DISTANCE MEASURING APPARATUS, DISTANCE MEASURING METHOD, AND CONTROL PROGRAM

摘要

According to an embodiment, a distance measuring apparatus includes a multi laser beam emitting unit, an irradiating position changing unit, an image acquiring unit, and a distance calculating unit. The multi laser beam emitting unit irradiates a surface of a measurement target object with a plurality of elliptical laser beams provided in line in a minor axis direction. The irradiating position changing unit reciprocally moves irradiating positions of the laser beams all together along a major axis of the laser beams. The image acquiring unit receives reflected lights of the laser beams, and acquires an image of a bright and dark pattern of the reflected lights of the laser beams formed on an image acquiring face. The distance calculating unit calculates a distance to the measurement target object based on the bright and dark pattern of the reflected lights on the image acquiring face.
