PROBLEM TO BE SOLVED: To provide a vehicle image processor capable of reducing dynamic distortion of a camera.SOLUTION: An image frame when vehicle information shows that distortion does not occur in an image of an on-vehicle camera is regarded as a frame without distortion, and planar objects in each image frame are extracted from feature points to associate each planar object with the feature point. About each planar object in which the number of the associated feature points exceeds a predetermined threshold, a distortion amount to a planar object of the frame without distortion is calculated, and each image frame undergoes image correction according to the distortion amount.SELECTED DRAWING: Figure 1

    【課題】カメラの動的な歪みを軽減できる車両画像処理装置を提供する。【解決手段】車両情報が前記車載カメラの画像には歪みが生じないことを示しているときの画像フレームを歪み無しフレームと見做し、前記特徴点から各画像フレーム中の平面物体を抽出して各平面物体とその特徴点との対応付けを行う。これらの対応付けられた特徴点の数が予め決められた閾値を越える各平面物体について、前記歪み無しフレームの平面物体に対する歪み量を求め、各画像フレームを前記歪み量に応じて画像補正を行う。【選択図】図1
