AI Technical Summary

Problems solved by technology

Among them, the use of radar and laser devices is expensive, the system is complex, and the volume is large, and the effect is not good below 200m, and it is easy to cause false alarms when there are multiple targets or at road bends; the transmission speed of ultrasonic waves is greatly affected by temperature. It is suitable for short-distance distance measurement; it will take a long time for the interactive intelligent anti-collision warning system to be widely used and matched with automobiles

Embodiment Construction

[0070] A preferred implementation example of the present invention is described in detail below with reference to the accompanying drawings.

[0071] see figure 2 , the vehicle intelligent alarm method adopts a combination of a longitudinal anti-collision warning method based on monocular vision and an automatic emergency rescue method to prevent rear-end collision accidents, strive for rescue time to reduce casualties, and effectively prevent collision accidents and casualties , Improve vehicle driving safety.

[0072] Such as figure 2 As shown in (a), the longitudinal collision avoidance warning method based on monocular vision is: use a monocular camera to take a series of images in front of the vehicle at a certain interval, and then use a high-speed digital signal processing DSP chip for image analysis on the captured images , image recognition, and image tracking to identify and track the vehicle in front, calculate the distance and relative speed between the vehicle...

Abstract

The invention relates to an on-board intelligent alarming method and a device, wherein, the method combines a longitudinal anti-collision pre-warning method based on the single-eye vision and an accident automatic help-calling method, realizes preventing the rear-end accidents, strives for helping time, reduces injuries and deaths, effectively prevents the collision accidents and personnel deaths caused by the collision, and improves the running safety of the automobile; the device mainly comprises three parts: an on-board terminal, a monitoring center and a user end; the method and the device use the machine vision technique to differentiate the moving vehicles in the front, have high precision and wide visible range, can effectively probe the obstacles, reduce the error reporting possibility and prevent the collision accidents. The method and the device can improve the safety of the vehicle, thus having extremely large application value and prospect.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a monocular vision-based longitudinal anti-collision early warning method, a GPS / GPRS / GIS technology-based accident automatic rescue method, and corresponding devices. Background technique [0002] With the continuous development and progress of human society, the popularization and application of automobiles will become more common and in-depth, and the resulting road traffic safety problems have become a major worldwide problem. According to the research results of Virginia Technology Bureau and NHTSA in 2006, 80% of road traffic accidents are caused by the driver's negligence within 3 seconds before the accident. Among them, 65% of the accidents are caused by car rear-end collisions, and the rest are caused by side collisions and scratches. What is even more regrettable is that after many major traffic accidents, people are often unable to report their location due ...
