相机调焦之校准版-棋盘格生成

今天在实验室搭建试验台，由于实验室的相机需要调焦。生成棋盘格碰见师弟们不会，我也就顺便把程序写个博客上传

import cv2
import numpy as np

width = 1800
height = 1600
length = 75

image = np.zeros((width,height),dtype = np.uint8)
print(image.shape[0],image.shape[1])

for j in range(height):
    for i in range(width):
        if((int)(i/length) + (int)(j/length))%2:
            image[i,j] = 255;
cv2.imwrite("chess6.jpg",image)
cv2.imshow("chess",image)
cv2.waitKey(0)
