DUAL-VISION DRIVING SAFETY WARNING DEVICE AND METHOD THEREOF
First Claim
1. A dual-vision driving safety warning device comprisingan image capture unit including at least two image capture devices installed in a user'"'"'s vehicle and capturing images of a front traffic environment, wherein said images 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, and used to process said images and calculate a distance between said user'"'"'s vehicle and a 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 the image processing unit and said vehicle status sensing unit, and controlled by said control signal to send out a warning signal.

Abstract
The present invention discloses a dual-vision driving safety warning device and a method thereof. The device of the present invention comprises an image capture unit, an image processing unit, a vehicle status sensing unit, a warning judgment logic, and at least one warning unit. The image capture unit includes at least two image capture devices installed in a user'"'"'s vehicle and capturing the images of the front traffic environment. The image processing unit processes the images and uses the vehicle status signals detected by the vehicle status sensing unit to calculate the distance between the user'"'"'s vehicle and a front vehicle in the image. The warning judgment logic sends out a control signal when the user'"'"'s vehicle deviates from a driving lane or approaches a front vehicle too much. The warning unit receives the control signal and sends out a warning signal, such as a sound or a flash, to remind the driver.
