60782965/extract-x-y-coordinates-of-each-pixel-from-an-image-in-python

可以用opencv获取像素点的rgb值（pip install opencv-python）

有帮助麻烦点个采纳【本回答右上角】，谢谢~~

import cv2 
# 读取图像
img = cv2.imread("edge.jpg")
 
# 查看 (10,10) 位置的RGB 
# 注意：此处返回顺序为 [B, G, R]
print(img[10,10])
