Clear path detection using segmentation-based method
First Claim
Patent Images
1. Method for detecting a clear path of travel for a vehicle by segmenting an image generated by a camera device located upon the vehicle, the method comprising:
- monitoring the image;
analyzing the image with a plurality of analysis methods, each analysis methodsegmenting a respective region of the image that cannot represent the clear path of traveldefining the clear path of travel based uponsubtracting each respective region of the image that cannot represent the clear path of travel from the image,identifying one or more remaining regions after each respective region of the image that cannot represent the clear path of travel has been subtracted, andidentifying, through geometric analysis, the clear path of travel corresponding only to ones of the remaining regions that comprise a parallelogram-based shape indicative of either one of a current lane of travel and a neighboring lane of travel; and
utilizing the clear path of travel to navigate the vehicle.

Abstract
A method for detecting a clear path of travel for a vehicle by segmenting an image generated by a camera device located upon the vehicle includes monitoring the image, analyzing the image with a plurality of analysis methods to segment a region of the image that cannot represent the clear path of travel from a region of the image that can represent the clear path of travel, defining the clear path of travel based upon the analyzing, and utilizing the clear path of travel to navigate the vehicle.

1. Method for detecting a clear path of travel for a vehicle by segmenting an image generated by a camera device located upon the vehicle, the method comprising:
-
monitoring the image; analyzing the image with a plurality of analysis methods, each analysis method segmenting a respective region of the image that cannot represent the clear path of travel defining the clear path of travel based upon subtracting each respective region of the image that cannot represent the clear path of travel from the image, identifying one or more remaining regions after each respective region of the image that cannot represent the clear path of travel has been subtracted, and identifying, through geometric analysis, the clear path of travel corresponding only to ones of the remaining regions that comprise a parallelogram-based shape indicative of either one of a current lane of travel and a neighboring lane of travel; and utilizing the clear path of travel to navigate the vehicle. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. Method for detecting a clear path of travel for a vehicle by segmenting an image generated by a camera device located upon the vehicle, the method comprising:
-
monitoring the image; pre-processing the image, comprising analyzing the image with a plurality of analysis methods, each analysis method segmenting a respective region of the image that cannot represent the clear path of travel; analyzing the image through clear path detection analysis based upon the pre-processing to determine a clear path of travel within the image, comprising; subtracting each respective region of the image that cannot represent the clear path of travel from the image, identifying one or more remaining regions after each respective region of the image that cannot represent the clear path of travel has been subtracted, and identifying, through geometric analysis, the clear path of travel corresponding only to ones of the remaining regions that comprise a parallelogram-based shape indicative of either one of a current lane of travel and a neighboring lane of travel; and utilizing the clear path of travel to navigate the vehicle. - View Dependent Claims (12, 13, 14)
