# PedX

This package provides basic tools for working with the PedX dataset [[1]](#references) in Python.

## Data
The dataset is available from the webpage (http://pedx.io/downloads/). You can download the entire dataset by running the script `download_data.py`.  The data will be organized as in the following directory tree.

```

* `data` contains the rectified images, point clouds, calibrated parameters and frame metadata.
* All the manual/automatic annotations are in `data/labels`. 2D/3D annotations are provided in an instance-level.
* We provide 3 video sequences captured at different 4-way stop intersections on different dates.
	* Capture dates: `20171130T2000`, `20171207T2024`, `20171212T2030`
* The cameras are color-coded for our convenience.
	* Cameras: `ylw79D0`, `red707B`, `blu79CF`, `grn43E3`
	* Stereo pairs: `ylw79D0-red707B`, `blu79CF-grn43E3` (left-right camera)
* We provide a simple Python demo script: `demo.py`. `pedx` provides Python helper functions to load and visualize the data. We have tested the script with the Python packages listed in `requirements.txt`.
