Description

Reader seat management device

technical field

The invention relates to the application of a camera, in particular to a camera application device for reader seat management in a library. the

Background technique

At present, as the number of university enrollments increases year by year, when the semester is approaching the exam, many school library study rooms are full of seats. However, it often occurs that some people occupy seats with objects and do not use them for a long time, while other students cannot find seats. In order to solve this phenomenon of occupying seats, various libraries have released various library seat management devices or methods. There are mainly three advanced or mainstream application schemes, namely the infrared sensing method, the method of allocating seats with the campus card, and the method of sending number plates. However, these three types of programs all require students to participate consciously. If some students do not consciously, the phenomenon of occupying seats still exists. In other words, these three methods are highly likely to be subject to human interference. the

Contents of the invention

In order to overcome the disadvantage that the existing three types of methods are highly likely to be disturbed by human beings, the present invention provides a reader seat management device in a library, which uses reader human type recognition technology for library seat management. The device can objectively judge whether there are people in the seat without being disturbed by human beings, and can solve the phenomenon of disorderly occupation of seats in the library. the

In the present invention, the technical solution for achieving the goal is: a camera control system, a reader human-type recognition system, a lens, and a stepping motor are combined into one. The characteristics of the technical solution adopted are: the camera control system is composed of motor servo circuit, lens adjustment circuit, MSP (Mixed Signal Processor, mixed signal processor, single-chip microcomputer) 1, USP; the reader human type recognition system is composed of interface circuit, MSP2, FLASH, SRAM, display and image CCD (image sensor); among them, the stepper motor, motor servo circuit is connected in series with MSP1, the lens and lens adjustment circuit are connected in series with MSP1, and MSP1 is connected with USB; MSP1 is connected with MSP2 through the interface circuit; MSP2 It is connected with SRAM, FLASH, display, image CCD and interface circuit, and the image CCD is connected with lens and interface circuit respectively; the stepper motor is connected with lens through a rotating shaft. the

The reader seat management implementation method of the reader seat management device is as follows:

First of all, before use, the lens is controlled by MSP1; in addition, the image CCD is controlled by the interface circuit to read various possible human-type images of readers in the library, and the original image is preliminarily processed. Execute the library building program of the reader's humanoid image database, establish fingerprint-like characteristic data through the reader's humanoid image module, store it in the reader's humanoid image database, and save the reader's humanoid characteristic image model. the

In real-time use, the MSP2 controls the image CCD to capture the reader's humanoid image, process it, and then transmit the real-time reader's humanoid image data to MSP1, and then match it with the reader's humanoid feature image template in the reader's humanoid image database. In order to realize the human image recognition of readers. Judging whether there is someone in the seat, and then recording, counting and saving the judgment result. And the seat utilization is displayed on the monitor. the

The beneficial effect of the invention is that it can solve the phenomenon of randomly occupying seats in a library, provide a fair and orderly reading environment for readers, and reduce the workload of librarians. Moreover, this is also the direction of development in the technical field of digital video cameras, and has practicality and promotional value. the

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing Fig. 1 and embodiment. the

In Figure 1, three circuits are included. The first circuit is: stepper motor, motor servo circuit, MSP1 in series, the function of this circuit is: MSP1 controls the precise rotation of the stepper motor. The second circuit is: lens, lens adjustment circuit, MSP1 series connection, it controls the switch of lens gathering and shutter. The third circuit is: lens, image CCD, MSP2 and other connections. The function of this circuit is to transmit the image information from the lens to MSP2 for processing and analysis, and cooperate to complete the reader's human type recognition. the

The database module and feature matching function of the reader seat management device are realized by the MSP1 of the camera control system; the collection, image processing and feature extraction of the reader's humanoid image are completed by the MSP2 of the reader's humanoid recognition system. the

MSP2 can store temporary reader figure image into SRAM. After the interface circuit collects an image, it notifies MSP2 that the data is ready. When processing data, MSP2 fetches the SRAM data into its internal RAM, performs reader image processing and feature extraction, and then MSP2 sends the reader image model, through the interface circuit, and the reader image in MSP1 Characteristic human types in the library are matched. Finally, the results are recorded, calculated, stored, and displayed. the

When actually working, first an image is taken by the lens, and then the lens is driven by a stepping motor to rotate at a certain angle, and then another image is taken. When the motor rotates a circle, the lens will capture the images of a circle. and continue continuously. At the same time, the image processing module continuously analyzes the image to determine whether there are people in each seat, and can perform related calculations and store the results. Once it is found that a seat has been occupied for a long time, it will be displayed and the administrator can be reminded to investigate. the

The system allocates storage resources reasonably. System external memory includes FLASH and SRAM. The program modules related to image acquisition, processing and feature extraction are placed in FLASH, the temporary reader image data during the algorithm operation is stored in off-chip SRAM, and the final reader image features are stored in FLASH. the
