Abstract

Disclosed is a parking assist system including a camera unit for photographing front or rear view of a vehicle, and a display unit for displaying a front or rear view image of the vehicle photographed by the camera unit, the system characterized by: a processor unit generating a first and second parking guide line, one being perpendicular to the other, at an area which is apart from the vehicle by a predetermined distance, and generating an estimated travel trajectory line based on steering angle information obtained from a steering angle sensor of the vehicle; and an overlay unit for overlaying the photographed front or rear view image of the vehicle on the first and second parking guide lines and the estimated travel trajectory line.

Claims

1. A parking assist system including a camera unit for photographing front or rear view of a vehicle, and a display unit for displaying the front or rear view image of the vehicle photographed by the camera unit, the system characterized by:

a processor unit generating a first and second parking guide line, one being perpendicular to the other, at an area which is apart from the vehicle by a predetermined distance, and generating an estimated travel trajectory line based on steering angle information obtained from a steering angle sensor of the vehicle; and

an overlay unit for overlaying the first and second parking guide lines and the estimated travel trajectory line on the photographed front or rear view image of the vehicle.

2. The parking assist system of claim 1, characterized in that the processor unit detects a parking target area from the photographed front or rear view image of the vehicle to generate an imaginary parking line.

3. The parking assist system of claim 1, characterized in that the processor unit detects at least one parking target area from the photographed front or rear view image of the vehicle to extract two outer corners of the at least one parking target area as two reference points and to generate an imaginary parking line connecting the two reference points.

4. The parking assist system of claim 2, characterized in that the processor unit overlays the estimated travel trajectory line on the photographed front or rear view image of the vehicle, if relationship between the imaginary parking line and the first and second parking guide lines meets a predetermined condition.

5. The parking assist system of claim 1, characterized in that the processor unit generates a first parking guide line which is apart from a center of a front axle or a rear axle by a predetermined distance and is perpendicular to the front axle or the rear axle, and a second parking guide line which is apart from the center of the front axle or the rear axle by a predetermined distance and is parallel with the front axle or the rear axle.

6. The parking assist system of claim 2, characterized in that the processor unit determines whether an angle between the imaginary parking line and any one parking guide line of the first and second parking guide lines falls into a predetermined range.

7. The parking assist system of claim 6, characterized in that the overlay unit overlays the estimated travel trajectory line on the photographed front or rear view image of the vehicle based on the steering angle information of the vehicle, if the angle between the imaginary parking line and any one parking guide line of the first and second parking guide lines falls into the predetermined range.

8. The parking assist system of claim 3, characterized in that the processor unit determines whether a coordinate of a reference point nearest to the vehicle in the reference points corresponds to a coordinate of an intersection point between the first and second parking guide lines.

9. The parking assist system of claim 8, characterized in that the overlay unit overlays the estimated travel trajectory line on the photographed front or rear view image of the vehicle based on the steering angle information of the vehicle, if the coordinate of the reference point nearest to the vehicle in the reference points corresponds to the coordinate of the intersection point between the first and second parking guide lines.

10. The parking assist system of claim 1, characterized in that the overlay unit sequentially updates the estimated travel trajectory line as the vehicle advances to the parking target area.
