根据女友的一张照片,程序员男友用python就获取到她的详细位置
一.引言
先看获取到的效果拍摄时间:2021:12:18 16:22:13 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GPSimport exifread import re def read(): GPS = { } date = "" f = open("C:Users24190Desktop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 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}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。 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: """ 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
然后在主函数输出:

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,或者放到与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哦,我都会看的!)
