python - 如何使用 cv2.FileStorage

Question

我曾经在 opencv c++ 中使用过 FileStorage 类，它非常有用，但我找不到如何在 opencv python 中使用它。请帮我。谢谢

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()
`

结果在'test.yml'中'

%YAML:1.0
