Vision-based distance measurement, rear-end collision early warning and on-board safety vehicle device

Abstract

The invention discloses a vision-based distance measurement, rear-end collision early warning and on-board safety vehicle device, which comprises a camera distance measurement module installed on a vehicle front bumper, and a CPU processor, a positioning module, an alcohol detection module, a message sending module, a storage module, a wireless communication module, a display module and a voice alarm module which are installed in a vehicle. The vision-based distance measurement, rear-end collision early warning and on-board safety vehicle device has the beneficial effects that the gas alcohol concentration in the vehicle can be detected, and thus drunken driving is decreased; the distance and speed are measured, the identity of the vehicle ahead is recognized and the communication is built, and thus drivers of the both sides are reminded of paying attention to driving safety; and positioning data and driving information of the vehicle per se are recorded in real time, the driver of the vehicle ahead can be reminded of taking an appropriate measure to avoid in real time, the effect of two-way defense is achieved, and the driving safety is effectively improved.

Description

technical field [0001] The invention relates to the field of automobile active defense safety, in particular to a vision-based device for vehicle distance detection, rear-end collision warning and vehicle safety. Background technique [0002] With the development of society, the number of automobiles has increased year by year, and the expressway has also developed rapidly. However, traffic accidents caused by drunk driving are increasing; at the same time, the speed of automobiles on the expressway is fast. Sudden braking is required. Due to the longer braking distance and longer reaction speed, accidents such as rear-end collisions are prone to occur. Some developed countries, such as the United States, Japan, Germany, etc., have started the research and development of vehicle active defense devices more than ten years ago, but the corresponding technology in my country started relatively late, and most of them still stay on passive defense devices. The current anti-fog l...

AI Technical Summary

Problems solved by technology

The current anti-fog lights and warning lights also belong to the category of passive defense products, and the effective distance of such products is also very limited. For vehicles running at high speed, it is difficult for the driver to completely Control the vehicle, which will also cause great loss to life and property
