• 💥 L-CAS 3D Point Cloud Annotation Tool 2️⃣ is released. 💥

L-CAS 3D Point Cloud Annotation Tool

• Maintainer status: maintained
• Author: Zhi Yan
• License: GPL-3.0
• Dataset: https://lcas.lincoln.ac.uk/wp/research/data-sets-software/l-cas-3d-point-cloud-people-dataset/

The tool provides a semi-automatic labeling function, means the 3D point cloud data (loaded from the PCD file) is first clustered to provide candidates for labeling, each candidate being a point cluster. Then, the user annotating the data, can label each object by indicating candidate's ID, category, and visibility. A flowchart of this process is shown below.

The quickest way to activate the optional steps is to modify the source code and recompile. 😱

Compiling (tested on Ubuntu 14.04/16.04)
