A method for detecting a target object, the method comprising: (a) detecting a target object, such as a beach where a wave is struck, Obtaining a foreground image from a photographed image; (B) applying a color filter to the foreground image to generate a binary image, the background object and the target object; (C) labeling the binary image with the road to identify the object and set an object block; (D) tracing a target object through template matching in the photographed image with respect to the identified object; And (e) tracking the background object and correcting the background object to the target object if the target object is within the movement range.By the same object detection method as the road, by detecting the target object such as the receiver by excluding the dynamic background object as the wave from the captured image, even if the dynamic background such as the wave is taken together, the target object such as the receiver can be accurately detected and tracked Can be.;
