DJI-srt2xml

Split videos from a DJI-drone into individual images and create a .xml-file in the PASCAL VOC format for each of them from the .SRT-logfile

Usage:

python main.py --base_path_input example_videos/ --base_path_output example_images/ --frame_step 10

  • --base_path_input: Path to the .mp4-videos and .SRT-logfiles sorted in subfolders (e.g. by shooting date)

  • Example folder-structure:

    --example_videos/
  |-- subfolder1/ (e.g. shooting date)
      -- 1_visual.mp4  ("normal" video)
      -- 1_visual.SRT  (logfile)
      -- 1_thermal.mp4 (thermal video)
      -- 1_thermal.SRT (logfile)
      -- ...

  • base_path_output: Output path: images and xml-files will be sorted into subfolders:

    -- example_images/
   |-- images/                (images from "normal" video)
   |   |-- subfolder1/        (e.g. shooting date)
   |       |-- 1_visual/      (individual video)
   |           -- *.jpg       (list of images)
   |-- annotations/           (xml-files from "normal" video)
   |   |-- subfolder1/        (e.g. shooting date)
   |       |-- 1_visual/      (individual video)
   |           -- *.xml       (list of xml-files)
   |-- images_thermal/        (images from thermal video)
   |   |-- subfolder1/        (e.g. shooting date)
   |       |-- 1_thermal/     (individual video)
   |           -- *.jpg       (list of images)
   |-- annotations_thermal/   (xml-files from thermal video)
       |-- subfolder1/        (e.g. shooting date)
           |-- 1_thermal/     (individual video)
               -- *.xml       (list of xml-files)

  • Works with https://github.com/AlexanderLeipnitz/Online-Image-Annotator to annotate the images with bounding boxes or polygons

  • The folder-structure and xml-format is compatible between both projects

  • frame_step: frame-steps to extract a frame from the video and save it (e.g. 10 for every tenth frame)
