LiDAR is the abbreviation of Light Detection and Ranging, which is the distance measurement method utilizing remote sensing (detecting a sensor at a remote location) where near-infrared light, visible light and ultraviolet light are illuminated on an object, and the reflected light is detected through an optical sensor. It is also known as Laser Imaging Detection and Ranging, which refers to the method of measuring the time difference between a pulsed near-infrared laser illuminated on an object and laser light reflected on an object surface.
LiDAR is capable of not only measuring the distance to an object, but is also capable of precisely detecting an object’s location and shape.
