LAMP SYSTEM CAPABLE OF DETECTING STEREOSCOPIC SHAPE OF ROAD SURFACE

A lamp system capable of detecting a stereoscopic shape of a road surface includes: a light projecting device including a light source that generates patterned light having a specific pattern and projects the patterned light onto a projection surface; a sensor unit including a camera that captures a pattern in which the patterned light is projected onto the projection surface to provide an image of the projection surface; and a control unit that determines a three-dimensional shape of the projection surface based on an output of the sensor unit, and controls an output of the light projecting device according to the determined three-dimensional shape of the projection surface.
