ABSTRACT:
A vehicle surroundings monitoring apparatus capable of recognizing the type of object existing around a vehicle with accuracy. The vehicle surroundings monitoring apparatus includes a process unit, which extracts a first image portion HP—1likely to be the head of an object and sets a reference mask area MASK_C including HP—1, a left-hand mask area MASK_L near the left side of the reference mask area MASK_C, and a right-hand mask area MASK_R near the right side of the reference mask area MASK_C, and a process unit which searches for a second image portion presumed to be a leg image within a lower search area AREA—3when a difference between an average luminance AVE_C of the reference mask area MASK_C and an average luminance AVE_L of the left-hand mask area MASK_L or a difference between the average luminance AVE_C and an average luminance AVE_R of the right-hand mask area MASK_R is equal to or greater than a predetermined level and which recognizes that the object type is “pedestrian” in the case where a plurality of second image portions are detected.
