Embodiment Construction

[0040]The present invention mainly uses the integrated monocular camera on the mobile phone to collect images of the information of the road ahead, vehicles and pedestrians, and performs real-time analysis and calculation on the information collected by the camera through the intelligent processing units such as image analysis and pattern recognition algorithms of the mobile phone camera. , so as to estimate the position of the lane, the distance to the vehicle in front, whether there are pedestrians in front, etc., and display the results on the screen of the mobile phone. In case of danger, the driver will be reminded in time to prevent the driver from being fatigued or distracted. A traffic accident occurs.

[0041] The present invention will be further described below in conjunction with the embodiment that accompanying drawing provides:

[0042] Such as figure 1 As mentioned above, the present invention mainly includes several stages of image acquisition, image preproces...

Abstract

The invention discloses an active safety early-warning method for an automobile. The method mainly comprises the following steps of performing image acquisition on information about a front road, a front vehicle and a front pedestrian by using a monocular camera integrated on a mobile phone, performing real-time analytical calculation on the information acquired by the camera so as to estimate results such as the position of a lane where the automobile is located, a distance between the automobile and the front vehicle and whether the pedestrian is in front of the automobile or not by using intelligent processing units such as image analysis and a mode recognition algorithm of the camera of the mobile phone, and displaying the results on a screen of the mobile phone to timely prompt a driver under a dangerous condition and prevent accidents under the condition of fatigue or distraction of the driver. According to the method, the occurrence rate of the accidents can be effectively reduced.

Description

technical field [0001] The invention relates to an early warning method for active safety of automobiles, in particular to an early warning method for active safety of automobiles based on a mobile phone. Background technique [0002] By the end of 2011, the number of cars in the country reached 106 million, and the number of traffic accidents reported nationwide in the first half of 2011 reached 184,000. According to research, 1 / 3 of these traffic accidents were caused by changing lanes or driving off the road, 2 / 3 is caused by the driver's inattention; with the increase of the total number of automobiles, the total number of traffic accidents and casualties of automobiles is also increasing, and the safety of automobiles has increasingly become the focus of society Focus, which makes automotive active safety technology more and more favored by drivers and major automobile manufacturers; therefore, various automobile manufacturers have begun to pre-install automotive activ...
