我正在使用以下代码来提取使用 iPhone 拍摄的图像的地理位置:
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
这是我返回的结果:
{
'YResolution': (4718592, 65536),
41986: 0,
41987: 0,
41990: 0,
'Make': 'Apple',
'Flash': 32,
'ResolutionUnit': 2,
'GPSInfo': {
1: 'N',
2: ((32, 1), (4571, 100), (0, 1)),
3: 'W',
4: ((117, 1), (878, 100), (0, 1)),
7: ((21, 1), (47, 1), (3712, 100))
},

}
所以,我想知道如何将 GPSInfo 值 (DMS) 转换为实际坐标的十进制度数?此外,似乎列出了两个 Wests。. . ?
