Embodiment Construction

[0055] The technical scheme of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0056] Such as figure 1 As shown, the device for emergency handling of vehicle driving based on stereo vision includes a binocular vision camera unit, a vehicle-mounted bus interface, a central processing unit, a vehicle brake control system, and a sound and light warning circuit. among them,

[0057] The binocular vision camera unit includes two CCD digital color cameras of the same model, a digital video output interface and a camera mounting bracket. The two cameras are fixed on the same bracket and installed on the top of the vehicle or behind the windshield, such as figure 2 with image 3 Shown

[0058] The central processing unit includes a DSP central processing unit, memory, digital video input interface, vehicle sensor bus interface, vehicle brake control system interface and alarm information output interface. The central process...

Abstract

The invention relates to a stereoscopic vision based emergency treatment device and method for running vehicles, wherein the device comprises a binocular-vision image pick-up unit, an on-board bus interface, a central processing unit, a vehicle braking control system and an acousto-optic alarm circuit. The binocular-vision image pick-up unit is used for capturing an image of a road in front of a vehicle; the DSP (digital signal processor) based central processing unit is adopted for carrying out real-time quick calculation on a visual image so as to obtain a three-dimensional road scene, and compares the obtained three-dimensional road scene with a safe driving road model set up by a system so as to judge whether obstacles or dangers exist in the traveling direction of the vehicle; when adanger is found, the vehicle braking control system is started so as to reduce the speed of the vehicle and send an acousto-optic alarm to a driver; meanwhile, the central processing unit is connected with a vehicle sensor by an inter-vehicle bus so as to detect the state of the vehicle, and when the vehicle has mechanical or circuit faults, a braking system is started so as to reduce the speed of the vehicle and send an acousto-optic alarm. The device disclosed by the invention can be arranged on ordinary motor vehicles so as to avoid the occurrence of accidents or reduce the accident loss, thereby improving the driving safety performance.

Description

Technical field [0001] The invention relates to the field of active and safe driving of automobiles, in particular to a vehicle driving emergency processing device and an implementation method based on stereo vision image processing. Background technique [0002] The development of automobile technology has brought convenience to transportation and people's lives, but the occurrence of road traffic accidents has caused huge losses to people's lives and property and the national economy. In order to solve the negative impact of vehicle traffic, people are actively seeking to adopt high technology to improve vehicle performance. As a component of Intelligent Transportation System (ITS), vehicle safety assistance systems, advanced vehicle control systems, and automatic vehicle driving systems have become current research areas. Focus. Advanced Vehicle System (Advanced Vehicle System) refers to the use of on-board equipment, road testing, and road electronic equipment to detect cha...
