Abstract
One embodiment includes: A laser range finder that obtains a distance to an object and a light-reception level of reflected light: a scanning mechanism that changes the measurement direction; a data acquiring portion that periodically performs measurement while changing the measurement direction; a data correcting portion that removes distance information of a portion corresponding to a discontinuous change and corrects light-reception level information of a portion that does not correspond to the discontinuous change after the obtained distance information and light-reception level information are compared with distance information and light-reception level information of preceding and succeeding measurement periods in each direction; a human body judging portion that extracts a portion that is presumed to correspond to a human body, and judges whether or not the extracted portion matches a human body based on a time-series moving status of the extracted portion; and an alert output control portion.
