用python找出那些被“标记”的照片 源码传送门 环境准备 下面的两个第三方模块都可以直接通过pip快速安装,这里使用py36作为运行环境。 python3.6 requests exifread 思路 遍历目录 拉取数据集合 遍历集合取得exif exif信息整理,并获取实体地址 拷贝文件到结果样本目录 生成json报告文件 基础知识 下面是现今相片中会存在与GPS相关的关键字,大牛亦可一比带过~ [参考] { "GPSVersionID": "GPS版本", "GPSLatitudeRef": "南北纬", "GPSLatitude": "纬度", "GPSLongitudeRef": "东西经", "GPSLongitude": "经度", "GPSAltitudeRef": "海拔参照值", "GPSAltitude": "海拔", "GPSTimeStamp": "GPS时间戳", "GPSSatellites": "测量的卫星", "GPSStatus": "接收器状态", "GPSMeasureMode": "测量模式", "GPSDOP": "测量精度", "GPSSpeedRef": "速度单位", "GPSSpeed": "GPS接收器速度", "GPSTrackRef": "移动方位参照", "GPSTrack": "移动方位", "GPSImgDirectionRef": "图像方位参照", "GPSImgDirection": "图像方位", "GPSMapDatum": "地理测量资料", "GPSDestLatitudeRef": "目标纬度参照", "GPSDestLatitude": "目标纬度", "GPSDestLongitudeRef": "目标经度参照", "GPSDestLongitude": "目标经度", "GPSDestBearingRef": "目标方位参照", "GPSDestBearing": "目标方位", "GPSDestDistanceRef": "目标距离参照", "GPSDestDistance": "目标距离", "GPSProcessingMethod": "GPS处理方法名", "GPSAreaInformation": "GPS区功能变数名", "GPSDateStamp": "GPS日期", "GPSDifferential": "GPS修正" } 初始化 考虑到exifread的模块中有大量的logging输出,这里将它的level级别调到最高。 然后下边的KEY是某站在高德地图API的时候遗留下来的 我也很尴尬。。就当福利了 import os import time import json import random import logging import requests import exifread logging.basicConfig(level=logging.CRITICAL) KEY = "169d2dd7829fe45690fabec812d05bc3" 主逻辑函数 def main(): # 预设后缀列表 types = ["bmp", "jpg", "tiff", "gif", "png"] #结果数据集合 picex = [] # 文件存储路径 saves = "$" + input("| SavePath: ").strip() # 文件搜索路径 并遍历所有文件返回文件路径列表 pools = jpgwalk(input("| FindPath: "), types) #存储目录 savep = "%s/%s" % (os.getcwd().replace("\\", "/"), saves) if savep in pools: pools.remove(savep) # 遍历数据集并获取exif信息 for path in pools: res = getEXIF(path) if res: picex.append(res) # 结果报告 print("| Result %s" % len(picex)) # 如果存在结果 保存结果到json并讲相关图片复制到该目录下 if picex: #创建目录 if not os.path.exists(saves): os.mkdir(saves) #生成一个4格缩进的json文件 with open("%s/%s.json" % (saves, saves), "wb") as f: f.write(json.dumps(picex, ensure_ascii=False, indent=4).encode("utf8")) #copy图像到该目录 for item in picex: source_path = item["Filename"] with open("%s/%s" % (saves, source_path.split("/")[-1]), "wb") as f_in: with open(source_path, "rb") as f_out: f_in.write(f_out.read()) 遍历方法 遍历指定及其所有下级目录,并返回全部的图片的路径集合,这里要注意的是每次扫描后的拷贝行为都会生成缓存,所以通过指定 $ 来避开。 # 获取指导目录全部的图片路径 def jpgwalk(path, types): _start = time.time() _pools = [] # 遍历该目录 并判断files后缀 如符合规则则拼接路径 for _root, _dirs, _files in os.walk(path): _pools.extend([_root.replace("\\", "/") + "/" + _item for _item in _files if _item.split(".")[-1].lower() in types and "$" not in _root]) #报告消耗时间 print("| Find %s \n| Time %.3fs" % (len(_pools), time.time() - _start)) return _pools 经纬度格式化 度分秒转浮点,方便api调用查询,因为存在一些诡异的数据比如 1/0,所以默认返回0 def cg(i): try: _ii = [float(eval(x)) for x in i[1:][:-1].split(', ')] _res = _ii[0] + _ii[1] / 60 + _ii[2] / 3600 return _res except ZeroDivisionError: return 0 EXIF信息整理 考虑到大部分的设备还未开始支持朝向、速度、测量依据等关键字,这里暂时只使用比较常见的,如有需要的朋友可以自行添加。毕竟得到的信息越多对社工有更大的帮助。 def getEXIF(filepath): #基础关键字 _showlist = [ 'GPS GPSDOP', 'GPS GPSMeasureMode', 'GPS GPSAltitudeRef', 'GPS GPSAltitude', 'Image Software', 'Image Model', 'Image Make' ] #GPS关键字 _XYlist = ["GPS GPSLatitude", "GPS GPSLongitude"] #时间关键字 _TimeList = ["EXIF DateTimeOrigina", "Image DateTime", "GPS GPSDate"] #初始化结果字典 _infos = { 'Filename': filepath } with open(filepath, "rb") as _files: _tags = None # 尝试去的EXIF信息 try: _tags = exifread.process_file(_files) except KeyError: return # 判断是否存在地理位置信息 _tagkeys = _tags.keys() if _tags and len(set(_tagkeys) & set(_XYlist)) == 2 and cg(str(_tags["GPS GPSLongitude"])) != 0.0: for _item in sorted(_tagkeys): if _item in _showlist: _infos[_item.split()[-1]] = str(_tags[_item]).strip() # 经纬度取值 _infos["GPS"] = (cg(str(_tags["GPS GPSLatitude"])) * float(1.0 if str(_tags.get("GPS GPSLatitudeRef", "N")) == "N" else -1.0), cg(str(_tags["GPS GPSLongitude"])) * float(1.0 if str(_tags.get("GPS GPSLongitudeRef", "E")) == "E" else -1.0)) # 获取实体地址 _infos["address"] = address(_infos["GPS"]) # 获取照片海拔高度 if "GPS GPSAltitudeRef" in _tagkeys: try: _infos["GPSAltitude"] = eval(_infos["GPSAltitude"]) except ZeroDivisionError: _infos["GPSAltitude"] = 0 _infos["GPSAltitude"] = "距%s%.2f米" % ("地面" if int( _infos["GPSAltitudeRef"]) == 1 else "海平面", _infos["GPSAltitude"]) del _infos["GPSAltitudeRef"] # 获取可用时间 _timeitem = list(set(_TimeList) & set(_tagkeys)) if _timeitem: _infos["Dates"] = str(_tags[_timeitem[0]]) return _infos 地址转换 一个简单的爬虫,调用高德地图api进行坐标转换,考虑到原本是跨域,这里添加基础的反防爬代码。这里有个小细节,海外的一律都取不到(包括台湾),可以通过更换googlemap的api来实现全球查询。 def address(gps): global KEY try: # 随机UA _ulist = [ "Mozilla/5.0 (Windows NT 6.1;
