[Feature] Add support for the command line interface

[holtvogt]

Feature Description

Add a CLI to the tracklet-parser package to allow users to parse tracklet XML files and convert them to KITTI format directly from the terminal. The CLI should use argparse for argument parsing and provide options for specifying the input XML file, frame list, and output directory.

Use Case

As some users might want to automate the steps to create label files, it would be handy to execute the tracklet parser via the command line with arguments.

Proposed Solution

1. Add a cli.py module to handle CLI logic.
2. Allow users to run the package via python -m tracklet_parser or a CLI entry point.
3. Provide the following arguments:
   • --labels: Path to the tracklet XML file (required).
   • --frames: Path to the frame list file (optional).
   • --outputs: Directory to save KITTI format files (default: output).

Additional Context

Example usage:

python -m tracklet_parser --labels path/to/tracklet_labels.xml --frames path/to/frame_list.txt --output path/to/output_dir

Hi,

Thanks for the tool.

As I saw in the git library of the tracklet_parser, these is no file named parser.py.

Is it the file named tracklet_parser.py in the "https://github.com/holtvogt/tracklet_parser/tree/develop/tracklet_parser" directory which is to be used to run it from the command line?

Best Regards,
Ajay

It is not implemented yet, thus there is indeed no file named parser.py. It was an idea I wanted to capture when I worked on it during my bachelor thesis to simplify the parsing process. I haven't worked on it since. It should basically add the ArgumentParser so that the TrackletParser can be used from CLI. But as I will be fixing #4 , I might implement it straight away :D

Thanks for the response @holtvogt.
