To check the calibration result of camera parameters used for generation of an overhead video easily and accurately.SOLUTION: An on-vehicle device 16 includes: a video acquiring unit 21 which acquires a video around a vehicle 1 from a camera 11; a radiation control unit 25 for controlling the radiation of a luminous flux pattern by a light-emitting device 14 which irradiates the luminous flux pattern to the ground or the floor surface of a predetermined position relative to the vehicle 1; an image processing unit 24 which generates an overhead video including the luminous flux pattern, by using the video acquired by the video acquiring unit 21; a superimposed image generation unit 26 which generates a superimposed image in the position corresponding to the luminous flux pattern contained in the overhead video; and an image determination processing unit 27 which determines whether or not camera parameters for generating the overhead video is calibrated correctly, by detecting overlapped parts of lines and the image of the luminous flux pattern, in the overhead video on which the superimposed image is superimposed.SELECTED DRAWING: Figure 1

    【課題】俯瞰映像の生成に用いられるカメラパラメータのキャリブレーション結果の確認を容易に正確に行う。【解決手段】車載装置16は、カメラ11から車両1の周囲の映像を取得する映像取得部21と、車両1に対して所定の位置の地面または床面に光束パターンを照射する発光装置14による光束パターンの発光を制御する発光制御部25と、映像取得部21により取得された映像を用いて、光束パターンを含む俯瞰映像を生成する画像処理部24と、俯瞰映像に含まれる光束パターンに対応する位置に対して、重畳画像を生成する重畳画像生成部26と、重畳画像が重畳された俯瞰映像において、ラインと光束パターンの画像との重複部分を検出することにより、俯瞰映像を生成するためのカメラパラメータが正確にキャリブレーションされているか否かを判定する画像判定処理部27とを含む。【選択図】図1
