A method and system for video-based road departure warning for a vehicle on a road, is provided. Road departure warning involves receiving an image of a road in front of the vehicle from a video imager, and detecting one or more road markings in the image corresponding to markings on the road. Then, analyzing the characteristics of an image region beyond the detected markings to determine a rating for drivability of the road corresponding to said image region, and detecting the lateral offset of the vehicle relative to the markings on the road based on the detected road markings. A warning signal is generated as function of said lateral offset and said rating.

In apparatus and method for detecting a traffic lane mark for an automotive vehicle, a plurality of traffic lane detection windows are set in a manner for the traffic lane to be included in each traffic lane detection window from an image data photographed by a photograph device, the traffic lane mark is detected from a luminous intensity information within each traffic lane detection window of each coordinate point, a plurality of noise detection windows are set at positions which abut the respective traffic lane detection windows, an edge intensity within each noise detection window is detected; a weight value to a predetermined number of the traffic lane detection windows is modified in accordance with the edge intensity in the noise detection window; and a road contour is calculated using the traffic lane detected at the window internal traffic lane detecting and the modified weight value.

A system for realizing support of safety driving or automatic driving, in which a vehicle-mounted stereo camera is used to detect obstacles on a road surface even in the presence of a reflected image of an obstacle under a wet road condition. The system includes two cameras, an image transforming section transforming a first camera's image by image transform T that transforms any given pixel in a road surface region in the first camera's image to a corresponding pixel in a second camera's image, a lane detecting section detecting a traffic lane on a road on the basis of characteristics of the image obtained from the second camera, a similarity calculating section sequentially establishing processing regions, each having a base formed by one of image lines in a region within a lane, for carrying out inter-image arithmetic operations on the assumption that an obstacle stands from a contact line on a road surface as an image line, and obtaining respective degrees of similarity between the first cameras s image and the second camera's image and between the second camera's image and the transformed image, and an obstacle judging section detecting the object from a difference between the two kinds of degrees of similarity on the road region sequentially obtained.

A method of alerting the driver of a vehicle to a lane departure condition. The method includes operating a lane detection system to detect that the vehicle is experiencing a lane departure condition, operating a sensor to detect background vibration experienced by the vehicle, determining a characteristic making a haptic signal likely to be distinguishable from the background vibration, and operating a haptic signal generator in response to the lane departure condition to deliver to a driver the haptic signal having the characteristic.
