Patent ID: 8723660

Claim:
A dual-vision driving safety warning device comprising an image capture unit including at least two image capture devices installed in a user's vehicle, wherein said image capture devices respectively have different elevation angles and respectively capture a near-field image and a far-field image of a front traffic environment, and wherein said near-field image and said far-field image at least contain images of complete lane marks; a vehicle status sensing unit sensing at least one status signal of said user's vehicle, including a signal of speed, braking, or a direction light; an image processing unit including a lane mark detection algorithm, a detection angle algorithm, a front vehicle detection algorithm, a distance estimation algorithm and a distance calibration algorithm, using them to process said near-field image and said far-field image and using said detection angle algorithm and said elevation angles with respect to a front vehicle in said near-field image and said far-field image to calculate a distance between said user's vehicle and said front vehicle; a warning judgement logic integrating said vehicle status signal and calculation results of said image processing unit to perform an adaptive cruise control function and sending out a control signal when said user's vehicle deviates from a driving lane or approaches said front vehicle too much; and at least a warning unit connected said image processing unit and said vehicle status sensing unit, and controlled by said control signal to send out a warning signal.
