OVERVIEW YDLIDAR G4 is a 360-degree two-dimensional rangefinder (hereinafter referred to as G4) developed by YDLIDAR team. Based on the principle of triangulation, it is equipped with related optics, electricity, and algorithm design to achieve high-frequency and high-precision distance measurement. The mechanical structure rotates 360 degrees to continuously output the angle information as well as the point cloud data of the scanning environment while ranging.
