Vehicle anti-collision monitoring system and method

Abstract

The invention discloses a vehicle anti-collision monitoring system and a vehicle anti-collision monitoring method, which are applied to a vehicle. The vehicle comprises a time-of-flight (TOF) camera, a warning lamp, a sound production device and a brake device. The method comprises the following steps of: establishing a three-dimensional (3D) data sample according to data of a shot object which is collected by the TOF camera in advance; controlling the camera to shoot a scene image comprising scene picture information and Z-directional field depth information in the front scene range of the vehicle; performing comparative analysis on the scene image and the 3D data sample; judging whether the distance between the shot object and the vehicle is less than a safe distance; when the distance between the shot object and the vehicle is less than the safe distance, controlling the warning lamp to be switched on and controlling the sound production device to produce warning information so as to remind a driver to take relative risk avoidance measures; and when the driver does not take the relative risk avoidance measures, controlling the brake device to automatically start a braking mechanism so as to reduce the speed of the vehicle, or emergently brake so as to stop the vehicle. By the system and the method, the aim of reducing the incidence rate of a traffic accident of the vehicle can be fulfilled.

Description

technical field [0001] The invention relates to a vehicle monitoring system and method, in particular to a vehicle collision avoidance monitoring system and method. Background technique [0002] According to the survey, most of the accidents of vehicle collisions are caused by the driver's lack of concentration. In these collision accidents, nearly half of the drivers did not even have time to step on the brakes when the accident happened. If it is a collision accident between cars, the driver or passenger in the car can still reduce the damage caused by the accident through the protection of the car body. However, if a car accident affects passers-by, the pedestrians outside the car may cause serious casualties due to the momentary accident of the driver because they do not have any protective tools. When a car accident between such vehicles and pedestrians occurs, the speed of the vehicle is identified as the most important factor affecting the death and injury of the car...

Problems solved by technology

However, the video recording of the image screen cannot actively know the surrounding conditions of the vehicle, and at the same time, the misjudgment rate of analyzing the surrounding conditions of the vehicle with images is relatively high

Before a collision or impact event occurs, the traditional vehicle monitoring system cannot actively remind the driver to take corresponding risk-avoidance measures, nor can it actively intervene in the control system to take related risk-avoidance measures. Passengers in the car get 100% safety guarantee
