小弟於本網址中學習車道辨識
不過在一開始的相機校正中無法正常運作
參考大量文章後依舊無法解決
煩請大神指點

import cv2
import numpy as np

img=cv2.imread('C:/Users/humaolin/PycharmProjects/pythonProject/camera_cal/calibration1.jpg')
gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

objpoints=[]
imgpoints=[]
img_size=gray.shape[1::-1]

ret, corners = cv2.findChessboardCorners(gray, (9,6),None)
ret, mtx, dist, rvecs, tvecs = cv2.calibrateCamera(objpoints, imgpoints, img_size,None,None)
undistort_img = cv2.undistort(img, mtx, dist, None, mtx)


cv2.imshow('gq',undistort_img)
cv2.waitKey()```
以上是我的程式碼
下方為報錯訊息
