1. A vehicle path restoration method through sequential image analysis, comprising:
acquiring sequential images from a front camera of an image capturing unit installed in a subject vehicle;
generating a path of the subject vehicle and a front vehicle by receiving the sequential image and performing image analysis in an image analysis unit; and
expressing the image analysis of the image analysis unit in the form of a top view on a display unit,
wherein the performing image analysis in the image analysis unit comprises:
determining a lane of the current time;
generating a multi-lane recognizable in the front camera image and a multi-path for each index calculated using geometric characteristics of the lane recognized at the current time and the speed of the subject vehicle,
generating a path set of each index in the multi-path, wherein the generating the path set of each index in the multi-path comprises:
receiving input information that is input data for creating the path set;
determining whether the path is a curved lane or a straight lane;
generating a curved path when the path is determined as the curved lane;
generating a straight path when the path is determined as the straight lane; and
creating a path set of the corresponding index by integrating the curved path and the straight path;
generating path data of the subject vehicle based on the path set; and
generating path data of the front vehicle based on the path set.
