According to another aspect of the present invention, a driving trajectory guide and collision warning method includes: displaying a front wheel and a rear wheel trajectory of the vehicle on a front image or a rear image of a photographed vehicle; And when an obstacle is detected at the front or rear of the vehicle and the detected obstacle is located on at least one driving trajectory of the front wheel and the rear wheel, transmitting a possibility of contact or collision with the obstacle as a warning message. Include.
According to the present invention, by informing the trajectories of all the wheels of the vehicle when moving forward and backward, the driver can intuitively know the direction of travel of the vehicle, and thus it is possible to easily determine whether there is contact with an obstacle.
In particular, it is possible to prevent damage to the vehicle due to the collision by notifying the collision with the obstacle in advance by calculating the distance between the measured obstacle and the front wheel and the rear wheel.
