Hi, I am trying to work on a project to make a 3d map of a room using Kinect 360 and Rplidar A1 sensor as shown in this video https://www.youtube.com/watch?v=MlrcTyXy5No. I am able to create 2D mapping using RViz and 3D map using RTABmap but unable to integrate them both to generate as shown in video. The github link in video does not specify what is to be done. I am new to both RPLiDAR and Kinect 360 and do not have full understanding of ROS. Can anybody give me instructions on how to work on it?
