LiDAR (light detection and ranging) technology offers accurate 3D mapping and has become more affordable and accessible in recent years.
It has many applications, including in self-driving cars and small robots and is expected to become more common.
A software suite has been developed for the Raspberry Pi to offer a custom serial driver and scanning system for LiDAR modules, and includes features such as real-time 2D visualisation, vertex colour extraction, the ability to generate 360-degree panoramic maps using fisheye camera images, and export capabilities for integration with other tools.
It can use a stepper motor for quick full-area scanning and power options including a USB battery bank or a pair of 18650 lithium cells, making the system portable and self-contained during scans.
