Abstract

The invention relates to an intelligent vehicle device and a method for preventing collision to a passerby in the technical field of vehicle automatic control, wherein the device comprises a binocular pinhole camera, a signal processor, a vehicle speed control mechanism and a sound prompting device; the method comprises the following steps of: 1. calibrating a camera parameter; 2. synthesizing a left view and a right view; 3. judging and determining the positioned region of a moving object; 4. computing a threshold value overcoming a grey-level difference; 5. measuring similarity; 6. detecting the distance between the moving object and a vehicle; 7. outputting a control instruction; and 8. repeating the cycle process from step 2 to step 7. The device and the method can be used for automatically detecting road surface conditions, and once the passerby is found, the device can immediately issue a control instruction, warn a driver to pay attention to forward road conditions and automatically enable the vehicle to decelerate and brake, thereby enhancing the automated and intellectualized technical levels of the vehicle and ensuring driving safety.

Description

technical field [0001] The present invention relates to a device and method in the technical field of automatic control, in particular to an intelligent device and method for avoiding collisions between automobiles and pedestrians. Background technique [0002] Vehicles running on the road will inevitably encounter pedestrians crossing the road or other obstacles. As we all know, because of the negligence of drivers, catastrophes often result, especially when pedestrians cross urban road zebra crossings or cross country roads. To completely eradicate the occurrence of such traffic accidents, it is very important to improve the level of automation and intelligent technology of vehicles. Vehicle intelligent collision avoidance technology based on image information is one of the effective means. [0003] After searching the existing technical documents, it was found that Wang Yuntao's invention patent "automobile active and passive protection inflatable anti-collision airbag"...
