Abstract
A laser radar irradiates electromagnetic waves around a subject vehicle, detects the electromagnetic waves reflected from objects lying around the subject vehicle, and outputs a plurality of directions of scanning irradiation and detected distances from the subject vehicle to the objects in the respective directions. A recognition unit detects a relative position and relative speed of each objects lying around the subject vehicle. The recognition unit stores whether or not detection points data exists in each of M×N small regions into which X, Y coordinates are divided into a two dimensional array including a plurality of elements corresponding to the small regions. The recognition unit performs arithmetic operations of multiplication and summation of the respective elements of the two dimensional array while sequentially scanning a mask of a two dimensional array comprising J×K (J<N, K<M) elements, and determines attributes such as positions, sizes, etc. of the objects.
