SYSTEM AND METHOD FOR PERIODIC LANE MARKER IDENTIFICATION AND TRACKING
First Claim
1. A system for periodic lane marker identification comprising:
- at least one imager configured to capture a plurality of images exterior of the vehicle;
a processor in communication with the at least one imager where the processor is configured to process at least one image such that the period of the dashed lane markers in the image is calculated for tracking the vehicle within the detected dashed lane markers; and
wherein the processor communicates an output based upon the detected dashed lane markers for use by the vehicle.

Abstract
A system and method for determining the presence and period of dashed line lane markers in a roadway. The system includes an imager configured to capture a plurality of high dynamic range images exterior of the vehicle and a processor, in communication with the at least one imager such that the processor is configured to process at least one high dynamic range image. The period of the dashed lane markers in the image is calculated for detecting the presence of the dashed lane marker and for tracking the vehicle within the markers. The processor communicates an output for use by the vehicle for use in lane departure warning (LDW) and/or other driver assist features.

7. A system for periodic roadway lane marker identification comprising:
-
at least one image sensor configured to capture a plurality of high dynamic range images exterior of a vehicle; an image controller for communication data from the at least one imager; a processor in communication with the image controller such that the processor is configured to process at least one high dynamic range image such that the period of a plurality of dashed roadway lane markers is determined based on points in the image; and wherein the processor communicates an output based upon the determined period of the plurality of dashed roadway lane markers for assisting a driver. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of detecting a periodic dashed lane marker located on a roadway comprising the steps of:
-
capturing at least one high dynamic range image; detecting a periodic lane marker in the image for identifying a roadway lane; and determining if the vehicle will remain within the roadway lane such that an output is communicated for use by a vehicle. - View Dependent Claims (14, 15, 16, 17, 18)

19. A system configured to detect a raised lane marker, the system comprising:
an imager configured to capture at least one image; and a processor in communication with the imager, the processor configured to processes the at least one image, such that a horizontal slice of the image is taken, a vertical slice of a the image is taken, a plurality of points are sampled for substantially similar intensities, a raised lane marker confidence is determined, and points are group, wherein the process is configured to detect a raised lane marker in the image.

20. A collision avoidance system for a vehicle comprising:
-
an imager configured to capture a plurality of high dynamic range images exterior of the vehicle; and at least one processor in communication with the imager, the processor configured to process the one or more captured high dynamic range images, such that motion of objects in the image are detected, and determining if the vehicle will collide with the detected object, such that the processor communicates an output to avoid the collision.
