摘要： A method for detecting a clear path of travel for a vehicle utilizing analysis of a plurality of images generated by a camera device located upon the vehicle includes monitoring the images wherein each image comprises a plurality of pixels, utilizing a texture-less processing scheme to analyze the images including filtering the image to separate portions of the image indicating a clear surface upon which a potential road surface can be estimated from other portions of the image that do not indicate a potential road surface. The clear path is determined based upon the clear surface and the clear path is utilized to operate the vehicle.

摘要： A method for detecting a clear path of travel for a vehicle using an image generated by a camera includes monitoring the image, and utilizing a first patch-based analysis of the image including dividing the image into a plurality of patches, and analyzing each patch to determine a first clear path confidence likelihood for each of the patches of the first patch-based analysis. Each of the patches with the first clear path confidence likelihood greater than a first threshold confidence likelihood is defined as a clear path patch. A second analysis is utilized upon a portion of the patches with the first clear path confidence not greater than the first threshold confidence likelihood to determine a second clear path confidence likelihood for each of the patches of the second analysis. Each of the patches of the second analysis with the second clear path confidence likelihood greater than a second threshold confidence likelihood is defined as a clear path patch. The clear path of travel for the vehicle is identified based upon the clear path patches.

摘要： An active vision system includes an image capture device for capturing images in a region exterior of a vehicle and a headlamp control unit for controlling a vehicle headlamp beam for illuminating an environment exterior of a vehicle. The headlamp control unit is configured to selectively illuminate between making a path of travel of a road visible to a driver of the vehicle and making the region exterior of the vehicle visible for capturing images by the image capture device. The headlamp control unit utilizes a duty cycle for controlling a first cycle time that the headlamp beam illuminates the path of travel for making the road visible to the driver and for controlling a second cycle time that the headlamp beam makes the captured region visible for capturing images by the image capture device.
