一.引言
先看获取到的效果
拍摄时间:2021:12:1816:22:13
照片拍摄地址:('内蒙古自治区包头市昆都仑区','内蒙古自治区','包头市','昆都仑区','多米幼儿园东南360米')
我们的女朋友给我们发来一张照片我们如何获取到她的位置呢?
用手机拍照会带着GPS信息,原来没注意过这个,因此查看下并使用代码获取照片里的GPS信息
查看图片文件属性
1.读取照片信息,获取坐标
ExifRead
Python library to extract EXIF data from tiff and jpeg files.
安装
pip install exifread
读取GPS
import exifread
import re
defread():
GPS ={}
date =''
f =open("C:\\Users\\24190\\Desktop\\小朱学长.jpg",'rb')
contents = exifread.process_file(f)for key in contents:if key =="GPS GPSLongitude":print("经度 =", contents[key],contents['GPS GPSLatitudeRef'])elif key =="GPS GPSLatitude":print("纬度 =",contents[key],contents['GPS GPSLongitudeRef'])#print(contents)
read()
运行
我们得到了一个简易的gps地址
如果想要读取全部的拍摄信息:
# 读取照片的GPS经纬度信息deffind_GPS_image(pic_path):
GPS ={}
date =''withopen(pic_path,'rb')as f:
tags = exifread.process_file(f)for tag, value in tags.items():# 纬度if re.match('GPS GPSLatitudeRef', tag):
GPS['GPSLatitudeRef']=str(value)# 经度elif re.match('GPS GPSLongitudeRef', tag):
GPS['GPSLongitudeRef']=str(value)# 海拔elif re.match('GPS GPSAltitudeRef', tag):
GPS['GPSAltitudeRef']=str(value)elif re.match('GPS GPSLatitude', tag):try:
match_result = re.match('\[(\w*),(\w*),(\w.*)/(\w.*)\]',str(value)).groups()
GPS['GPSLatitude']=int(match_result[0]),int(match_result[1]),int(match_result[2])except:
deg,min, sec =[x.replace(' ','')for x instr(value)[1:-1].split(',')]
GPS['GPSLatitude']= latitude_and_longitude_convert_to_decimal_system(deg,min, sec)elif re.match('GPS GPSLongitude', tag):try:
match_result = re.match('\[(\w*),(\w*),(\w.*)/(\w.*)\]',str(value)).groups()
GPS['GPSLongitude']=int(match_result[0]),int(match_result[1]),int(match_result[2])except:
deg,min, sec =[x.replace(' ','')for x instr(value)[1:-1].split(',')]
GPS['GPSLongitude']= latitude_and_longitude_convert_to_decimal_system(deg,min, sec)elif re.match('GPS GPSAltitude', tag):
GPS['GPSAltitude']=str(value)elif re.match('.*Date.*', tag):
date =str(value)return{'GPS_information': GPS,'date_information': date}
2.通过baidu Map的API将GPS信息转换成地址。
众所周知gps和百度的经纬度会有误差,那么我们需要调用百度转换接口,这个百度目前没有开源。
# 通过baidu Map的API将GPS信息转换成地址。deffind_address_from_GPS(GPS):"""
使用Geocoding API把经纬度坐标转换为结构化地址。
:param GPS:
:return:
"""
secret_k ey ='XXX'ifnot GPS['GPS_information']:return'该照片无GPS信息'
lat, lng = GPS['GPS_information']['GPSLatitude'], GPS['GPS_information']['GPSLongitude']
baidu_map_api ="http://api.map.baidu.com/geocoder/v2/?ak={0}&callback=renderReverse&location={1},{2}s&output=json&pois=0".format(
secret_key, lat, lng)
response = requests.get(baidu_map_api)
content = response.text.replace("renderReverse&&renderReverse(","")[:-1]print(content)
baidu_map_address = json.loads(content)
formatted_address = baidu_map_address["result"]["formatted_address"]
province = baidu_map_address["result"]["addressComponent"]["province"]
city = baidu_map_address["result"]["addressComponent"]["city"]
district = baidu_map_address["result"]["addressComponent"]["district"]
location = baidu_map_address["result"]["sematic_description"]return formatted_address, province, city, district, location
然后在主函数输出:

注意事项
1.照片的地址信息等,一般的手机相机默认是打开的。
2.微信和QQ里面发送原图,信息都会完整的保留下来。
3.代码里面需要处理在照片我放到了代码的同文件夹下,所以没有写路径,大家可以自己写路径,或者放到于代码相同的路径下即可。
(有任何问题的话,欢迎评论区或者私信我嗷,我都会看的!)
