事情是这样的

正准备下班的python开发小哥哥

接到女朋友今晚要加班的电话

并给他发来一张背景模糊的自拍照

如下 ↓ ↓ ↓

敏感的小哥哥心生疑窦，难道会有原谅帽

然后python撸了一段代码 分析照片

分析下来 emmm

拍摄地址居然在 XXX酒店

小哥哥崩溃之余 大呼上当

python分析照片

小哥哥将发给自己的照片原图下载下来

并使用python写了一个脚本

读取到了照片拍摄的详细的地址

详细到了具体的街道和酒店名称

引入exifread模块

首先安装python的exifread模块，用于照片分析

pip install exifread 安装exfriead模块

GPS经纬度信息

其实我们平时拍摄的照片里，隐藏了大量的私密信息

包括 拍摄时间、极其精确 具体的GPS信息。

下面是通过exifread模块，来读取照片内的经纬度信息。

#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}

百度API将GPS转地址

这里需要使用调用百度API，将GPS经纬度信息转换为具体的地址信息。

这里，你需要一个调用百度API的ak值，这个可以注册一个百度开发者获得，当然，你也可以使用博主的这个ak

调用之后，就可以将拍摄时间、拍摄详细地址都解析出来。

def find_address_from_GPS(GPS):
    secret_key = 'zbLsuDDL4CS2U0M4KezOZZbGUY9iWtVf'
    if not GPS['GPS_information']:
        return '该照片无GPS信息'
    #经纬度信息
    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)
    #百度API转换成具体的地址
    content = response.text.replace("renderReverse&&renderReverse(", "")[:-1]
    print(content)
    baidu_map_address = json.loads(content)
    #将返回的json信息解析整理出来
    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='C:/女友自拍.jpg')
    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))

老王得到的结果是这样的

照片拍摄地址:('云南省红河哈尼族彝族自治州弥勒县', '云南省', '红河哈尼族彝族自治州', '弥勒县', '湖泉酒店-A座东南128米')

云南弥勒湖泉酒店，这明显不是老王女友工作的地方，老王搜索了一下，这是一家温泉度假酒店。

顿时就明白了
