Visualizing lidar data

Visualizing lidar data using Uber Autonomous Visualization System (AVS) and a Jupyter Notebook Application

This project contains two different applications for visualizing lidar data using KITTI Vision Benchmark Suite datasets.

1. Uber AVS Autonomous Visualization System (AVS) --- XVIZ (the data layer for AVS)

Quick start

You need Node.js and yarn to run the examples.

# Clone XVIZ
$ git clone https://github.com/uber/xviz.git
$ cd xviz

# Install dependencies
$ yarn bootstrap

Convert and serve KITTI example data:

# Download KITTI data
$ ./scripts/download-kitti-data.sh

# Convert KITTI data if necessary and run the XVIZ Server and Client
$ ./scripts/run-kitti-example.sh

2. KITTI Dataset Exploration

Dependencies

Apart from the common dependencies like numpy and matplotlib notebook requires pykitti. You can install pykitti via pip using:

pip install pykitti

Project structure

File	Description
`kitti-dataset.ipynb`	Jupyter Notebook with dataset visualisation routines and output.
`parseTrackletXML.py`	Methods for parsing tracklets (e.g. dataset labels), originally created by Christian Herdtweck.
`utilities.py`	Convenient logging routines.

I have used one of the raw datasets available on KITTI website.
