摘要：A vehicle environment monitoring apparatus capable of extracting an image of amonitored object in an environment around a vehicle by separating the same from thebackground image with a simple configuration having a single camera mounted on thevehicle is provided. The apparatus includes a first image portion extracting processing

unit to extract first image portions (A, A) considered to be the head of a pedestrian froma currently picked up image and a previously picked up image by an infrared camera, amask area setting processing unit to set mask areas (M(0,0), M(1,0), . . . , M(5,8)) aroundthe first image portion (A) in the currently picked up image, and an object extractingprocessing unit to carry out pattern matching for the previously picked up image by acomparison pattern obtained through affine transformation of each mask area at achange rate (Rate) between the first image portions (A, A), and to set an area (Ar)including the first image portion (A) and a second image portion (M(1,3), M(2,3), . . . ,M(3,6)) where a displacement amount between the position (black point) correspondingto the centroid of the mask area and the matching position is smaller than apredetermined threshold value to be an image area of the monitored object.
