Abstract

The invention relates to a reader seat management device in a library. According to the reader seat management device, the reader human shape recognition technology is applied to a camera. The reader seat management device is characterized in that the camera is made to acquire characteristic information such as the human shape and the sitting posture shape of a reader on each seat in the library, and the human shapes and the sitting posture shapes serve as the analyzed subject, so that whether each seat has a person to sit on or not is determined, recorded, calculated or displayed. The position angle of a lens can be rotated for all-directional monitoring. The reader seat management device has the advantages that the problem that the seats in the library are occupied arbitrarily can be solved, a fair and orderly reading environment is provided for the readers, and workloads of librarians can be relieved. Moreover, the reader seat management device shows the development trend in the technical field of cameras and has practicability and promotional value. The reader seat management system is characterized by being composed of a camera control system, a reader human shape recognition system, the lens and a stepping motor, wherein the camera control system is composed of a motor servo circuit, a lens regulating circuit, an MSP1 and a USP, and the reader human shape recognition system is composed of an interface circuit, an MSP2, a FLASH, an SRAM, a displayer and an image CCD.

Description

Reader seat management devices

Technical field

The present invention relates to the application of video camera, particularly the camera application device of library users seat management.

Background technology

At present, along with college enrollment number increases year by year, when term is close to the examination, many school library room for individual study is had no empty seat.But often have people with article account for seat for a long time need not and other classmates can not find the phenomenon at seat.In order to solve a this phenomenon that accounts for, each library has released various library seat management devices or method one after another.It mainly contains the application scheme of three kinds of more advanced or main flows, the method for infrared induction method, all-in-one campus card seat allocation, send the method for number plate.But this 3 class scheme all needs the conscious participation of student, unconscious if any indivedual students, account for a phenomenon and still exist.This 3 method is subject to the possibility of artificial interference very large in other words.

Summary of the invention

Be subject to the very large deficiency of possibility of artificial interference in order to overcome existing 3 class methods, the invention provides a kind of reader seat management devices of library, human-like reader recognition technology is managed for seat, library.This device can not be subject to artificial interference, judges objectively and on its seat, whether has people, can solve the phenomenon at Luan Zhan seat, library.

The present invention, for the technical scheme of realize target is: be combined into one by camera control system, the human-like recognition system of reader, camera lens, stepper motor.The feature of the technical scheme adopting is: camera control system is by motor servo circuit, camera adjusting circuit, MSP (Mixed Signal Processor, mixed-signal processor, single-chip microcomputer) 1, USP composition; The human-like recognition system of reader is made up of interface circuit, MSP2, FLASH, SRAM, display and image C CD (imageing sensor); Wherein, stepper motor, motor servo circuit are connected with MSP1, and camera lens, camera adjusting circuit are connected with MSP1, and MSP1 is connected with USB; MSP1 is connected with MSP2 by interface circuit; MSP2 is connected with SRAM, FLASH, display, image C CD and interface circuit, and image C CD is connected respectively with camera lens, interface circuit; Between stepper motor and camera lens, be connected by a rotation axis.

The reader seat management implementation method of reader seat management devices is as follows:

First, before using, by MSP1 regulation and control camera lens; Another process interface circuit control chart reads the various possible human-like image of reader in library as CCD, and original image is carried out to rough handling.Carry out again the library of building of the human-like image data base of reader, by the human-like image module of reader, set up finger-print type characteristic, deposit the human-like image data base of reader in, preserve reader human-like characteristic image mould and pull.

In using in real time, take the human-like image of reader by MSP2 control chart as CCD, processing is processed, more human-like real-time reader view data is passed to MSP1, then pull and mate with the human-like characteristic image mould of reader in the human-like image data base of reader, to realize the human-like image recognition of reader.Judge on its seat, whether there is people, then by judged result record, counting, preserve.And utilize situation to show on display at seat.

The invention has the beneficial effects as follows, can solve Luan Zhan seat, library phenomenon, for reader provides a reading environment that justice is orderly, and alleviate librarian's work load.And this is also the direction of Digital Video technical field development, has practicality and promotional value.

Brief description of the drawings

Fig. 1, circuit block diagram of the present invention.

Embodiment

Below in conjunction with accompanying drawing Fig. 1 and embodiment, the present invention is further described.

In Fig. 1, comprise three circuit.Article 1, circuit is: stepper motor, motor servo circuit, MSP1 series connection, the function of this circuit is: MSP1 control step motor accurately rotates.Article 2 circuit is: camera lens, camera adjusting circuit, MSP1 series connection, it is controlled, and camera lens is assembled and the switch of shutter.Article 3 circuit is: the connections such as camera lens, image C CD, MSP2, the function on this road is that the image information of being come by camera lens is delivered to MSP2, carries out Treatment Analysis, has coordinated the human-like identification of reader.

The database module of reader seat management devices and characteristic matching function, realized by the MSP1 of camera control system; Collection, the image of the human-like image of reader are processed and characteristic extraction procedure, are completed by the MSP2 of the human-like recognition system of reader.

MSP2 can store human-like interim reader image in SRAM into.Interface circuit is gathering after piece image, and notice MSP2 data are ready to.In the time of deal with data, MSP2 gets SRAM data in its inner RAM, carries out the human-like image of reader and processes and feature extraction, then send the human-like image mould of reader by MSP2 and pull, through interface circuit, with human-like coupling of feature in the human-like image library of reader in MSP1.Finally by outcome record, calculating, storage, and can show.

In the time of real work, first by lens shooting one image, then make camera lens rotate to an angle under stepper motor drives, then take another image.In the time of electric machine rotation one week, camera lens is all filmed the image of a week.And go on continuously.Meanwhile, image processing module is analysis image ceaselessly, judges on each seat, whether there is people, and can carry out correlation computations, stores its result.One when finding that certain seat, for a long time by the occupation of land follwed by nonuse of it, will show, and can remind keeper to go investigation.

Native system has carried out reasonable distribution to storage resources.System external memory storage comprises FLASH and SRAM.About the program module of collection, processing and the feature extraction of image is placed in FLASH, the human-like view data of interim reader in algorithm operational process is deposited in the outer SRAM of sheet, and the human-like characteristics of image of last reader is deposited in FLASH.
