实际上就是获取EXIF信息。就是照片拍摄时候保存的经纬度信息

import exifread
    import re
    import json
    from exifread.classes import StringCls
    import requests
    import os
     
    #转换经纬度格式
    def latitude_and_longitude_convert_to_decimal_system(*arg):
        """
        经纬度转为小数, param arg:
        :return: 十进制小数
        """
        return float(arg[0]) + ((float(arg[1]) + (float(arg[2].split('/')[0]) / float(arg[2].split('/')[-1]) / 60)) / 60)
     
    #读取照片的GPS经纬度信息

        GPS = {
        }
