python解析拍摄时间

引言

手机中拍摄照的照片和视频快爆了，想转移到PC端，并按时间建立文件夹存储到电脑中，本文主要介绍如何通过python获取手机拍摄图片的时间信息并存储。

1. 获取图片拍摄时间

首先需要安装exifread库。通过EXIF(Exchangeable image file format: 可交换图像文件格式) 获取这些信息。

获取图片时间信息：

import exifread
with open(file_path, 'rb') as file_data:
    tags = exifread.process_file(file_data)
    tag_date = 'EXIF DateTimeOriginal'
    if tag_date in tags:
        file_rename =str(tags[tag_date]).replace(':','').replace(' ', '_') + os.path.splitext(filename)[1]
        new_path = os.path.join(root_dir, file_rename)
        os.rename(file_path, new_path）

通过以上代码即可获取拍摄时间，得到时间格式：2022:03:11 11:30:06

我们将文件重命名，方便后续管理。

2. 获取视频拍摄时间

获取视频拍摄时间信息：

    format = '%Y%m%d_%H%M%S'
    file_path = os.path.join(root_dir, filename)
    statinfo = os.stat(file_path)
    temp_time = time.localtime(statinfo.st_mtime)
    file_rename = str(time.strftime(format, temp_time)) + os.path.splitext(filename)[1]
    new_path = os.path.join(root_dir, file_rename)
    os.rename(file_path, new_path)

同样我们将文件重命名，方便后续管理。

3. 根据图片时间建立文件夹

通过以上操作，照片和视频文件我们都以时间格式进行命名。接下来我们根据时间建立文件夹整理。

time_info =  os.path.splitext(filename)[0].split("_")[0]
dst_dir = save_dir + time_info
if not os.path.exists(dst_dir):
    os.mkdir(dst_dir)
src_path = os.path.join(root_dir, filename)
save_path = os.path.join(dst_dir, filename)
shutil.move(src_path, save_path)

            if tag_date in tags:
                file_rename = str(tags[tag_date]).replace(':', '').replace(' ', '_') + os.path.splitext(filename)[1]
                new_path = os.path.join(root_dir, file_rename)
                print(file_path,new_path)
                os.rename(file_path, new_path)
            else:
                print('No {} found'.format(tag_date), ' in: ', file_path)

                rename_pic(root_dir, filename)
            elif re.search(video_reg, filename):
                rename_video(root_dir, filename)
def save_files(root_dir, save_dir):
    for filename in os.listdir(root_dir):
        try:

            shutil.move(src_path, save_path)
        except Exception as e:
            print("error ", e)
if __name__ == '__main__':
    root_dir = "/Users/xxx/pics"
    save_dir = "/Users/xxx/Downloads/"
    rename(root_dir)
    save_files(root_dir, save_dir)
