Pyton生成标定板

Mar 26, 2018

做一个和Opencv相关的项目调研，这里留下些记录….

使用Opencv进行图摄像头标定时，要用到标定板。下面用Python开始生成一个标定板：

#!/usr/bin/env python2
# -*- coding: utf-8 -*-

import cv2
import numpy as np
import matplotlib.pyplot as plt

# 宽450像素
width = 450
# 高350像素
height = 350
# 50 x 50 一个单元格
length = 50

img = np.zeros((width, height), dtype=np.uint8)

for j in range(height):
    for i in range(width):
        if ((int)(i / length) + (int)(j / length)) % 2:
            img[i, j] = 255
# 将标定板保存为图checkboard.jpg
cv2.imwrite('checkerborad.jpg', img)
# 使用matplotlib查看生成的标定板
plt.subplot(111), plt.imshow(img, cmap='gray'), plt.title('Output')
plt.show()
