    The present invention relates to an apparatus and a method for calculating the distance and angle between vehicles. According to an embodiment of the present invention, the apparatus for calculating the distance and angle between vehicles comprises: a pattern interval calculation unit which photographs a first pattern which is irradiated by a first light-emitting module mounted on a preceding vehicle, and a second pattern which is irradiated by a second light-emitting module to be apart from the first pattern by a first interval of a photograph or a video to calculate a second interval between the first pattern and second pattern within the photograph or the video photographed; a lookup table storage unit which stores the second interval with the first interval as a reference, an estimated value of the distance from the preceding vehicle in accordance with the second interval, and an estimated value of the angle forming the estimated value of the distance; and a distance and angle calculation unit which extracts the estimated value of the distance from the preceding vehicle and the estimated value of the angle forming the estimated value of the distance from the lookup table storage unit in accordance with the second interval calculated by the pattern interval calculation unit used to calculate the distance and angle from the preceding vehicle. The present invention aims to provide an apparatus and method for calculating the distance and angle between vehicles, which are able to precisely calculate the distance and angle from neighboring vehicles and realize safe autonomous driving.
