如何用python獲取到照片拍攝時的詳細位置(附源碼)
一.引言
先看獲取到的效果
拍攝時間:2021:12:18 16:22:13
照片拍攝地址:('內蒙古自治區包頭市昆都侖區', '內蒙古自治區', '包頭市', '昆都侖區', '多米幼兒園東南360米')
我們的女朋友給我們發來一張照片我們如何獲取到她的位置呢?
用手機拍照會帶著GPS信息,原來沒註意過這個,因此查看下並使用代碼獲取照片裡的GPS信息
查看圖片文件屬性
1.讀取照片信息,獲取坐標
ExifRead
Python library to extract EXIF data from tiff and jpeg files.
安裝
pip install exifread
讀取GPS
import exifread import re def read(): GPS = {} date = '' f = open("C:\\Users\\24190\\Desktop\\小朱學長.jpg",'rb') contents = exifread.process_file(f) for key in contents: if key == "GPS GPSLongitude": print("經度 =", contents[key],contents['GPS GPSLatitudeRef']) elif key =="GPS GPSLatitude": print("緯度 =",contents[key],contents['GPS GPSLongitudeRef']) #print(contents) read()
運行
我們得到瞭一個簡易的gps地址
如果想要讀取全部的拍攝信息:
# 讀取照片的GPS經緯度信息 def find_GPS_image(pic_path): GPS = {} date = '' with open(pic_path, 'rb') as f: tags = exifread.process_file(f) for tag, value in tags.items(): # 緯度 if re.match('GPS GPSLatitudeRef', tag): GPS['GPSLatitudeRef'] = str(value) # 經度 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 in str(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 in str(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.通過baidu Map的API將GPS信息轉換成地址。
眾所周知gps和百度的經緯度會有誤差,那麼我們需要調用百度轉換接口,這個百度目前沒有開源。
# 通過baidu Map的API將GPS信息轉換成地址。 def find_address_from_GPS(GPS): """ 使用Geocoding API把經緯度坐標轉換為結構化地址。 :param GPS: :return: """ secret_k ey = 'XXX' if not GPS['GPS_information']: return '該照片無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
然後在主函數輸出:
二.源碼附上!!!
# coding=utf-8 import exifread import re import json import requests import os # 轉換經緯度格式 def latitude_and_longitude_convert_to_decimal_system(*arg): """ 經緯度轉為小數, param arg: :return: 十進制小數 """ return float(arg[0]) + ((float(arg[1]) + (float(arg[2].split('/')[0]) / float(arg[2].split('/')[-1]) / 60)) / 60) # 讀取照片的GPS經緯度信息 def find_GPS_image(pic_path): GPS = {} date = '' with open(pic_path, 'rb') as f: tags = exifread.process_file(f) for tag, value in tags.items(): # 緯度 if re.match('GPS GPSLatitudeRef', tag): GPS['GPSLatitudeRef'] = str(value) # 經度 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 in str(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 in str(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} # 通過baidu Map的API將GPS信息轉換成地址。 def find_address_from_GPS(GPS): """ 使用Geocoding API把經緯度坐標轉換為結構化地址。 :param GPS: :return: """ secret_ke y = 'zbLsuDDL4CS2U0M4KezOZZbGUY9iWtVf' if not GPS['GPS_information']: return '該照片無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 if __name__ == '__main__': GPS_info = find_GPS_image(pic_path='小朱學長.jpg') address = find_address_from_GPS(GPS=GPS_info) print("拍攝時間:" + GPS_info.get("date_information")) print('照片拍攝地址:' + str(address))
註意事項
1.照片的地址信息等,一般的手機相機默認是打開的。
2.微信和QQ裡面發送原圖,信息都會完整的保留下來。
3.代碼裡面需要處理在照片我放到瞭代碼的同文件夾下,所以沒有寫路徑,大傢可以自己寫路徑,或者放到於代碼相同的路徑下即可。
