如何使用cv2.FileStorage

Question

我习惯使用opencv c ++中的FileStorage类，它非常有用，但我无法在opencv python中找到它的使用方法。请帮我。感谢

Answer 1

`import cv2
 import numpy as np
 f = cv2.FileStorage('test.yml',flags=1)
 a = np.zeros((10,10),dtype=np.uint8)
 f.write(name='matrix',value=a)
 f.release()
`

结果是'test.yml' “

%YAML:1.0
