Introduction

LiGuard is a research-purposed framework for LiDAR (and corresponding image) data. It provides an easy-to-use graphical user interface (GUI) that helps researchers interactively create algorithms by allowing them to dynamically create, enable or disable components, adjust parameters, and instantly visualize results.

LiGuard features, out of the box, data reading for many common dataset formats including support for reading calibration and label data. Moreover, it provides (an increasing list of) commonly used algorithm components ranging from basic data preprocessors to advanced object detection and tracking algorithms. Additionally, it establishes a straightforward standard for adding custom functions/algorithms, allowing users to integrate unique components into their pipelines. Pipelines created in LiGuard are saved in structured directories, making it easy to share and reproduce results.

Installation

Requirements:

• Windows 10 or later
• Python 3.8, 3.9, 3.10, or 3.11

Install LiGuard with pip (from PyPI):

pip install LiGuard

Run LiGuard by executing the following command in the terminal:

liguard-gui

Usage

Test an example pipeline:

1. In the Configuration windows, click the Open button.
2. Navigate to examples/simple_pipeline, click open, and then click Apply.
3. Explore various functions under proc dropdown in the Configuration window. For example, under proc/lidar/crop, check the enabled checkbox, and click Apply to see the cropped LIDAR data.
4. Press left arrow or right arrow to navigate through the frames. A list of all key bindings is available here.
5. To save the pipeline, click the Save button in the Configuration window.

For more details on pipelines, see LiGuard Pipelines.
