The utility model can detect and identify the speed limit signs in road traffic environment in real time, and hint the real speed limit signs in front of the driver through the image display and voice broadcast, so that the vehicle runs within the set speed, thereby the speeding can be reduced, and the traffic safety can be enhanced.
Description
Technical field
The utility model belongs to the vehicle safety driver assistance field of intelligent transportation, particularly based on the safe driver assistance technology of computer vision.
Background technology
Quickening of urbanization process, quickened the change that city road network is built, the locus of stated-speed sign information and the change of attribute information have been caused, simultaneously, actual conditions for comprehensive weather conditions and road conditions, more stated-speed sign is set up to variable stated-speed sign, and these all make the technological means of utilizing GPS location and GIS data query realize that the function of prompting chaufeur the place ahead stated-speed sign can't realize that the supplementary of chaufeur becomes a key factor that improves safety traffic.Still the car-mounted device of not discerning at the detection of traffic sign stated-speed sign occurs in the market.Mostly car-mounted device on the market is at navigation information service, i.e. the location information of determining by GPS, and the road section information in the comparison GIS data bank is pointed out corresponding speed-limiting messages, to reduce the safety that improves violating the regulations.Such device has two major defects, and the one, mostly the Data Update of this type of device is to obtain by the mode of online download, and Data Update is subjected to the restriction in generalized information system database update cycle, can not in time follow the tracks of growing urban highway traffic present situation; The 2nd, this type of device can not provide any useful information at a lot of dynamically changeable speed limit traffic signs that are provided with according to real-time weather condition on the highway section.Therefore active demand has the safe DAS (Driver Assistant System) that can fast automaticly gather, detect identification stated-speed sign attribute information on the market.
Summary of the invention
The purpose of this utility model provides a kind of stated-speed sign information vehicle DAS (Driver Assistant System) based on computer vision, utilize video technique, image processing and mode identification technology with solution, realize detecting in real time, identification traffic stated-speed sign, and utilize image to show and the mode of voice broadcast provides the technical matters of early warning information to chaufeur.
A kind of stated-speed sign information vehicle DAS (Driver Assistant System) based on computer vision described in the utility model realizes that the technical scheme of above-mentioned purpose is as follows:
It mainly is made of in-vehicle processor system, pre-alarming control system and the power-supply system of image capturing system, the identification of confession target detect; Image capturing system is made up of imageing sensor, image pick-up card, the input end of the output termination in-vehicle processor system of image pick-up card; Pre-alarming control system is shown by image and the voice broadcast module is formed, the mouth of the input termination in-vehicle processor system of described image demonstration and voice broadcast module; Described imageing sensor is installed in and detects the vehicle tip position.
Aforesaid a kind of stated-speed sign information vehicle DAS (Driver Assistant System) based on computer vision, described image capturing system is made up of as collecting device the face system of battle formations.
The utility model is for the safe DAS (Driver Assistant System) service development of vehicle.The utility model can realize detecting in real time the function of the stated-speed sign in the identification road traffic environment, and show and the mode of voice broadcast is pointed out the true stated-speed sign in chaufeur the place ahead with image, automobile is travelled in the authorized speed scope, and minimizing is driven over the speed limit, and improves safety traffic.Remedied and utilized GPS (global positioning system Global Positioning System) location and GIS (geographic information system Geographic Information System) data query technique means prompting the place ahead stated-speed sign can not realize to variable speed-limit sign it being the shortcoming of correct report on the market, for the safe driver assistance of chaufeur provides strong technical support and assurance.
Description of drawings
Fig. 1 is a system hardware composition frame chart of the present utility model.
Fig. 2 is an in-vehicle processor systemic-function functional block diagram of the present utility model.
The specific embodiment
The utility model mainly constitutes by being installed in the in-vehicle processor system, image capturing system and pre-alarming control system, the power-supply system etc. that detect on the vehicle.In-vehicle processor system, image capturing system are onboard system equipment, and pre-alarming control system is a human-computer interaction interface, and their hardware component relationship is referring to Fig. 1.Its radical function is by two parts, and one is image acquisition and target detect identification, and another is that early warning shows and report.Wherein the identification of image acquisition and target detect mainly is made up of face battle array vision system and computer processing module thereof.The early warning control module mainly is made up of image display sub-module and voice broadcast submodule.
Its basic functional principle and working process are as follows: the view data of road environment when the face system of battle formations travels as the collecting device collection vehicle, and export the in-vehicle processor system to.Graphics processing unit utilizes the related algorithm of image processing and pattern-recognition, and the stated-speed sign on each two field picture in the image sequence is detected identification.Recognize sign in case detect, to trigger vehicle-mounted image shows and the voice broadcast module, in car, flash the cooresponding stated-speed sign of demonstration with the form of figure, simultaneously also with the form auto alarm of voice, remind chaufeur in the authorized speed scope, to travel, minimizing is driven over the speed limit, and improves safety traffic.
Data sampling sensor and source of early warning are controlled by the in-vehicle processor system.During system works, vehicle at the uniform velocity travels.
Image acquisition and target detect identification module mainly are made up of the graphics processing unit in face battle array vision system and the computer system thereof.Detecting vehicle tip position attachment face array camera system, with image data acquiring in the in-vehicle processor system.The radical function of the graphics processing unit of in-vehicle processor system is seen Fig. 2, the traffic sign in the video image detected automatically and discerns, and recording-related information; Algorithm mainly is made up of following components: preprocessing part carries out processing such as denoising; The Mark Detection part is at first carried out the figure image intensifying; Then the profile information that is communicated with in the image is verified, the candidate region is demarcated; Secondly, verification is carried out in the candidate region of demarcating, judge whether to keep the candidate region as final surveyed area; Last identification division is discerned the candidate region of determining, record attribute information, and trigger the early warning control module.
The early warning control module realizes the function of man-machine interaction, provides speed-limiting messages to chaufeur simultaneously with sound and light dual mode.After detecting and recognizing stated-speed sign, trigger image and show and the voice broadcast module, in car, flash with the form of figure, show corresponding stated-speed sign, also with the form auto alarm of voice, remind chaufeur in the authorized speed scope, to travel simultaneously, minimizing is driven over the speed limit, and improves safety traffic.
