Intro
(LiDAR Light Detection and Ranging)
LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser light to measure distances to objects. It works by emitting laser pulses and measuring the time it takes for the light to bounce back after hitting an object. Based on this time and the speed of light, the LiDAR system calculates the distance to the object, generating a detailed 3D map of the environment.
Slamtec- RPLIDAR A1
RPLIDAR A1 is a low cost 360 degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. The system can perform 360 degree scan within 12-meter range. The produced 2D point cloud data can be used in mapping, localization and object/environment modeling.
RPLIDAR A1’s scanning frequency reached 5.5 hz when sampling 1450 points each round. And it can be configured up to 10 hz maximum. RPLIDAR A1 is basically a laser triangulation measurement system. It can work excellent in all kinds of indoor environment and outdoor environment without direct sunlight exposure. https://www.dfrobot.com/product-1125.html
