一种用于检测作为无线能量传输系统的一部分的源谐振器附近的异物的系统和方法。 无线能量传输系统可以是用于对电动车辆的电池进行无线充电的系统。 来自可见光照相机和多区域温度传感器的数据被组合或融合以确定诸如金属物体或动物之类的外来物体是否在源极谐振器附近或接近源极谐振器。 该系统基于是否检测到异物来减少或抑制由源极谐振器发射的能量来控制提供给源谐振器的电流。 可见光相机可以是单色或彩色相机，并且温度传感器可以是红外相机或热电堆阵列。

System and method for detecting foreign matter in a part close to the source resonator of the wireless energy transmission system. A wireless energy transfer system may be used to charge the battery of the electric vehicle by radio. A visible light camera and data from a multi-zone temperature sensor is, foreign material, such as metal objects or animals, are combined or fused to determine whether the source close to the resonator or in the vicinity of the source cavity. The system, based on whether or not the foreign matter is detected, by controlling the current provided to the source cavity, decreases or suppresses the energy emitted by the source resonator. A visible light camera may be a monochrome or a color camera, a temperature sensor may be an infrared camera or a thermopile array.
