LASER RADAR DEVICE AND OBJECT DETECTING METHOD

摘要

A laser radar device disclosed herein includes a projector configured to project a laser beam to a predetermined monitoring area, a vertical direction beam receiver configured to receive reflected beam of the laser beam, the vertical direction beam receiver including predetermined numbers of dead zones and sensing zones disposed alternately in a vertical direction, and including in the vertical direction a plurality of resolutions configured, a peak detector configured to detect a peak of a received beam level of each of the reflected beams received by the sensing zones, and an object detector configured to calculate a distance to an object per sensing zone using the peak. The object detector recognizes that the object having a predetermined height is detected when continuously recognizing the distance calculated per sensing zone as the same distance for a predetermined number of times or more.
