摘要： A device for monitoring surroundings of a vehicle mounted in a vehicle, captures an image of surroundings of the vehicle, extracts from the captured image an image area for a predetermined part of a desired type of object, and sets a predetermined area below the extracted image area. The device extracts candidates for the desired type of object present outside the vehicle based on the predetermined area and determines, for each of the extracted object candidates, whether the object candidate is the desired type of object. When no pattern different from the background is captured in the predetermined area, or when a pattern different from the background is captured only in one of a first and a second areas, then the object in the image area is excluded from the candidates for the desired type of object. Thus, a pedestrian, for example, can be distinguished from an artificial structure.

摘要： The present invention provides an automotive environment monitoring device to detect the existence of an object, a pedestrian or the like, with high accuracy even if one part of the object is overlapped with the background of an image obtained from an imaging unit mounted on the vehicle. An area where the object exists in the image obtained from an infrared camera (102) is set as a first area (A1i) and a lower portion of the first area (A1i) is set as a second area (A2i). A feature of the object is extracted with respect to the second area (A2i) and the object is identified based on the extracted feature. Thereby, even in the case where the first area (A1i) has been set but the feature of an upper part of the object can not be extracted due to the upper part of the object being overlapped with the background of the image, the object can still be identified with high accuracy by extracting the feature of a lower part of the object in the second area (A2i).

摘要： An imaging means mounted on a vehicle performs imaging resulting in grayscale images having brightness values corresponding to object temperature, and objects around the vehicle are detected from said images. On the basis of said grayscale images, display images to be displayed on a display device mounted on the vehicle are generated and displayed on the display device. The display images are generated by lowering the brightness of areas not corresponding to the objects detected in the grayscale images. The display device is positioned in the vehicle width direction at no more than a prescribed distance away from an imaginary line passing through the center of rotation of the vehicle steering wheel and extending in the longitudinal direction of the vehicle. Accordingly, because display images are generated in which only the objects are spotlighted, the driver can quickly comprehend the objects present when using a display device.
