2021/5/14 1:25:11
本文主要是介绍用Python读取照片拍摄的详细信息(拍摄时间、地址等),对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
前言
其实咱们平时拍摄的照片里隐藏了大量的私密信息,例如:拍摄时间、极其精确的GPS信息等。接下来尝试用python脚本分析照片,获取照片原图的拍摄信息。
1、准备条件
pip install exifread
安装exifread模块,用来读取照片内的经纬度信息。
2、详细代码
import re import json import requests import exifread # 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 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(): # 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 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} # 通过baidu Map的API将GPS信息转换成地址 def find_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: """ # 调用百度API的ak值,这个可以注册一个百度开发者获得 secret_key = 'zbLsuDDL4CS2U0M4KezOZZbGUY9iWtVf' if not 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 if __name__ == '__main__': path = r'D:\Users\Administrator\Desktop\图片.jpg' # 图片存放路径 GPS_info = find_GPS_image(pic_path=path) address = find_address_from_GPS(GPS=GPS_info) print("拍摄时间:" + GPS_info.get("date_information")) print('照片拍摄地址:' + str(address))
