Title:
DISTANCE MEASURING DEVICE, AND MOBILE BODY
Document Type and Number:
WIPO Patent Application WO/2020/039916
Kind Code:
A1
Abstract:
This distance measuring device comprises: a plurality of distance measuring units; a measuring unit; a scanning control unit; and a determination unit. The distance measuring units have a light radiating part for radiating a laser beam to outside, a light receiving part for receiving reflected light of the laser beam, and a scanning mechanism for scanning the laser beam in a rotational direction. The scanning control unit controls the driving of the scanning mechanism of each of the distance measuring units, and causes the laser beams of the respective distance measuring units to each be radiated in different directions. The measuring unit calculates a relative position of an external object on the basis of the radiation timings and the radiation directions of the laser beams, and the light receiving results of the light receiving parts. The determination unit determines whether the object is actually present at the relative position on the basis of results from comparing the relative positions calculated by the respective distance measuring units.
