THREE DIMENSION SPACE SENSING SYSTEM AND DRIVING METHOD THEREOF

摘要

PURPOSE: A 3D space sensing system and a driving method thereof are provided to reduce vibration and noise when the 3D space sensing system is vertically operated. CONSTITUTION: A 3D space sensing system comprises a rotating body(120), a reflector(110), a vertical operating link(150), a vertical motor(160), and a motor operating unit(170). The rotating body rotates on a central axis. The reflector has a structure rotatable on the diametrical central axis and is coupled to the upper part of the rotating body. The reflector reflects emission light and incident light through the inside of the rotating body. The vertical driving link moves one side of the reflector up and down to control the slope of the reflector. The vertical motor vertically lifts the vertical driving link to control the slope of the reflector. The motor driving unit increases or decreases the driving speed of the vertical motor in proportion to the moving distance of the vertical driving link.
