Abstract:
The present invention relates to a system and method for photographing a moving subject by means of a fixed camera, and acquiring a projection image of the actual movement trajectory of the subject on the basis of the photographed image. One embodiment of the present invention provides a method for acquiring a projection image of the actual movement trajectory of a subject, the method comprising: a step for photographing a moving subject by means of a fixed camera; and a step for converting the coordinates of the photographed image of the subject on the camera image frame to coordinates of the image on an actual background portion, the conversion being implemented on the basis of information on mapping between coordinates on an actual background portion having a specific pattern, acquired by pre-photographing, with a fixed camera, the specific pattern of the actual background portion, and the coordinates on the camera image frame of the photographed image thereof.
