PROBLEM TO BE SOLVED: To accurately recognize environment even when objects small in the difference of distance exist. SOLUTION: Even when plural objects 11 and 12 partially coming close to each other exist, the existence of the individual objects frequently appears as a separate peak in frequency distribution (peak-D and peak-E) in the case the average distances of the individual objects are different. By taking notice of this point, the frequency distribution of the information is made based on the information on the distance distribution of field space and area dividison is performed based on the information on the frequency distribution. |
