The present invention provides a wireless charging safety management system which comprises a transmitter for wirelessly transmitting power to electric vehicle vehicles and a CCTV camera system for detecting abnormal situations by constantly filming a wireless charging parking area. The system is characterized by performing the steps of: obtaining an average pixel value by multiplying the pixel value at each location of a video frame acquired through a CCTV camera by the frame weight over time and adding the resulting value, and obtaining an average image with the average pixel value at all locations of the video and register it as a background image; and obtaining a global mask image where the pixel value is 1 if the pixel value is above a given threshold value and 0 if the pixel value is below a threshold value, and, if the pixels with a value of 1 in the global mask image are gathered within a certain distance to form a region, registering the region as a foreground region.
