PROBLEM TO BE SOLVED: To accurately detect a foreign object present in a range that may cause a problem in non-contact electric power transmission, while inhibiting erroneous detection of foreign object caused by a sunshine change or the like, in a vehicle and an electric power transmission device for detecting a foreign object by a fish-eye camera.SOLUTION: An infrared camera 210 is provided in a central portion of an electric power transmission device 200, and configured to photograph its surroundings. A light source 220 is provided in the surroundings of the infrared camera 210, and configured to emit light in the direction of the outer periphery of the transmission device 200. The control device 240 determines that, among foreign objects photographed by the infrared camera 210 during on and off of the light source 220, a foreign object with a higher degree of luminance change synchronized with on and off of the light source 220 is located closer to the electric power transmission device 200.SELECTED DRAWING: Figure 3
【課題】魚眼カメラにより異物を検知する送電装置及び車両において、日照変化等の要因による異物の誤検知を抑制しつつ、非接触電力伝送を行なった場合に問題となる範囲に存在する異物の検知を精度良く行なう。【解決手段】赤外線カメラ210は、送電装置200の中央部分に設けられ、周囲を撮影するように構成される。光源220は、赤外線カメラ210の周囲に設けられ、送電装置200の外周方向に光を照射するように構成される。制御装置240は、光源220の点滅時に赤外線カメラ210により撮影される異物のうち、光源220の点滅に同期して輝度変化する度合いが大きい異物ほど、送電装置200に近い位置に存在すると判定する。【選択図】図3
