Automobile microwave radar anti-collision early-warning method and system based on video fusion

Abstract

The invention discloses an automobile microwave radar anti-collision early-warning method based on video fusion. A radar sensor detects a target in front, a camera acquires video images in front, and the detected target data and the acquired video data are sent to a video fusion and display terminal; and the video fusion and display terminal receives the target data, collision alarming discrimination is performed on the target, video fusing and warning are carried out according to the collision alarming discrimination result, after video fusion, the target image of the video displayed on the display screen is finally marked with the target through different signs in real time, and meanwhile, the target is displayed on an analog lane displayed on the display screen through different signs in real time. The invention also discloses a system for implementing the method. As video and radar data are fused, a user can learn about the road conditions in front; a sound alarm can be given according to the 'dangerous target collision judgment criterion' to prompt a driver that a danger exists in front, so that the misjudgment rate is reduced; and the automobile microwave radar anti-collision early-warning system can be conveniently mounted on an uneven automobile central control platform.

Description

technical field [0001] The invention relates to an automobile microwave radar anti-collision early warning method and system based on video fusion. Background technique [0002] Along with improving day by day of people's living standard, while automobile has brought many conveniences to people's life, also makes traffic accident constantly increase, and car accident has brought shadow to people. In order to improve the safety of automobiles and reduce the harm caused by traffic accidents, anti-collision warning systems are generally installed on automobiles. However, the characteristics and performance of existing various anti-collision warning systems for automobiles are analyzed, and there are following defects: 1. Due to the simple application of a single radar module, the fusion of video and radar has not been achieved, and the driver has not been prompted with an intuitive display interface; High alarm rate; 3. The domestic collision avoidance system does not make rec...
