ABSTRACT:
A driving environment surveillance apparatus is provided to specify a region where an obstacle is present depending upon an azimuth detected by an obstacle detecting unit so as to derive a two-dimensional image corresponding to the specified region from an image detecting unit, and to extract the obstacle from the two-dimensional image so as to calculate a size index of the obstacle, thereby detecting a relative distance or the azimuth to the obstacle from a vehicle with high accuracy and at a high speed.
