写入读取pickle文件和yaml文件

一、pickle文件

1.写入

a = {'mtx':mtx, 'dist':dist}
with open('./cal_pickle.p','wb') as file:
    pickle.dump(a, file)

pickle文件直接打开是乱码，要用读取的方式打开
2.读取

file = open("cal_pickle.p", 'rb')
parms = pickle.load(file)
mtx = parms['mtx']
dist = parms['dist']

二、yaml文件

1.写入
2.读取

f = open("calibration.yaml",'r',encoding="utf-8")
data = yaml.load(f)
mtx = data["CameraMat"]['data']
dist = data["DistCoeff"]['data']
