Abstract:
A distance measuring device according to an embodiment includes a weight value generator, a cumulative signal generator, and a distance measurer. The weight value generator generates, on the basis of similarity between a first digital signal obtained by digitizing reflected light of laser light irradiated in a first irradiation direction and a second digital signal obtained by digitizing reflected light of laser light irradiated in a second irradiation direction different from the first irradiation direction, a weight value of the second digital signal. The cumulative signal generator accumulates, on the first digital signal, a signal obtained by weighting the second digital signal with the weight value and generates a third digital signal. The distance measurer measures a distance to a target object on the basis of a time difference between irradiation timing of the laser light and timing of a peak position in the third digital signal.

Claim (Index 5):
The distance measuring device according to  claim 1 , wherein\n the weight value generator includes: a first cumulative value calculator configured to calculate a first cumulative value obtained by accumulating, within a predetermined period, a plurality of the first digital signals obtained by respectively digitizing reflected lights of the laser light intermittently irradiated in the first irradiation direction; a second cumulative value calculator configured to calculate a second cumulative value obtained by accumulating, within the predetermined period, a plurality of the second digital signals obtained by respectively digitizing reflected lights of the laser light intermittently irradiated in the second irradiation direction; a first ratio calculator configured to calculate a first ratio of the first cumulative value and the second cumulative value; a first peak value detector configured to detect a first peak value at which signal amplitude of the first digital signal is maximized or minimized; a second peak value detector configured to detect a second peak value at which signal amplitude of the second digital signal is maximized or minimized; and a second ratio calculator configured to calculate a second ratio of the first peak value and the second peak value, and the weight value generator generates the weight value of the second digital signal on the basis of the first ratio and the second ratio.
