In the technology of number plate recognition, as mentioned above, obtaining image by driving recording module will first be temporary in the internal memory of system, and judge whether that vehicle enters the scope of image acquisition according to image, and calculate vehicle distances in real time, if the time in that distance being less than a safety distance, the program of wherein licence plate identification will be started, comprise image compensation, sharpened, seek limit, the steps such as correction, be identification number after finding car plate position, identification result can be presented on drive recorder telltale, even when particular event occurs, picture and identification result can be sent to specific objective by means of communication.
Lane departure module 507 is similarly the image captured by photographing module 503 utilized in driving recording module 505, vehicle driving road is picked out according to the lines be plotted on road such as driving lane sign, curb sign on road in image, and the distance relation calculated in real time between vehicle and each lines, therefore judge departure distance according to vehicle with the relative position in track picked out and send warning, display screen as by the sound, driving recording module 505 shows alarm signal, because the danger of vehicle shift road under avoiding being driven in automatic situation.
Distance measurement function module 508 in order to judge the distance of vehicle and front truck or rear car, can such as utilize the modes such as light (as infrared light, laser light), radio.Coordinate in an embodiment of driving recording module 505 in the present invention, can also judge, with the distance of front truck, such as to judge the change of front truck or rear car image before and after a period of time, distance can be judged accordingly in the image captured by above-mentioned photographing module 503.
Night vision function module 509 is can by software approach, or the function of image procossing strengthened by hardware, therefore coordinates driving recording module 505, strengthens the night vision function of wherein photographing module 503 by image procossing.
Collision prevention function module 510 can coordinate the image of the real-time fore-aft vehicle acquired by driving recording module 505, also the vehicle image change in a period of time can be obtained according to distance measurement function module 508, change and fore-aft vehicle speed with the distance obtained in a period of time, referring again to this car speed of a motor vehicle, when the change of this distance within the time is greater than a door, a crashproof signal will be sent, remind driver to have the possibility of collision by modes such as the sound, image displays.
It is worth mentioning that, the script of above-mentioned cooperation driving system or the equipment carried additionally in addition (as display equipment, photographing module) the driving recording module 505, number plate recognition module 506, lane departure module 507, distance measurement function module 508, night vision function module 509 and the collision prevention function module 510 that provide, or wherein individually can in hardware carry on modularization driving system, the such as enlargement module daughter board 301 of Fig. 3 display, 302,303; Can be maybe software enlargement module, the expansion control module 40(namely in driving system be as shown in Figure 4) in multiple extended interfaces at least can comprise a software extended interface, can in order to expand one or more with the enlargement module of software simulating.
Therefore software extended interface can be provided with the expansion of connection one computer installation executive software and upgrade interface unit 403(as shown in Figure 4 with upgrade one), general as USB (USB), live wire (Firewire), bluetooth (Bluetooth
tM) or WiFi
tMat interface.
One of method step that Fig. 6 display application operates in modularization driving system of the present invention.
In this instance, start as S601, modularization driving system along with after vehicle launch also along with startup, but this modularization driving system more can independent of vehicle launch energy independent operating, therefore not limited.
After startup, as S603, modularization driving system scanning enlargement module, system can grasp the software or hardware expansion module that can operate at present, and after the function of all enlargement modules being integrated, dynamic load extended interface definition (S605), therefore can provide function to switch and control menu (S607).That is, modularization driving system can be in the various function button definition in system originally along with the attribute dynamic conditioning of enlargement module in system, when user starts specific enlargement module, display operation-interface on the display screen and related key define can along with adjustment.
Then, again for Fig. 7, when enlargement module has variation, such as newly-increased enlargement module, system can define according to newly-increased module adjustment aforementioned operation interface and each function button.The method step of modularization driving system running comprises when detecting when newly-increased enlargement module (S701), system is by newly-increased for loading extended interface (S703), this part interface can be provided by enlargement module, or additional downloads is installed, the function of corresponding specific enlargement module therefore can be provided to switch and control menu (S705).
To sum up, disclosed modularization driving system is a kind of open-ended driving system, and system can provide corresponding operating environment according to the attribute of enlargement module, expansion control module in system has multiple extended interface, comprise the extended interface of software restraint, make the technology of the present invention can carry out image processing and analysis by the image acquired by driving recording module, the functions such as the judgement of real-time front-and-rear vehicle distance, licence plate identification, lane departure warning, night vision, anti-collision alarm can be provided.
The foregoing is only better possible embodiments of the present invention, not thereby namely limit to the scope of the claims of the present invention, the equivalent structure that therefore everything uses specification sheets of the present invention and diagramatic content to do changes, and is all in like manner included within the scope of the present invention.
