VEHICLE-MOUNTABLE DISTANCE MEASUREMENT DEVICE

摘要

A vehicle-mountable distance measurement device is mountable in a vehicle and measures a distance from an object existing in surroundings. The vehicle-mountable distance measurement device includes: a light projection unit which projects measurement light in which a two-dimensional predetermined pattern specific to the vehicle is repeated; a light receiving unit including a plurality of light receiving elements which are arranged in a two-dimensional manner and which output light receiving signals in response to reception of light; and a distance detection unit which calculates the distance from the object based on a time when the light projection unit projects light and a time when the light receiving unit receives light. The distance detection unit calculates the distance from the object based on the time when the light receiving unit receives the measurement light having the predetermined pattern projected by the light projection unit.
