PROBLEM TO BE SOLVED: To provide a mobile-body-mounted imaging system capable of acquiring uniform, high-quality images throughout a predetermined interval to be imaged irrespective of the speed of a mobile body.SOLUTION: The mobile-body-mounted imaging system comprises: velocity detection means mounted in the mobile body and detecting information or a signal in response to a speed or a moving distance of the mobile body; and a line camera 4 mounted in the mobile body and performing imaging in a direction different from a progress direction of the mobile body on the basis of the information or the signal detected by the velocity detection means, and the number of times of imaging per unit time of the line camera when the mobile body moves at a first speed is set higher than the number of times of imaging per unit time of the line camera when the mobile body moves at a second speed higher than the first speed. The mobile-body-mounted imaging system comprises auxiliary signal generation means 6 generating a trigger signal 7 on the basis of a signal output from an odometer 3 and a target resolution set according to the line camera 4, and the line camera performs imaging synchronously with the trigger signal 7 generated by the auxiliary signal generation means.

    【課題】撮像する所定区間と通じて、移動体の速度に寄らず均質で高画質な画像を取得可能な移動体搭載撮像システムを提供する。【解決手段】移動体に搭載され、この移動体の速度または移動距離に応じた情報または信号を検出する速度検出手段と、移動体に搭載され、速度検出手段が検出した情報または信号に基づいて移動体の進行方向と異なる方向に向けて撮像を行うラインカメラ4を備え、ラインカメラは、移動体が第1の速度で移動するときの単位時間当たり撮像回数よりも、移動体が第1の速度よりも速い第2の速度で移動するときの単位時間当たりの撮像回数を大きくした。オドメータ3が出力する信号と、ラインカメラに応じて設定された目標解像度とに基づいてトリガ信号を生成する補助信号生成手段6を有し、ラインカメラが補助信号手段から生成するトリガ信号7に同期して撮像を行う。【選択図】図2
