Abstract
A distance measuring apparatus according to an embodiment of the present disclosure includes a light-receiving unit, a histogram acquiring unit, and an operation unit. The light-receiving unit receives reflected light from a distance measurement target. The reflected light is based on irradiation light from a light-emitting unit. The histogram acquiring unit acquires a histogram indicating the frequency of reception of the reflected light at the light-receiving unit. The operation unit calculates a distance to the distance measurement target on the basis of a time corresponding to a peak of the histogram acquired by the histogram acquiring unit. The operation unit corrects the distance calculated on the basis of the time corresponding to the peak of the histogram on the basis of the shape of the histogram acquired by the histogram acquiring unit.
