Abstract

A distance measuring apparatus includes: a plurality of two-dimensional scanning laser sensors; and a control circuit configured to control the plurality of two-dimensional scanning laser sensors, wherein each of the two-dimensional scanning laser sensors includes a light projection system configured to project laser light for scanning a measurement target, and a light reception system configured to outputs a signal corresponding to a distance to the measurement target by using a multi-division light receiving element configured to receive return light of the laser light reflected by the measurement target, and the control circuit is configured to synchronize a scanning timing of the laser light projected by a light projection system of each of adjacent two-dimensional scanning laser sensors among the plurality of two-dimensional scanning laser sensors, and cause the adjacent two-dimensional scanning laser sensors to horizontally scan the laser light in a direction opposite from each other.
