Object identification using rajer and identifying object using the same

摘要

The present invention relates to an object recognition system using a laser for recognizing an object through a laser beam reflected by irradiating a laser and estimating the size of the recognized object, and an object recognition method using the same. The object recognition system according to the present invention includes a light source unit that irradiates a laser beam, an optical deflector that changes the direction of a laser beam irradiated from the light source to be irradiated at different positions over time, and a laser beam irradiated through the optical deflector meets an object. And a control unit configured to recognize an object through a laser beam reflected from the photodetector, and estimate a size of the object through an angle at which the reflected laser beam detected from the photodetector is changed.
