ENVIRONMENTAL COMPLEXITY ARITHMETIC SYSTEM, ENVIRONMENTAL RECOGNITION LEVEL ESTIMATION SYSTEM AND OBSTRUCTION WARNING SYSTEM

摘要

PROBLEM TO BE SOLVED: To support obstruction recognition efficiently and accurately without presenting a driver with excessive information. SOLUTION: A microcomputer 70 divides a pickup image produced by an obstruction imaging CCD camera 21 into regions A to D, and computes complexity C of traffic environment in each of the regions B to D according to the following expression: C=α.C1+β.C2+γ.C1.C2, where the index C1 represents a total number of brightness-divided blocks, the index C2 represents a total number of red-system-divided blocks, andα,βandγare weight coefficients of respective given values.
