The present invention relates to an apparatus for detecting two-direction distances. The apparatus for detecting two-direction distances according to an embodiment of the present invention comprises: a sensor module which includes a light emitting unit which emits a first wavelength beam and a second wavelength beam, a light receiving unit which receives reflectedion light emitted by the light emitting unit and reflected and returned from an object, and first and second splitters which are disposed in front of the light emitting unit and the light receiving unit, which allow the first wavelength beam to pass, and reflects the second wavelength beam; and a motor which rotates the sensor module. The sensor module alternately emits the first wavelength beam and the second wavelength beam at predetermined time intervals, and measures a first direction distance and a second direction distance. The apparatus further comprises a cover for protecting the sensor module, and the cover is provided with a holder for fixing the first and second beam splitters. The apparatus for detecting two-direction distances is provided with wheels, and is mounted and operated on a system which moves with respect to a bottom. Accordingly, distance measurement and height measurement have to be performed by one module, and thus it is possible to reduce manufacturing costs. |
