python提取照片坐标信息的代码如下所示：

from PIL import Imagefrom PIL.ExifTags import TAGSimport osoutput="Z://result.csv"out=open(output,'a')out.write('lat,lon\n')fpath="Z://iphonephoto"for item in os.walk(fpath): ob=item[2] for i in ob:  name=fpath+'/'+str(i)  ret={}  try:   img=Image.open(name)   if hasattr(img,'_getexif'):    exifinfo=img._getexif()    if exifinfo !=None:     for tag,value in exifinfo.items():      decoded=TAGS.get(tag,tag)      ret[decoded]=value      N1 = ret['GPSInfo'][2][0][0]      N2 = ret['GPSInfo'][2][1][0]      N3 = ret['GPSInfo'][2][2][0]      N=int(N1)+int(N2)*(1.0/60)+int(N3)*(1.0/360000)      E1 = ret['GPSInfo'][4][0][0]      E2 = ret['GPSInfo'][4][1][0]      E3 = ret['GPSInfo'][4][2][0]      E=int(E1)+int(E2)*(1.0/60)+int(E3)*(1.0/360000)      out.write(str(N)+','+str(E)+'\n')  except:   passout.close()

PS：Python小列子-读取照片位置

Python exifread

Python利用exifread库来解析照片的经纬度，对接百度地图API显示拍摄地点。
