Claim 0:
1. An external environment recognition device that recognizes an external environment of an autonomous mobile object, the external environment recognition device comprising:
a plurality of external environment recognition sensors each having an information detection circuit that detects information of an object outside the autonomous mobile object, the plurality of external environment recognition sensors being arranged such that a detection range of the information detection circuit includes an overlapping region where at least part of the detection range of the information detection circuit overlaps with at least part of the detection range of another one of the information detection circuits; and
a synchronous processing circuit that extracts identical objects in the overlapping region from detection results of the external environment recognition sensors, performs no synchronous processing if there is no deviation in position between the identical objects in the overlapping region, and performs synchronous processing to synchronize the plurality of external environment recognition sensors a timing when a deviation in position between the identical objects in the overlapping region occurs, wherein
the plurality of external environment recognition sensors include a plurality of cameras arranged so as to have the overlapping region, and
the synchronous processing circuit extracts identical objects from images in the overlapping region of the plurality of cameras, identifies static objects from among the identical objects, and superimposes the static objects on each other to determine whether or not there is a deviation in position between the identical objects.
