Abstract
A distance measuring device includes a light emitting unit, a light receiving array unit, a signal intensity calculation unit, a signal time calculation unit, an intensity correction unit, and a distance calculation unit. The light emitting unit emits pulsed signal light. The light receiving array unit includes a plurality of photodetectors, each of which outputs a pulse signal in response to incidence of a photon. The signal intensity calculation unit calculates a signal intensity that indicates a light intensity of the signal light received by the light receiving array unit. The signal time calculation unit calculates a rise time and a fall time of the signal light detected by the light receiving array unit. The intensity correction unit corrects at least one of the rise time and the fall time calculated by the signal time calculation unit based on the signal intensity calculated by the signal intensity calculation unit.
