Processing module, after the image received is normalized image processing module, utilizes the eyes positioning side of Gabor transformation
Method display waveform figure, after the horizontal line of long range occurs in oscillogram, camera is believed to voice message, module output phonetic warning
Breath；The voice cue module for receiving phonetic warning information sends phonetic warning driver.
Explanation：When image processing module carries out Treatment Analysis, Eye Recognition is employed, principle is：In image
Pointwise translates each location point in reference template image, traversal search area in the field of search, while being surveyed according to some similitude
Principle is spent, the image-region and the correlation of reference template of the location point in the field of search are calculated, then according to the size of correlation
To judge the position of trace point.
Eye locating method based on Gabor transformation:Handled carrying out normalization to image to reduce the base of illumination effect
On plinth, using amplitude of the image after Gabor transformation at eyes it is larger the characteristics of, the seat of eyes is obtained by projecting method
Mark.
The beneficial effect of base case is：Control system is set, and camera is gathered after the facial expression of driver in real time, schemed
As processing module progress judges and output signal that the voice cue module for receiving signal then sends voice, driver is warned
Show, remind driver's careful driving, to avoid the occurrence of traffic accident, so as to ensure the life safety of human pilot.
Preferred scheme one：Based on scheme it is preferred, the main casing is connected to the bottom by spherical cradle head
On seat.Beneficial effect：Main casing is connected on base using spherical cradle head, to realize main casing in spherical cradle head
On rotate at any angle, to capture the facial expression of driver on operator seat, convenient use.
Preferred scheme two：Preferably one it is preferred, voice cue module include buzzer.Beneficial effect：Using
High-power buzzer, in hour of danger, driver is reminded in big decibel alarm.
Preferred scheme three：Preferably two it is preferred, shell body is provided with infra-red radiant illumination module.Beneficial effect
Really：Infra-red radiant illumination module is set, camera is illuminated using infrared illumination module, is illuminated, to enter
Row image recognition.
Preferred scheme four：Preferably three it is preferred, be additionally provided with what is be connected with image processing module in control system
Acceleration transducer.Beneficial effect：Connect acceleration transducer, the transport condition for judging vehicle, to carry out system
Power consumption control and control errors, so as to ensure the traffic safety of driver.
Preferred scheme five：Preferably four it is preferred, be additionally provided with what is be connected with image processing module in control system
Loudspeaker.Beneficial effect：Setting loudspeaker is used to realize interactive voice, easy to use.
