Abstract
The present invention provides an information acquisition system, including acquisition subsystem and data management subsystem. The acquisition subsystem includes a digital camera shooting module for controlling digital camera to collect personal photograph information; an image compression module for compressing photograph; a fingerprint acquisition module for controlling scanner to collect same fingerprint for several times and integrating characteristic information of fingerprinting image; and a fingerprint comparison module for comparing some fingerprint information and providing optimum fingerprint. The data management subsystem includes an information storage module and an information inquiry module.
Description
Technical field
The present invention relates to individualized technical field, relate in particular to a kind of information acquisition system in the individualized technology.
Background technology
Existing information acquisition system mainly is that photo, fingerprint and the personal information to the individual gathered and record.The main weak point of information acquisition system is the arrangement requirement height to the collection point at present, need understand that the staff of portraiture photography uses; The compression quality that is comparison film in addition is not high, and for generally needing comparison film to compress after the large-scale information acquisition, but existing acquisition system tends to influence the quality of photo.
Summary of the invention
Fundamental purpose of the present invention is to have proposed a kind of information acquisition system, the requirement of photo compression when having reduced to collection point staff's requirement and extensive the collection, make the space of database can fully obtain utilizing, also reduced investment simultaneously memory device.
The present invention is achieved in that
A kind of information acquisition system comprises acquisition subsystem and data administration subsystem.
This acquisition subsystem comprises a digital camera taking module, and the may command digital camera is adjusted the acquisition parameters that comprises color balance and diaphragm shutter automatically, is used to control the photographic intelligence that digital camera is gathered the individual.Digital camera directly is connected with computing machine, whenever takes just its shooting effect as can be seen of a photo, as facial expression not to or effect bad, it can be deleted, and retake then and there.This digital camera taking module also can directly cut after photo is sent to computing machine, can freely adjust size, the position of trim box, and preview simultaneously cuts effect.
This acquisition system also comprises an image compression module, is used to compress the photo that this digital camera is taken.This image compression module judges earlier whether the photographic quality that digital camera is taken meets contractive condition, and the photo that will meet contractive condition is compressed to less than 10k, and photo is also encrypted with cryptographic algorithm it after the overcompression processing.
This acquisition system also comprises a finger print acquisition module, and gated sweep instrument number of times is gathered same fingerprint, gathers the characteristic information of fingerprint image.This finger print acquisition module directly is connected with the living body finger print identifier, obtains the digital information of vital fingerprint image from the living body finger print identifier, and passes through the characteristic of system software Automatic Extraction fingerprint image.The characteristic of fingerprint image is stored in it in database of system by this information storage module after compression.This finger print acquisition module is also preserved the raw digitized information of vital fingerprint image.
This acquisition subsystem also comprises a fingerprint comparison module, certain finger print information of scanner collection is compared, and extract finger print information the best in quality.
This data administration subsystem comprises
One information storage module is used for the information stores that will the collect database to this system;
One information inquiry module is used for inquiring about the record of described database;
One statistics of database module is used for the record of database is added up.
As from the foregoing, this information acquisition system has reduced the complexity of former acquisition system to operating personnel, computer technology, portraiture photography skill, has improved work efficiency greatly; Taken pictures by computer control, the quality of comparison film has also had guarantee; Under the prerequisite that guarantees photographic quality, use advanced photo compress technique simultaneously, saved the capacity of database greatly.
Embodiment
The present invention is further illustrated below in conjunction with embodiment.
A kind of information acquisition system comprises acquisition subsystem and data administration subsystem.
This acquisition subsystem comprises a digital camera taking module, and the may command digital camera is adjusted the acquisition parameters that comprises color balance and diaphragm shutter automatically.When the computer controlled automatic camera was taken, utility appliance synchronous workings such as automatic control lamp light also can be simulated various types of light sources and color, self-defined light-source angle, highly, the angle of divergence, light intensity, color effects be better.Digital camera directly is connected with computing machine, whenever takes just its shooting effect as can be seen of a photo, as facial expression not to or effect bad, it can be deleted, and retake then and there.In the present embodiment, the resolution that photo image is of a size of the 2.3cm*3cm photo image is that 300dpi image compression form is JPEG, and file size is of a size of 288 pixel *, 519 pixels, 1 gray level less than 10k byte finger print image.This digital camera taking module also can directly cut after photo is transmitted the cutter computing machine, can freely adjust size, the position of trim box, and preview simultaneously cuts effect.This time Kodak's special digital camera that adopts possesses state-of-the-art IEEE1394 interface, and transfer rate is 100,000,000, fast tens times than USB interface.
This acquisition system also comprises an image compression module, is used to compress the photo that this digital camera is taken.This image compression module judges earlier whether the photographic quality of digital camera shooting meets contractive condition, and the photo that will meet contractive condition is compressed to less than 10k, and compression algorithm is the ZIB algorithm.Photo is also encrypted with cryptographic algorithm it after overcompression is handled.
This acquisition system also comprises a finger print acquisition module, directly is connected with the living body finger print identifier, obtains the digital information of vital fingerprint image from the living body finger print identifier, and passes through the characteristic of system software Automatic Extraction fingerprint image.The characteristic of fingerprint image is stored in it in database of system by this information storage module after compression.Consider the compression algorithm that may use other, this finger print acquisition module is also preserved the raw digitized information of vital fingerprint image, has been equipped with the usefulness in future.
This acquisition subsystem also comprises a fingerprint comparison module, certain finger print information of scanner collection is compared, and extract finger print information the best in quality.
This data administration subsystem comprises information storage module, information inquiry module and statistics of database module.Wherein, information storage module is used for the information stores that will the collect database to this system; The information inquiry module is used for inquiring about the record of described database; And the statistics of database module is used for the record of database is added up.
