Mobile-phone-based active safety early-warning method for automobile

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.
