python 通过exifread读取照片信息

import exifread

import json

import urllib.request

# Open image file for reading (binary mode)

f = open('001.jpg', 'rb')

# Return Exif tags

tags = exifread.process_file(f)

'''

#打印所有照片信息

for tag in tags.keys():

print("Key: {}, value {}".format(tag, tags[tag]))

'''

#打印照片其中一些信息

print('拍摄时间：', tags['EXIF DateTimeOriginal'])

print('照相机制造商：', tags['Image Make'])

print('照相机型号：', tags['Image Model'])

print('照片尺寸：', tags['EXIF ExifImageWidth'], tags['EXIF ExifImageLength'])

#获取经度或纬度

def getLatOrLng(refKey, tudeKey):

LatOrLng=LatOrLng*(-1)

return LatOrLng

#调用百度地图API通过经纬度获取位置

def getlocation(lat,lng):

url = 'http://api.map.baidu.com/geocoder/v2/?location=' + lat + ',' + lng + '&output=json&pois=1&ak=申请的百度地图KEY'
