The specific embodiment

Below with the specific embodiment and combine accompanying drawing that automotive theft proof system and method that embodiment of the present invention provides are done further explain.

See also Fig. 1, the automotive theft proof system of embodiment of the present invention is used for automobile is carried out anti-theft protection.Automotive theft proof system 10 comprises startup module 12, image collection module 14, registration database 16 and microprocessor 17.Registration database 16 is connected to microprocessor 17.Microprocessor 17 comprises analyses and comparison module 18 and judge module 19.

Start the image collection module 14 that module 12 is used to start automotive theft proof system 10, image collection module 14 is started working.In this embodiment, start module 12 and link to each other, when the people spurs automobile door handle and attempts to open car door, can start image collection module 14 and carry out work with automobile door handle.Be appreciated that starting module 12 also can be infrared inductor, can start image collection module 14 when in infrared inductor is sensed apart from the car door predeterminable range, having the people to occur.

Image collection module 14 can be arranged in the automobile, and it comprises photographic camera (figure does not show), is used for carrying out scan camera shooting to triggering the user's pupil of both eyes that starts module 12.Image collection module 14 also can further comprise an illumination equipment (figure does not show), the pupil image of camera this moment under the illumination equipment irradiation.Illumination equipment can be infrared illumination, and clearly to shoot the detail textures of pupil, infrared light supply is invisible simultaneously, can not produce the dazzling uncomfortable sensation that waits to the user.Further, image collection module 14 also can comprise apparatus for adjusting position (figure does not show), and the angle of adjusting photographic camera and illumination equipment according to user's height and present position automatically makes photographic camera and illumination equipment aim at user's pupil.The Illumination intensity of scalable illumination equipment when utilizing 14 pairs of user's pupil of both eyes of image collection module to take pictures, and then photographic camera can absorb a series of pupil image.Such as, illumination equipment is the light source by the periodicity flicker of software control, with the motion (shrinking or expansion) that stimulates pupil.Certainly, when the Illumination intensity of illumination equipment is non-adjustable, also can only absorb one or more pupil image under the same Illumination intensity.Be appreciated that image collection module 14 also can be arranged at a certain position of vehicle body near car door.

Registration database 16 is used to store the pupil image of the legal chaufeur that the automobile car owner approved, is stored with the pupil image that the automobile car owner utilizes all legal chaufeurs of image collection module 14 picked-ups in advance.

Microprocessor 17 links to each other with automotive control system (figure does not show), with Control of Automobile release and startup car engine.

The one or more image that analyses and comparison module 18 is used for image collection module 14 is absorbed compares with the pupil image of registration database 16 successively.This comparison refers to pupil and the similarity between the pupil in the registration database 16 in the computed image.

Judge module 19 is used for judging the pupil whether registration database 16 exists the pupil that absorbed with image collection module 14 to conform to.Particularly; If the similarity between pupil image that image collection module 14 is absorbed and the some pupil image in the registration database 16 is more than or equal to the threshold values of setting; Then judge module 19 is judged the pupil that existence conforms in the registration database 16, car door release.If the similarity between pupil image that image collection module 14 is absorbed and the pupil image in the registration database 16 is all less than the threshold values of setting; Then do not have the pupil that conforms in the judge module 19 judgement registration databases 16, the pupil image that storage is absorbed is as the usefulness of consulting.

See also Fig. 2, a kind of automobile anti-theft method is used for automobile is carried out anti-theft protection.This automobile comprises automotive theft proof system 10.It may further comprise the steps this automobile anti-theft method:

Step S201 sets up registration database 16, and the pupil image of the legal chaufeur that the automobile car owner is approved is stored in the registration database 16.

Step S202 obtains pupil image.When obtaining this pupil image, can absorb user's pupil image by starting module 12 triggering image collection module 14 near this automobile.When pulling Door Handle as the user and attempt to open car door, start module 12 and can trigger image collection module 14 and carry out work.

Step S203 is with the analysis that compares of the pupil image in the pupil image of being obtained and the registration database 16.Compare of analysis utilization analyses and comparison module 18 is carried out, and comparison refers to pupil and the similarity between the pupil image in the registration database 16 in the computed image.

Step S204 judges whether there is the pupil that conforms to the pupil of institute pickup image in the registration database 16.Particularly: if pupil image that image collection module 14 is absorbed and the similarity between the pupil image in the registration database 16 are all less than the threshold values of setting; Then there is not the pupil that conforms to, execution in step S205 in the judge module 19 judgement registration databases 16.If the similarity between pupil image that image collection module 14 is absorbed and a certain pupil image in the registration database 16 is more than or equal to the threshold values of setting, then judge module 19 is judged the pupil that existence conforms in the registration database 16, execution in step S206.

Step S205, the pupil image that storage is absorbed is as the usefulness of consulting.

Step S206, the car door release.

Step S207, whether the inquiry user starts car engine and vehicle electric power system.If the user selects, execution in step S208, otherwise finish.

Step S208 starts car engine and electric system.

This automotive theft proof system 10 and automobile anti-theft method are through gathering the pupil image near user vehicle; And the pupil image of the legal chaufeur that this pupil image and automobile car owner are approved is analysed and compared and is judged whether that automobile is carried out release to be handled, and can avoid the offender to pass through the car theft key and car theft.The car owner also need not carry automobile key.

In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, these all should be included in the present invention's scope required for protection according to the variation that the present invention's spirit is done.
