The course of work of the present utility model is divided into seven steps:
The first step: infrared depth camera simulates the video camera of two diverse locations and angle by the slip on guide rail, calibrates the effective focal length of video camera, completes the surveying work of distance;
Second step: in the time that vehicle enters, the Infrared image obtaining by infrared camera carries out binaryzation and threshold valuesization operation, orients vehicle location;
The 3rd step: select Marker Detection algorithm, carry out the locational square frame figure of search vehicle, thereby come positioning licence plate position.；
The 4th step: estimate the windup-degree of car plate by infrared depth image, and proofread and correct its angle;
The 5th step: the car plate of proofreading and correct is carried out to character and cut apart, template matches;
The 6th step: report the number-plate number obtaining, allow car owner confirm, and store;
The 7th step: voice-input device is monitored car owner's direction sound, other directions is carried out to noise reduction, and use voice interactive system to answer car owner problem, and manual service platform is monitored at random, and to requiring the client of manual service, manually replys.
The beneficial effects of the utility model are: by the grasp to measuring technique and mathematical model method, voice system and car plate are automatically identified and carried out the system integration, structurally adopt the industrialization design of DSP two-shipper high-speed computation, made our equipment can make packaged type or portable.Can make up the deficiency of the fixed vehicle access management system of current employing, adopt intelligent control algorithm very effective for reducing the error of measuring simultaneously, make our product can become low cost, removable, high-precision electronic service person.
