python3获取图片拍摄位置和时间

调试运行的环境

windows10, python3.7

准备工作

安装exifread库，requests库，申请高德地图web服务api，要用到其中的坐标转换和你地理编码功能。安装相关库的方法很简单，这里就不说了。

申请高德Web服务api的key高德开放平台

关键代码

导入要使用的模块

import requestsimport exifreadimport json

使用exifread获取图片的gps坐标和图片的拍摄时间

def __get_locations_gps(self):"""通过exifread获取图片的gps位置坐标"""# 获取exif属性with open(self.img_path, 'rb') as f:img_exif = exifread.process_file(f)print(f"图片拍摄时间：{img_exif.get('EXIF DateTimeOriginal')}")# 经度longitude_gps = img_exif['GPS GPSLongitude']longitude_gps = eval(str(longitude_gps))longitude_gps = longitude_gps[0] + longitude_gps[1] / 60 + \longitude_gps[2] / 3600longitude_gps = '{:.6f}'.format(longitude_gps)# 纬度latitude_gps = img_exif['GPS GPSLatitude']latitude_gps = eval(str(latitude_gps))latitude_gps = latitude_gps[0] + latitude_gps[1] / 60 + latitude_gps[2] / 3600latitude_gps = '{:.6f}'.format(latitude_gps)locations_gps = longitude_gps + ',' + latitude_gps# 返回gps坐标return locations_gps

调用高德地图的坐标转换，把gps坐标转成高德的坐标，提高精准度

def __convert_coordsys(self):"""调用高德API将gps坐标转换成高德地图坐标"""url = "/v3/assistant/coordinate/convert?"headers = {'User-Agent': self.user_agent}params = {# 在高德地图官网申请Web服务API类型KEY'key': self.api_key,# 经度和纬度用","分割，经度在前，纬度在后，经纬度小数点后不得超过6位'locations': self.__get_locations_gps(),# 原坐标系：gps'coordsys': 'gps'}response = requests.get(url, headers=headers, params=params)response = eval(response.text)locations_gd = response['locations']locations_gd = eval(locations_gd)locations_gd = '{:.6f},{:.6f}'.format(locations_gd[0], locations_gd[1])# 返回高德坐标print(f"高德地图经纬度：{locations_gd}")return locations_gd

我们已经拿到了高德对应的坐标值，可以返回格式地址信息，或者在浏览器上打开查看地图，按坐标搜索位置地图查看

def __get_addr(self):"""根据高德地图坐标获取地理位置"""url = "/v3/geocode/regeo?"headers = {'User-Agent': self.user_agent}params = {# 在高德地图官网申请Web服务API类型KEY'key': self.api_key,# 经度在前，纬度在后，经纬度间以“,”分割，经纬度小数点后不要超过 6 位'location': self.__convert_coordsys(),}response = requests.get(url, headers=headers, params=params)addr_data = json.loads(response.text)address = addr_data.get('regeocode').get('formatted_address')# 返回详细地址return address
