Abstract
Disclosed herein is a distance measuring apparatus. The distance measuring apparatus includes a light-emitting unit configured to radiate light in a pulse form of a specific width, a light-receiving unit configured to include a plurality of cells for receiving reflected light radiated by the light-emitting unit and reflected by an object, and a processor configured to perform one or more of an operation for calculating a first distance of the object using a first method based on the locations of one or more cells which belong to the plurality of cells and on which the reflected light is focused and an operation for calculating a second distance of the object using a second method based on the time when the reflected light is reached and to correct the first distance calculated using the first method based on the second distance calculated using the second method.
