WARNING METHOD AND DEVICE FOR DEVIATION OF A MOVING VEHICLE
First Claim
Patent Images
1. A warning method for deviation of a moving vehicle, comprising the steps of:
- continuously capturing images of a road behind the moving vehicle;
analyzing a static background of the road from the captured continuous images, the static background comprising lane-dividing lines on the road;
determining whether the vehicle is deviating by checking a relative position of the moving vehicle with respect to the lane-dividing lines;
outputting a warning signal when the moving vehicle has deviated from its original lane.

Abstract
A warning method for deviation of a moving vehicle and the device of the same uses a video camera to continuously capture road images behind the vehicle and generates a video signal. A graphics processor analyzes a static background of the road based on the video signal, analyzes whether the vehicle deviates from its original path, and decides whether any moving object approaches the vehicle. In any abnormal circumstance, the graphics processor outputs a signal to a microprocessor. The microprocessor then drives an alarm to set off a warning signal to notify the driver.

16. A warning device for deviation of a moving vehicle comprising:
-
at least one video camera mounted at an appropriate position on the moving vehicle to continuously capture images of a road behind the moving vehicle and generate a video signal; at least one graphics processor connected to the video camera to receive the video signals from the video camera, the graphic processor analyzing a static background on the road, analyzing whether the moving vehicle is deviating from its original path, and determining whether any surrounding dynamic object is approaching; a microprocessor connected to the graphics processor and using the determination result of the graphics processor to determine whether to set off a warning to the driver; and an alarm connected to the microprocessor and controlled by the microprocessor to set off the warning. - View Dependent Claims (17, 18, 19, 20)
