Description
Technical field
The invention belongs to iris recognition technology field, in particular to a kind of application method of iris recognition technology.
Background technique
Iris recognition technology is to carry out identification based on the iris in eyes, is applied to security device (such as gate inhibition),
And have the place of highly confidential demand, still, present iris recognition technology in use, iris image acquiring camera all
It is fixed, but but to have height to have low for the raising of user, very big inconvenience is brought, for this purpose, the present invention proposes a kind of iris
The application method of identification technology.
Summary of the invention
Of the existing technology in order to solve the problems, such as, the present invention provides a kind of application methods of iris recognition technology, should
The application method design of iris recognition technology rationally, can select the position for opening camera according to the height of user, so as to
The quality that image is acquired when enough improving iris recognition, improves the quality of identification, and can judge according to the gait frequency of user
The state of user, to decide whether to open sound prompt function.
To achieve the goals above, the present invention is to realize by the following technical solutions: a kind of iris recognition technology
Application method, the application method of the iris recognition technology the following steps are included:
Step 1: Gait Recognition;Firstly, the iris image acquiring camera that installation height is different is used before iris recognition
Family starts Gait Recognition when entering Gait Recognition range, if recognition failures, is rejected for entry into, if identified successfully, extracts
Gait distance, gait frequency and user's height are spare out;
Step 2: state judgement;According to the distance of gait frequency and each step, the state that user is in is judged, if step
Greatly to a certain extent, and the distance of each step is usual compared with user when big certain numerical value then illustrates that user is in and catches up with state frequency
The state of emergency such as time or anxiety;
Step 3: camera is opened;It is opened according to the camera that the judgement of the height of user is opened if height is higher
The corresponding iris image acquiring camera in top opens the corresponding iris image acquiring camera in bottom if height is lower,
Judge whether voice prompting according to the state of user, if user is in normal state, carries out the relevant voice of iris recognition
Prompt, if user is in a state of emergency, cancels voice prompting, shortens the time of entire identification process, then carry out iris
Picture collection;
Step 4: iris recognition;Iris recognition is carried out after iris picture collection, if identified successfully, allow into
Enter, is rejected for entry into if recognition failures.
As a kind of preferred embodiment of the invention, the relevant voice prompting of iris recognition in the step 3 needs basis
Actual conditions setting, for example, eyes direct-view where, the information such as not close one's eyes.
As a kind of preferred embodiment of the invention, in the step 1 when carrying out Gait Recognition, first by monitoring camera
Machine acquires user's gait, obtains the video sequence of gait with tracking by detecting, the gait of user is extracted by Preprocessing
Feature carries out motion detection, motion segmentation, the pass of the Gait Recognitions such as feature extraction early periods to the gait motion in image sequence
Key processing, then, using being further processed, becomes the same mode that the gait of database is stored in oneself, finally,
Identification is compared with the gait feature in gait data library in freshly harvested gait feature.
As a kind of preferred embodiment of the invention, in the step 4 after carrying out iris recognition, if recognition failures energy
It is enough to carry out relevant processing as needed, for example sound an alarm or alarm.
Beneficial effects of the present invention:
1, the application method of this iris recognition technology can install the different iris of multiple height in application as needed
Image Acquisition camera can be taken the photograph before iris recognition according to the iris image acquiring that the height of user opens respective heights
As head, the quality of image is acquired when so as to improve iris recognition, improves the quality of identification.
2, the application method of this iris recognition technology combines Gait Recognition, on the one hand, can be improved safety, another party
Face, can provide judgment basis for the unlatching of iris image acquiring camera, also, Gait Recognition be close to during into
Capable, it will not influence the progress of iris recognition.
3, when the application method of this iris recognition technology is according to Gait Recognition user's gait frequency for extracting and gait away from
From, judge the state of user, thus decide whether to open sound prompt function, if gait frequency is greatly to a certain extent, and
The distance of each step big certain numerical value when usual compared with user then illustrates that user is in the state of emergency such as in a hurry or anxiety,
If user is in a state of emergency, cancel voice prompting, so as to shorten the time of entire identification process, practicability is high.
