Wireless electric energy transmission metal foreign matter detection system capable of eliminating detection blind area

The invention discloses a wireless electric energy transmission metal object detection system for eliminating a detection blind area, which comprises a transmitting coil, a receiving coil, a transverse detection coil group and a longitudinal detection coil group, the transverse detection coil group and the longitudinal detection coil group form an MOD system, each of the transverse detection coil group and the longitudinal detection coil group is composed of an odd number of rectangular coils, wherein the transverse detection coil group is arranged above the transmitting coil, and transverse foreign matter detection is realized by comparing whether a positive Y region detection voltage difference and a negative Y region detection voltage difference are equal or not; the longitudinal detection coil group is arranged above the transverse detection coil group, and longitudinal foreign matter detection is realized by comparing whether the positive X region detection voltage difference and the negative X region de
