Abstract
A distance measurement device includes a light emitting and receiving units, and a calculation unit that uses a time-of-flight to calculate an object distance. The calculation unit includes: a histogram generation unit; a composite peak portion estimation unit that estimates whether a composite peak portion is present in a histogram, the composite peak portion being a peak portion at which the received light intensity changes with respect to the time-of-flight with reference to a peak time-of-flight and which is obtained from a combination of distributions of intensity of light from objects, differences of distances to the objects from the device being within a predetermined range; a time-of-flight specification unit that specifies rise time and fall time; a base time-of-flight determination unit that determines a base time-of-flight based on the rise time or the fall time; and a distance calculation unit that uses the base time-of-flight to calculate the object distance.
