PROBLEM TO BE SOLVED: To prevent erroneous detection of a foreign substance in a foreign substance detection device for detecting the foreign substance that is intruded between a power transmitting part and a power receiving part for performing power transmission in a non-contact manner therebetween.SOLUTION: A foreign substance detection device 130 includes: a camera 131 for imaging a detected object 0 through a fisheye lens; and a distance sensor 132 for measuring a distance between the camera 131 and a detected object 9. A detection part 133 defines a three-dimensional virtual region S1 enclosed by a virtual surface that virtually connecting an outer periphery of a power transmitting part 120 and an outer periphery of a power receiving part 210, the power transmitting part 120 and the power receiving part 210. In the case where the detected object 9 is imaged by the camera 131, the detection part 133 uses the distance sensor 132 to discriminate whether the detected object 9 is inside or outside of the virtual region 131 and in the case where it is discriminated that the detected object 9 is inside of the virtual region S1, the detected object 9 is detected as a foreign substance. In the case where it is discriminated that the detected object 9 is outside of the virtual region S1, on the other hand, the detected object 9 is not detected as a foreign substance.SELECTED DRAWING: Figure 4

    【課題】非接触で電力伝送を行なう送電部と受電部との間に侵入した異物を検知するための異物検知装置において、異物の誤検知を防止する。【解決手段】異物検知装置130は、被検知物0を魚眼レンズを通して撮影するカメラ131と、カメラ131と被検知物9との間の距離を測定する距離センサ132とを含む。検知部133は、送電部120の外周と受電部210の外周とを仮想的に結ぶ仮想面と、送電部120と、受電部210とにより囲まれた3次元の仮想領域S1を規定する。検知部133は、カメラ131により被検知物9が撮影された場合に、被検知物9が仮想領域131の内部にあるか外部にあるかを距離センサ132を用いて判定し、被検知物9が仮想領域S1の内部にあると判定したときには、被検知物9を異物として検知する一方で、被検知物9が仮想領域S1の外部にあると判定したときには、被検知物9を異物として検知しない。【選択図】図4
