Python EXIF无法找到日期信息,但在通过Windows属性查看器时存在 [英] Python EXIF can't find date taken information, but exists when viewer through windows properties
问题描述
我需要按拍摄日期提取和整理照片. Windows 10,Python 2.7.我一直在做
I need to extract and organize photos by date taken. Windows 10, Python 2.7. I had been doing this
from PIL import Image
def get_date_taken(path):
return Image.open(path)._getexif()[36867]
以下:
对于某些照片来说效果很好.
and that works great for some photos.
太好了.现在,在获取另一组图像(新相机)后,属性看起来相似.
Great. Now grabbing a different set of images, new camera, the properties look similar.
但是字典完全不同
Image.open(image)._getexif()[36867]
Traceback (most recent call last):
Debug Probe, prompt 369, line 1
KeyError: 36867
Image.open(image)._getexif()
{36864: '0220', 37121: '\x01\x02\x03\x00', 40962: 2048, 40963: 1536, 40960: '0100', 40961: 1, 296: 2, 34665: 90, 34855: 1600, 531: 2, 282: (72, 1), 283: (72, 1), 37500: '\x01\xf1\x03\x00\x03\x00\x00\x00\x11 ....
我也尝试过exifread
I tried exifread too
a=exifread.process_file(open(image,'rb'))
a.keys()
['EXIF MakerNote', 'Image ExifOffset', 'EXIF ExposureTime', 'EXIF ComponentsConfiguration', 'Image YCbCrPositioning', 'Image XResolution', 'EXIF FlashPixVersion', 'EXIF ISOSpeedRatings', 'Image YResolution', 'EXIF ColorSpace', 'EXIF ExifImageLength', 'EXIF ExifVersion', 'Image ResolutionUnit', 'EXIF ExifImageWidth']
但没有日期. Windows在读什么不是python的东西?关于其他尝试的任何建议,我是否需要担心跨平台?与此处相同的问题:
but no date taken. What is windows reading that python isn't? Any suggestions on what else to try, do I need to worry cross platform? Same question as here:
" ;日期:在Windows资源管理器中的文件详细信息(文件属性)中显示时,没有出现在Image PropertyItems中
但在python中.这个友好的在线元数据查看器
but in python. This friendly online metadata viewer

建议两个图像在exif中都有创建日期的标签.还有什么办法访问它们?
suggests both images have date created tags in exif. How else to access them?

推荐答案
我是使用exifread库完成的.这是我的python代码的片段.
I did it using the exifread library. Here is a snippet of my python code.
import exifread
for filename in os.listdir(directoryInput):
if filename.endswith('.JPG'):
with open("%s/%s" % (directoryInput, filename), 'rb') as image: # file path and name
exif = exifread.process_file(image)
dt = str(exif['EXIF DateTimeOriginal']) # might be different
# segment string dt into date and time
day, dtime = dt.split(" ", 1)
# segment time into hour, minute, second
hour, minute, second = dtime.split(":", 2)
