Title:

VEHICLE VICINITY MONITORING APPARATUS

Document Type and Number:

Japanese Patent JP3934119

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a vehicle vicinity monitoring apparatus which can recognize a pedestrian by accurately determining a binarizing target of an unfixed shape extracted from an infrared image.
SOLUTION: When recognizing a pedestrian from the presence of his legs, if a width WB of a binarizing target 100 in a real space is appropriate as the legs of the walker, the binarizing target 100 has a longitudinally long shape, a lower end of the binarizing target 100 is positioned in a lower part (lower half) of a gray scale target area 101 and there is a time sequential luminance change in the binarizing target 100, the binarizing target 100 is recognized as a pedestrian. When recognizing a pedestrian from the presence of an umbrella held by the pedestrian, on the other hand, if a lateral width of an umbrella area 104 is appropriate as the pedestrian's umbrella and further, a positional relationship between the coordinates of the position of a center of gravity for the umbrella area 104 and coordinates of the position of a center of gravity for the binarizing target 100 is appropriate as a positional relationship between the pedestrian and his umbrella, the binarizing target 100 is recognized as a pedestrian.
