3D LiDAR point cloud annotation

Hello everyone, I'm working on an object detection algorithm from LiDAR data. The goal of the project is to train a deep learning model to detect traffic cones and output their bounding boxes. I've decided I want to make my own data set and for that I need to somehow annotate a lot of point cloud frames.

I saw few web tools out there for the task, but I am looking for something free (I am an undergrad student so …
