Camera based traffic light and zebra crossing recognizing and control system

Abstract

The invention discloses a camera based traffic light and zebra crossing recognizing and control system. The system comprises a host computer, and a video recognizing device which is connected to the host computer, wherein the video recognizing device is used for shooting the image of a road in front of a vehicle and determining whether a traffic light and a zebra crossing exist in front of the vehicle or not; if so, the state of the traffic light is recognized, and the real-time space distance from the vehicle to the traffic light and the zebra crossing can be calculated according to the pixel value of the traffic light and the zebra crossing in the video and image, and the continuous-reducing space distance value is sent to the host computer; the host computer can be used for comparing the continuous-reducing space distance value between the vehicle and the zebra crossing according to the traffic light state information and based on the preset red light running distance critical value, so as to determine whether the vehicle runs the red light or not. According to the system, the real-time space distance from the vehicle to the traffic light and the zebra crossing is calculated based on the image pixel value, and the behavior of a driver driving the red light can be prevented and stopped, and as a result, the traffic order can be preserved.

Description

technical field [0001] The invention belongs to the technical field of engineering vehicle management, and relates to a traffic light and zebra crossing recognition and control system based on a camera device. Background technique [0002] At present, many cities in China are building or planning to build subway transportation facilities. In order to solve the contradiction between the uncoordinated development of mining machinery and transportation machinery in subway shield construction, a large number of vehicles for transporting muck, mud and other sundries are needed. Nighttime driving of muck trucks, overloading, unsealed transportation, and illegal driving are common problems across the country, and they have also become one of the chronic problems of urban management. This phenomenon has not been resolved for a long time, seriously polluting the urban environment and disrupting traffic order. , disrupting the lives of residents. [0003] At present, the supervision ...

AI Technical Summary

Problems solved by technology

However, in the field of muck trucks, the weight of the vehicle is as high as 40 to 50 tons, and it cannot be directly braked. Instead, it is necessary to perform speed limit control after judging the behavior of running a red light, or a lock control that cannot be started again after the ACC is turned off.

At the same time, the zebra crossings on many suburban roads where muck is transported are not obvious or have no zebra crossings, making it difficult to identify zebra crossings
