Abstract

See full text

A distance information acquisition device includes: a light emitter which emits light according to an emission pulse indicating emission; a solid-state imaging element which performs exposure according to an exposure pulse indicating exposure; an emission/exposure controller which generates a timing signal indicating a plurality of pairs of the emission pulse and the exposure pulse having a time difference that is different in each of the plurality of pairs; and a multipath detector which obtains a sequence of received light signals from the solid-state imaging element by the emission and the exposure that correspond to each of the plurality of pairs, compares the obtained sequence of received light signals and reference data created in advance as a model of a sequence of received light signals in a multipath-free environment, and determines the presence or absence of multipath according to a difference in a comparison result.
