PROBLEM TO BE SOLVED: To correctly recognize a target object from an image photographed with a camera.SOLUTION: An image processing apparatus 1 includes a contrast correcting unit 12, a color analyzing unit 13, an object detecting unit 14, and an object association analyzing unit 15. The contrast correcting unit 12 creates a contrast-corrected image in which contrast of an input image photographed by an in-vehicle camera that is mounted to a vehicle is corrected. The color analyzing unit 13 creates a color-corrected image in which a color of the input image is corrected. The object detecting unit 14 detects a sign included in the input image on the basis of the contrast-corrected image, and detects a marking included in the input image on the basis of the color-corrected image. The object association analyzing unit 15 recognizes the sign and the marking that are target objects on the basis of a time series association between the sign and the marking detected by the object detecting unit 14.SELECTED DRAWING: Figure 1
【課題】カメラで撮影された画像から対象物を正しく認識する。【解決手段】画像処理装置1は、明暗補正部12と、色解析部13と、物体検出部14と、物体関連解析部15と、を備える。明暗補正部11は、車両に搭載された車載カメラによって撮影された入力画像の明暗を補正した明暗補正画像を作成する。色解析部13は、入力画像の色を補正した色補正画像を作成する。物体検出部14は、明暗補正画像に基づいて入力画像に含まれる標識を検出し、色補正画像に基づいて入力画像に含まれる標示を検出する。物体関連解析部15は、物体検出部14により検出された標識と標示の時系列での関連性に基づいて、対象物である標識および標示を認識する。【選択図】図1
