<P>PROBLEM TO BE SOLVED: To accurately perform determination of a pedestrian even with change of the pedestrian's state or various environmental conditions. <P>SOLUTION: A control unit 3 performs detection of pedestrian by performing pattern matching processing to images taken by a pair of infrared cameras 4 using a plurality of preliminarily prepared model images. Specifically, when it is raining, or when an atmospheric temperature of a threshold or lower is determined, an object is determined to be the pedestrian if matching with the model image of pattern A is successful. When it is not raining, the atmospheric temperature is higher than the threshold, and the current time is out of a set time zone, the object is determined to be the pedestrian if matching with any one of the patterns A, C and E is successful. Further, when it is not raining, the outside air temperature is higher than the threshold, and the current time is within the set time zone, the object is determined to be the pedestrian if matching with any one of the patterns B, D and F is successful. <P>COPYRIGHT: (C)2007,JPO&INPIT |
