Abstract

The invention discloses a self-adaptive vision lane departure pre-warning device and relates to a vehicle safety system. The self-adaptive vision lane departure pre-warning device is provided with a vehicle-mounted power supply, a voltage-reducing and voltage-stabilizing circuit, an alerter, an FPGA (Field Programmable Gate Array) core board, a digital camera and a steering angle inductor, wherein the input end of the voltage-reducing and voltage-stabilizing circuit is connected with the output end of the vehicle-mounted power supply, the output end of the voltage-reducing and voltage-stabilizing circuit is respectively connected with the input end of a power module of the FPGA core board and the input end of the digital camera, an output interface of the FPGA core board is connected with the input end of the alerter, the output end of the digital camera is connected with an input interface of the FPGA core board, the output end of the digital camera is connected with the input interface of the FPGA core board, and the output end of the steering angle inductor is connected with the input interface of the FPGA core board. The lane line identification capability of the self-adaptive vision lane departure pre-warning device under the conditions of complicated illumination and complicated road surfaces is improved. The departure pre-warning capability of the vision lane departure pre-warning device is improved. The image processing speed and the pre-warning response speed of the traditional vision lane departure pre-warning device are improved.

Description

technical field [0001] The invention relates to a vehicle safety system, in particular to an adaptive visual lane departure warning device. technical background [0002] With the rapid development of information and automatic control technology, automobile driving assistance technology is gradually accepted by automobile manufacturers and users. Lane departure warning devices can prevent or reduce traffic accidents caused by driver fatigue, and have gradually become the standard configuration of high-end car brands. The vision-based lane line tracking warning device is the mainstream technical route of lane departure warning products. [0003] Visual lane tracking and departure warning devices generally include three main modules: (1) video acquisition module; (2) image analysis module; (3) user warning module. Among them, the image analysis module is responsible for the task of identifying lane lines, which is the core technology of the visual lane departure warning devic...
