Problems solved by technology

[0005] At present, the method of vehicle collision avoidance warning is mainly based on the relative speed and vehicle distance to judge whether to make a warning, but the technical realization of this method is more difficult and the error will be relatively large, especially based on image recognition technology. When it is implemented, the calculation of the vehicle distance in the first method will have certain errors, and the calculation of the relative speed is relatively difficult.

Abstract

The invention discloses a vehicle anti-collision judgment method based on stop lamp identification. The method is executed when the driving speed of a vehicle reaches a certain value. The method mainly comprises the steps that the preceding driving vehicle is detected according to input image data, stop lamps of the detected preceding vehicle are identified, and therefore the braking situation of the preceding vehicle is prompted in the high-speed driving process. By means of the vehicle anti-collision judgment method, the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for judging vehicle collision avoidance based on brake light recognition. Background technique [0002] Brake lights are generally installed at the rear of the vehicle, and the main color is red, so that vehicles driving behind can easily find the brakes of the vehicle in front, so as to prevent rear-end collision accidents. The simple model is that the power goes through the insurance, and then goes to the brake switch. When the brake pedal is stepped on to brake, the switch is connected, and the power is sent to two brake lights and a high-mounted brake light, which are connected to the car body through the negative line to form a circuit. [0003] The brake light is composed of two parts: one is the brake light installed at both ends of the rear of the car, which is a kind of car tail light; the other is the high-position brake light, which is installed on the upper ...
