1. A detection system for a vehicle, the system comprising:
- at least one camera configured to acquire a plurality of images of an area forward of the vehicle, the area including a curb separating a road surface from an off-road surface;
a data interface; and
at least one processing device programmed to;
receive the plurality of images output from the at least one camera via the data interface;
determine a plurality of curb edge line candidates from and within the plurality of images of the area forward of the vehicle; and
identify at least one curb edge line candidate as an edge line of the curb.

Abstract
A detection system for a vehicle is provided. The detection system may include at least one image capture device configured to acquire a plurality of images of an area forward of the vehicle, the area including a curb separating a road surface from an off-road surface and a data interface. The detection system may also include at least one processing device programmed to receive the plurality of images via the data interface, and determine a plurality of curb edge line candidates in the plurality of images. The at least one processing device may be further programmed to identify at least one edge line candidate as an edge line of the curb.

13. A vehicle, comprising:
-
a body; at least one camera configured to acquire a plurality of images of an area forward of the vehicle, the area including a curb separating a road surface from an off-road surface; a data interface; and at least one processing device programmed to; receive the plurality of images output from the at least one camera via the data interface; determine a plurality of curb edge line candidates from and within the plurality of images of the area forward of the vehicle; identify at least one curb edge line candidate as an edge line of the curb; and identify regions in the plurality of images that correspond to the road surface and the off-road surface based on the identified edge line of the curb. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for curb detection, the method comprising:
-
acquiring, via at least one camera, a plurality of images of an area forward of a vehicle, the area including a curb separating a road surface from an off-road surface; determining a plurality of curb edge line candidates from and within the plurality of images of the area forward of the vehicle; determining a height of a step function associated with each curb edge line candidate; and identifying at least one curb edge line candidate as an edge line of the curb based on the determined heights. - View Dependent Claims (20)
