Abstract

The invention discloses an automobile safety warning device and method based on binocular stereo vision and belongs to the safety equipment field. Binocular camera units are used for obtaining images of front vehicles and rear vehicles, a minimum distance is obtained according to calibration results and matching results of the images, comparisons between the minimum distance and a safety distance are performed, and a function of the warning of a buzzer inside the automobile and a function of LED (light-emitting diode) display warning on the tail portion of the automobile are achieved. According to the automobile safety warning device and method based on the binocular stereo vision, the binocular stereo vision distance-measuring devices have a great price advantage; the stereo vision distance-measuring method can obtain image information of an automobile and can obtain more information; besides, due to the fact that cameras, an automatic aperture technology and an automatic white balance technology are combined in usage, the automobile safety warning device and method based on the binocular stereo vision can be applied to poor visible conditions, such as at night and in tunnels. Therefore, the automobile safety warning device and method based on the binocular stereo vision has a broad prospect in field of automobile safety distance measurement.

Description

technical field [0001] The invention belongs to the field of safety equipment, and in particular relates to a vehicle safety distance warning device and method based on binocular stereo vision. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, automobiles have entered thousands of households. However, due to the sharp increase in traffic volume, frequent traffic accidents have also caused huge losses to the safety of life and property of the general public. According to statistics from China Daily, more than 60,000 people die in traffic accidents every year in my country, and it has been one of the countries with the largest number of traffic accident deaths in the world for more than ten consecutive years. Some research institutions have found that rear-end collisions account for 35% of the total number of traffic accidents, and more than 60% of highway accidents. [0003] The main...
