Abstract
Complete video intelligent recording instrument for vehicle driving of the present invention is made up of CMOS camera, Flame Image Process and algorithm integrated chip, data processing unit, wireless data output unit, peripheral circuit and digital drive recorder and numeral/video storage unit.It has adopted image recognition technique, changed that existing digital recording is directly perceived, video recording nonrecognition image and not the blindness of analysis image record.The image of the data of sensor acquisition and pattern recognition biosensor analysis is combined use, thoroughly changed the problem that orthodox car registering instrument data are not directly perceived, be not easy to analyze.The present invention has added one " eyes " and one " brain " to registering instrument, makes the data of storage more reasonable.Cun Chu data are to preserve with visual form simultaneously, provide foundation intuitively for analyzing field accident.Also increase auxiliary eyes for simultaneously the driver, remind driver's vehicle-surroundings that the unusual state of Denging is arranged at any time.As the unconscious modified line of driver; Distance away from the car is near excessively; The close car body of object etc. is arranged.While can be write down the absolute distance of on-the-spot dynamic object and this car body and be noted.These all be original automobile travel recorder can't realize.Can utilize simultaneously public network platforms such as GSM, GPRS that the data of preserving are transmitted by wireless network at any time.Can carry out 24 hours true dynamic monitorings to vehicle.
Description
Affiliated technical field
The present invention relates to the automobile drive recorder material, especially video intelligent Control of Automobile Tachographs.
Background technology
The present automobile travel recorder of selling on the market, mainly write down the travel condition data of automobile, be difficult for understanding and identification, and collected information is single with the form of literal or other codes, record is garbage substantially simultaneously, and particularly Ji Lu process is with literal and digital form record.Readable very poor.The analysis of incident and processing bother very much afterwards, and simultaneously, these data legal bases are insufficient.If increase image scene analysis and image storage means, will increase the data acquisition scope and the ability of automobile travel recorder greatly.
Summary of the invention
In order to overcome the deficiency of existing automobile travel recorder, the invention provides a kind of automobile travel recorder that utilizes image recognition technology, this complete video intelligent recording instrument for vehicle driving can allow client vehicles have under the unusual situation with video mode record and storage data in violating the regulations or surrounding enviroment in the process of travelling, to the client provide intuitively, the video image raw data of readability, for analysis afterwards provides the intuitive image data.Video image when only putting down in writing violating the regulations or generation incident or accident has simultaneously been saved storage medium greatly.Under normal condition, still use literal and digital recording data.This invents recordable image can put down in writing the data information that the existing record instrument can't be put down in writing simultaneously.As modified line violating the regulations, make a dash across the red light, the front and back car travel distance surpass the safe distance that the traffic method requires, illegal activities such as the people does not give precedence in the walkway walking are arranged.Particularly can distinguish road speed limit mark.If when travel speed surpasses the speed limit nameplate of road, overspeed violation is noted with video mode, for evidence obtaining furnishes abundant evidence.The storage record length of storage medium meets national standard.
The technical solution adopted for the present invention to solve the technical problems is: the digital automobile Tachographs, and CMOS camera, video image algorithm chip, microprocessor, the data image storage unit, the core is to handle image with integrated image recognition chip.This image recognition chip comprises two 32 bit RISCARM946E CPUs and 4 tunnel visual identification algorithm device.By the CMOS camera with 40
0X30
0Image in 70 meters of the radiuses through the image recognition chip calculation process after, again by microprocessor the information that the needs processing of classifying.It is characterized in that: on the basis that keeps former digital automobile Tachographs, increase image recognition technology and wireless transmitting unit.When record of travelling that needs are inquired about this car, the visitor can send back to supvr or law-executor to image information and Word message at any time by GSM or GPRS network, also can regularly send back to command centre to the record that travels of every day simultaneously, so that supvr or law-executor at any time, in real time, regularly grasp the transport condition of this car.Simultaneously can insert automobile CAN-bus easily.Easy for installation.
Beneficial effect of the present invention: introduced image recognition technology and Radio Transmission Technology, the important information that existing digital automobile Tachographs can't be detected realizes that by image recognition technology the while can be at any time writing down to such an extent that information is beamed back supvr and law-executor with wireless mode.And all processes of violating the regulations with the image mode record intuitively or incident.The data that make record all are valid data, have saved storage resources greatly.Record effect all is on-the-spot actual effect.Come into plain view.
Description of drawings
Fig. 1 is a composition frame chart of the present invention.
Fig. 2 is acp chip EyeQ (2) theory diagram that the present invention examines employing.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
Consult Fig. 1, composition frame chart of the present invention, complete video intelligent recording instrument for vehicle driving, CMOS camera (1), Flame Image Process and algorithm device (2), data processing unit (3), wireless transmit output unit (4), peripheral circuit (5), digital drive recorder (6) and data storage unit (7) are formed, and it is characterized in that: Flame Image Process and algorithm device (2).
Consult Fig. 2.Core component schematic diagram of the invention process, integrated two 32bit RISC ARM946E CPUs of described Flame Image Process and algorithm device (2) and 4 tunnel visual identification algorithm device have CAN bus network interface and RS232 Asynchronous Serial Interface simultaneously.Itself have 8M flash memory and 32M SDRAM as memory buffer.It is an integrated IC.Now the product type of Shi Yonging is the EyeQ1 that ST Microelectronics produces, and EyeQ 2 also can use in addition.
Principle of work: digital automobile drive recorder (6) and Flame Image Process and algorithm device (2) are in abnomal condition following time at the identification automobile, store relevant vehicle condition information by numeral and image storage unit 7.Sensor in CMOS camera lens 1 and the digital drive recorder 6 is finished the collecting work of data, reads the user mode parameter and the peripheral image document of automobile; When detecting the state of breaking rules and regulations, begin to store data, after violating the regulations the disappearance, stop record.Send alarm signal simultaneously, remind the driver to correct state violating the regulations.When surpassing the velocity amplitude that image detection arrives, remind the driver immediately as speed; When breaking rules and regulations modified line; Cross nearly grade with the place ahead spacing and will send caution to the driver.
When record of travelling that needs are consulted automobile, can directly from data storage unit 7, read written record and the photologging stored and be transmitted into receiving terminal by wireless transmit output unit 4 with wireless mode, do not need to connect people and circuit, can in the area of GSM or GPRS covering, receive data at any time to the data of travelling of want automobile.Because the content of record is all used the videograph mode, this helps to understand the real conditions in the driving process.The state in all vehicle traveling processes also can be selected to write down in omnidistance if desired record.Because memory span restriction, the data of record are to cover the record of the most preceding time.
