1. A method of determining an accident image using recognition results of an obstacle on a road, by a blackbox or impact event generation apparatus installed in a vehicle, whether an image before or after impact detection timing is an actual accident image or a fake accident image, by using results of recognition of an obstacle on a road, the method comprising steps of:
(a) obtaining, by a camera module of the vehicle, a photographed image of a road ahead of the vehicle, and detecting, by a processor provided in a blackbox or an impact event generation apparatus, an obstacle, which is located on the road ahead of the vehicle and whose impact is neglectable, from the photographed image;
(b) determining, by the processor, a pass start time (T1) when the vehicle starts to pass through the obstacle and a pass end time (T2) when the vehicle completely goes over the obstacle;
(c-1) detecting, by the processor, an occurrence of the impact event from an impact detection signal obtained by an impact detection sensor or a car area network (CAN) included the blackbox;
(c-2) determining, by the processor, whether an impact event occurrence timing (Tc) is located between the pass start time (T1) and the pass end time (T2) when the impact event occurs;
(c-3) determining, by the processor, the impact event to have a low accident possibility when the impact event occurrence timing (Tc) is located between the pass start time (T1) and the pass end time (T2); and
(c-4) determining, by the processor, the impact event to have a high accident possibility when the impact event occurrence timing (Tc) is located before the pass start time (T1) or after the pass end time (T2).
