PROBLEM TO BE SOLVED: To provide an image processor and an image processing program capable of flexibly detecting an object even through the shape of the object in a processing mage changes.SOLUTION: An image processor 10 according to an embodiment of this invention includes a dictionary generation part 21, a processing image generation part 22 and a detection part 23. The dictionary generation part 21 arranges a detection object at a plurality of positions of a prescribed range within an imaging range of a camera 11 such that a prescribed visual axis of the camera 11 mounted in a vehicle to image the periphery of the vehicle at a wide viewing angle is parallel with a normal direction of a detection object surface of the detection object to generate one dictionary in advance by using images obtained by previously imaging the detection objects at each of the plurality of positions by the camera 11. The processing image generation part 22 generates a processing image with a prescribed visual axis as a normal direction from an image picked up by the camera 11 after generating the dictionary. The detection part 23 detects the detection object included in the processing image by acquiring a prescribed feature mount by using the dictionary.

    【課題】処理画像内の対象物の形状が変化しても柔軟に対象物を検出することができる画像処理装置および画像処理プログラムを提供する。【解決手段】本発明の一実施形態に係る画像処理装置10は、辞書生成部21、処理画像生成部22および検出部23を備える。辞書生成部21は、車両に設けられ車両の周囲を広画角に撮像するカメラ11の所定の視線軸と、検出対象物の検出対象面の法線方向と、が平行となるように検出対象物をカメラ11の撮像範囲内の所定範囲の複数の位置に配置して、カメラ11により複数の位置のそれぞれで事前に検出対象物を撮像した画像を用いてあらかじめ1つの辞書を生成しておく。処理画像生成部22は、辞書の生成後にカメラ11により撮像された画像から所定の視線軸を法線方向とする処理画像を生成する。検出部23は、処理画像に含まれる検出対象物を、辞書を用いて所定の特徴量を求めることにより検出する。【選択図】 図1
