Abstract
A near-infrared night vision device to which a pedestrian detection device is applied includes a near-infrared projector, a near-infrared camera, a display and an ECU. By executing programs, the ECU constitutes a pedestrian candidate extraction portion and a determination portion. The pedestrian candidate extraction portion extracts pedestrian candidate regions from near-infrared images. The determination portion normalizes the sizes and the brightnesses of the pedestrian candidates extracted by the pedestrian candidate extraction portion, and then computes the degrees of similarity between the normalized pedestrian candidates. The determination portion determines that a pedestrian candidate having two or more other pedestrian candidates whose degree of similarity with the pedestrian candidate is greater than or equal to a predetermined value is not a pedestrian.

6. A pedestrian detection method comprising:
-
extracting a pedestrian candidate from a picked-up image; and finding a degree of similarity between pedestrian candidates, and determining that a pedestrian candidate whose degree of similarity with another pedestrian candidate is greater than or equal to a predetermined value is not a pedestrian, when a plurality of pedestrian candidates are extracted by extraction of the pedestrian candidate.

7. A pedestrian detection device comprising:
-
pedestrian candidate extraction portion that extracts a pedestrian candidate from a picked-up image; and determination portion that finds a degree of similarity between pedestrian candidates if a plurality of pedestrian candidates are extracted by the pedestrian candidate extraction portion, and that determines that a pedestrian candidate whose degree of similarity with another pedestrian candidate is greater than or equal to a predetermined value is not a pedestrian. - View Dependent Claims (2, 3, 4, 5)
