Embodiment 1

[0019] like figure 1 As shown, the present invention includes a plurality of cameras for collecting the driver's facial image and the surrounding situation of the vehicle, a video capture card connected to the plurality of cameras, a vehicle GPS speedometer, a speed reducer, a machine vision ranging information processor and fatigue data Processing and control module, wherein the machine vision ranging information processor and the fatigue data processing control module are connected to the alarm unit and the remote monitoring unit at the same time; the described method is used to process the collected facial images and calculate the fatigue based on machine vision analysis method The fatigue data processing control module of the state discrimination index is connected to the video capture card, and the machine vision distance measurement information processor connected to the video capture card for road detection, target recognition and distance measurement is used for the veh...

Embodiment 2

[0022] This embodiment is preferably as follows on the basis of Embodiment 1: the fatigue data processing control module is also connected to a GPS positioning terminal. It can locate the location information of the vehicle, and transmit the information to the remote monitoring unit through the communication network, so as to facilitate the location management of the vehicle in the later stage.

[0023] The fatigue data processing control module includes a DSP processor for calculating the fatigue state discrimination index and vehicle speed monitoring control based on the machine vision analysis method, and an ARM processor for controlling the output of fatigue warning.

[0024]In order to ensure the accuracy of fatigue driving data and the monitoring and control of other vehicle information, it is usually necessary to analyze a large amount of data to determine whether it is fatigue driving. Therefore, two processors are set up here to process different data respectively to f...

Abstract

The invention discloses a vehicle anti-collision terminal based on machine vision. The vehicle anti-collision terminal comprises the components of a plurality of cameras which are used for acquiring the face image of a driver and a vehicle surrounding condition, a video acquisition card which is connected with the plurality of cameras, a vehicle GPS speed meter, a speed reducer, a machine vision ranging information processor and a fatigue data processing control module, wherein the machine vision ranging information processor and the fatigue data processing control module are all connected with an alarm unit and a remote monitoring unit. The fatigue data processing control module is connected with the video acquisition card. The machine vision ranging information processor is connected with the video acquisition card. The fatigue data processing control module is connected with the vehicle GPS speed meter and the speed reducer. According to the vehicle anti-collision terminal, quick and accurate data processing is realized. Not only can fatigue information of a driver and blind area condition be monitored, but also braking and speed reduction can be performed on the vehicle in emergency, thereby preventing accidents caused by improper vehicle speed control.

Description

technical field [0001] The invention relates to the field of early warning, in particular to a vehicle anti-collision terminal based on machine vision. Background technique [0002] Globally, fatigue driving and collisions of large transport vehicles due to complex traffic, large tonnage, large vehicle body, limited vision, and blind spots are the main causes of traffic fatalities. A number of studies at home and abroad have shown that more than 20% of accidents that cause personal injury or even death are caused by fatigue driving. When the driver is tired, his ability to perceive the surrounding environment, judge the situation and control the vehicle will be greatly reduced, and traffic accidents will easily occur. In addition, drivers are also prone to traffic accidents when their vision is limited and there are blind spots. Especially for professional drivers engaged in long-distance passenger and freight driving, railway locomotive driving, engineering vehicle drivin...
