Zusammenfassung: | To provide an object recognition device capable of recognizing an object while suppressing a processing load.SOLUTION: An object recognition device uses a ratio of a frequency distribution calculated by a first calculation part 51 and a frequency of a rank calculated by a second calculation part 52, for determining whether or not an object article is included in a recognition target region 41. A gradient intensity of luminance for every rank in a gradient direction of luminance in a division region 42 and a recognition target region 41 expresses a feature of the object article included in the recognition target region 41. Therefore, a ratio of a frequency of the rank also becomes a parameter for determining presence/absence of the object article. Therefore, presence/absence of the object article can be determined by using not only the gradient intensity of luminance for every rank in the gradient direction of luminance in the division region 42 and in the recognition target region 41 but also the ratio of the frequency of the rank.SELECTED DRAWING: Figure 1
【課題】処理負荷を抑制しつつ、物体を認識することができる物体認識装置を提供する。【解決手段】第1算出部51が算出した度数分布と第2算出部52が算出した階級の度数の比とを用いて、認識対象領域41に対象物体が含まれるか否かを判断している。分割領域42および認識対象領域41における輝度の勾配方向の階級ごとの輝度の勾配強度は、認識対象領域41に含まれている対象物体の特徴を表している。したがって、階級の度数の比も対象物体の有無を判断するパラメータとなる。よって、分割領域42および認識対象領域41における輝度の勾配方向の階級ごとの輝度の勾配強度だけでなく、階級の度数の比も用いることで対象物体の有無を判断することができる。【選択図】図1 |
