Description of the drawings
The theory diagram for preventing fatigue system based on iris recognition that Fig. 1 is provided for the utility model.
Specific embodiment
With reference to the accompanying drawings and examples the utility model is described in detail.
Fatigue system prevented based on iris recognition as shown in figure 1, a kind of, including iris recognition module, control module, language
Sound prompting module, alarm modules and mode of operation handover module：
The iris recognition module is used for Real-time Collection, process, storage iris feature information and calculates iris feature letter
The registration of breath, and registration is sent to into control module；
The control module judges fatigue state for according to the size of registration and duration, and according to tired shape
State controls the voice reminder module, alarm module and mode of operation handover module；
The voice reminder module is used for receiving the instruction of control module, starts voice prompting function；
The alarm modules are used for receiving the instruction of control module, start alarm function；
The mode of operation handover module is used for receiving the instruction of control module, switching working mode.
The iris image of different area includes the iris feature information of varying number, people in fatigue or doze state,
Due to eyelid and eyelashes covering part or whole irises, so as to affect integrity degree and the iris feature information of iris image acquiring
The registration of timing.
This prevents fatigue system from utilizing iris recognition technology, calculates the coincidence of the iris feature information for collecting every time
Whether degree, judge user in fatigue state according to the size of registration and duration, and according to its degree of fatigue, startup
Voice prompting function, alarm function and switching working mode.
It is of the present utility model to prevent fatigue system to be applied to the terminals such as mobile phone, computer, flat board and automobile.
Wherein, voice reminder module can be the voice device being separately provided, it is also possible to by mobile phone, computer, flat board and
The loudspeaker of the terminals such as automobile realize voice prompting function；The alarm modules can be the alarm device being separately provided, it is also possible to
Alarm function is realized by the loudspeaker of the terminals such as mobile phone, computer, flat board and automobile, wherein, if terminal is automobile, be can be combined with
The flash lamp of automobile, trouble light etc. remind nearby vehicle and pedestrian to note；Mode of operation handover module can by mobile phone, computer,
The mode of operation of flat board etc. is switched to shutdown/holding state, or the mode of operation of automobile is switched to automatic Pilot state.
Wherein, the iris recognition module includes iris capturing unit, iris processing unit, iris memory cell and coincidence
Degree computing unit：
The iris capturing unit is used for gathering iris image；
The iris processing unit pre-processed for the iris image to collecting and characteristic information extraction；
The iris memory cell is used for storing the first iris feature information collected during the system starts；
The registration computing unit was collected for the first time by the iris feature for collecting every time information with storage
Iris feature information contrasted, calculate the registration of the iris feature information for collecting each time, and registration passed
It is sent to control module.
Wherein, the control module is provided with the higher limit and lower limit of iris feature information registration, if collect
The registration of iris feature information is more than higher limit, then be normal condition；If at the registration of the iris feature information for collecting
In higher limit and lower limit, then it is slight fatigue state；If the registration of the iris feature information for collecting is less than lower limit,
It is then severe fatigue state.
Higher limit and lower limit can arrange different threshold values according to different terminals, with safety requirements vapour the most harsh
As a example by car terminal, the higher limit of its registration is set to 50%, lower limit and is set to 30%, if registration is between 30% and 50%,
User is in slight fatigue state；If registration is less than 30%, user is in major fatigue state.It is mobile phone, computer, flat
The higher limit and lower limit of the terminals such as plate suitably can be relaxed.
If the registration of the iris feature information for collecting continuously is in higher limit and lower limit several times, the control
Molding block sends instruction to the voice reminder module, starts voice prompting function；If the weight of the iris feature information for collecting
Right to be continuously less than lower limit several times, then the control module sends finger to the alarm modules and mode of operation handover module
Order, starts alarm function and switching working mode.
In view of under non-fatigue state, the blink of people, narrow the eye motions such as eye and also influence whether iris feature information
Registration, for avoiding system erroneous judgement, needs the number of times continuously occurred according to threshold values, long so as to draw fatigue state duration
It is short, judge whether accordingly to start corresponding function.By taking safety requirements car terminals the most harsh as an example, if the registration is continuous
It is between 30% and 50% for 3 times, then the control module sends instruction to the voice reminder module, starts voice reminder work(
Energy；If registration is less than 30% continuous 3 times, the control module is sent to the alarm modules and mode of operation handover module
Instruction, starts alarm function and is switched to automatic Pilot state.The terminals such as mobile phone, computer, flat board are starting the same of alarm function
When, mode of operation is switched to into standby/off-mode also.
The iris capturing unit is a camera with infrared induction, and the iris capturing unit is at interval of certain
Time gather an iris image, it is preferable that the iris capturing unit every 1 second gather an iris image.
It is as the further optimization of the technical program, described to prevent fatigue system that also there is iris startup function, by terminal
The iris feature information of owner is stored in advance in the iris memory cell, and then terminal owner passes through iris recognition mould
After block successfully recognizes iris feature information, the control module sends instruction to mode of operation handover module, switches the terminal into
Starting state.
Embodiment described above only expresses embodiment of the present utility model, and its description is more concrete and detailed, but and
Therefore the restriction to the utility model the scope of the claims can not be interpreted as, as long as the institute in the form of equivalent or equivalent transformation
The technical scheme of acquisition, all should fall within protection domain of the present utility model.
