PROBLEM TO BE SOLVED: To provide a camera parameter adjustment device capable of preventing a contour of one subject from being displayed while being displaced at a joint between partial bird's-eye-view images even if the subject is displayed over a plurality of partial bird's-eye-view images in an integrated bird's-eye-view image.SOLUTION: If the same object is imaged by a front camera 2 as a reference camera and a rear camera 3 as an adjustment target camera, a displacement degree calculation part calculates a degree of displacement between a relative position of that object (defined as a common imaging object) that is determined from an image captured by the front camera 2 and a relative position of the common imaging object that is determined from an image captured by the rear camera 3. A parameter calculation part calculates such a camera parameter that the degree of displacement becomes 0 (namely, a matched parameter) as a camera parameter of the rear camera 3. A bird's-eye view conversion processing part then uses the calculated matched parameter to generate a rear bird's-eye-view image from the image that is captured by the rear camera 3.SELECTED DRAWING: Figure 1

    【課題】統合俯瞰画像において1つの被写体が複数の部分俯瞰画像にまたがって表示される場合であっても、その被写体の輪郭が部分俯瞰画像同士の繋ぎ目においてずれて表示されることを抑制可能なカメラパラメータ調整装置を提供する。【解決手段】、基準カメラとしての前方カメラ2と、調整対象カメラとしての後方カメラ3とが同一の物体を撮影した場合には、ずれ度合い算出部が、前方カメラ2が撮影した画像から定まるその物体(共通撮影物とする)の相対位置と、後方カメラ3が撮影した画像から定まるその共通撮影物の相対位置とのずれ度合いを算出する。また、パラメータ算出部は、後方カメラ3のカメラパラメータとして、そのずれ度合いが0となるカメラパラメータ(つまり整合化パラメータ)を算出する。そして、俯瞰変換処理部は、算出された整合化パラメータを用いて、後方カメラ3が撮影した画像から後方俯瞰画像を生成する。【選択図】図1
