OVERVIEW
The YDLIDAR G4 Lidar is a 360-degree two-dimensional distance measurement product
(hereinafter referred to as G4) developed by the YDLIDAR team. This product is based on the
principle of triangulation, and is equipped with relevant optics, electricity, and algorithm design to
realize high-frequency and high-precision distance measurement. At the same time as the distance
measurement, 360 degrees of scanning distance measurement is achieved by continuously obtaining
the angle information through the 360 degree rotation of the motor.
