我正在使用以下代码提取使用iPhone拍摄的图像的地理位置信息:
from PIL import Image
from PIL.ExifTags import TAGS
def get_exif(fn):
ret = {}
i = Image.open(fn)
info = i._getexif()
for tag, value in info.items():
decoded = TAGS.get(tag, tag)
ret[decoded] = value
return ret
a = get_exif('photo2.jpg')
print a
这是我得到的结果:

我想知道如何将GPSInfo值(DMS)转换为实际坐标的十进制度数?另外,似乎有两个西经方向的列表...?
