Embodiment Construction

[0046] The present invention relates to a "vehicle deviation detection method and device". The vehicle deviation detection method mainly includes an image recognition processing program and a deviation estimation processing program. Please refer to figure 1 shown, where:

[0047] The image recognition processing program uses the quadratic curve fitting equation to construct the lane line model to facilitate various types of discrimination. If the actual lane line is obscured by other vehicles, the existing line fitting method can still be used to obtain the lane line. Because The straight line fitting method belongs to the prior art and will not be described in detail; the image recognition processing program includes the following steps:

[0048] Image capture step: use the camera unit to install on the vehicle, and capture the image data of the road ahead of the vehicle;

[0049] Lane line recognition step: divide the image frame data captured by the camera unit into upper ...

Abstract

The invention relates to a checking method and a device of automobile deviation, wherein the method is mainly an image identification and processing procedure, wherein the image identification and processing procedure comprises the following steps: an image acquisition step which comprises utilizing an image pick-up device to extract image picture data, and a lane line identification step which comprises analyzing image picture data, distinguishing a lane line position, utilizing a quadratic curve to fit an equation, connecting a segmental lane line, and making a lane line predicating model, wherein the lane line predicating module which is got through utilizing the above steps is used to check automobile deviation, and is supplied for warning. The checking method of automobile deviation mainly comprises an image pick-up device which is used to extract road image information, a calculating platform which is used to analyze the road image information extracted by the image pick-up unit, and judges the corresponding relationship of a current automobile and a road, and a signal outlet unit which utilizes light, visual variation or sound to reach the behavior of warning. The invention can give off warning to prompt a driver to pay attention and reach the behavior of warning when an automobile does not normally run.

Description

technical field [0001] The invention relates to a detection method and device for vehicle deviation. Background technique [0002] With the popularization and widespread use of vehicles in human society, the gap between different regions has been shortened, and it has gradually become a globalized social form. However, in recent years, traffic accidents have caused an endless stream of casualties. Therefore, advanced countries and major car manufacturers are actively seeking how to apply technology. on the vehicle to improve the safety of the vehicle and reduce the incidence of traffic accidents; [0003] In the occurrence of traffic accidents, human factors often account for the majority, and fatigue and distraction are often the main causes of accidents. Although relevant institutions at home and abroad are working on drowsiness detection, brain waves and other related research to remind drivers, the effect is not as good as Satisfactory, coupled with system response time...
