Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Control method, device and the car plate of Car license recognition instrument proposed according to embodiments of the present invention is described with reference to the accompanying drawings
Identifier describes the control method of the Car license recognition instrument proposed according to embodiments of the present invention with reference to the accompanying drawings first.
Fig. 1 is the flow chart of the control method of the Car license recognition instrument of one embodiment of the invention.
As shown in Figure 1, the control method of the Car license recognition instrument includes the following steps：
In step S101, intensity of illumination is acquired.
Wherein, in one embodiment of the invention, acquisition intensity of illumination further comprises：It is adopted according to prefixed time interval
Collect the brightness information of preset times Car license recognition instrument local environment；It is averaged that be worth to illumination strong according to preset times brightness information
Degree.
Optionally, in one embodiment of the invention, prefixed time interval is 5 seconds, and preset times are 12 times.
For example, starting the luminance signal of output maximum brightness value first to MCU (Microcontroller Unit, micro-control
Unit processed), and while starting open light compensating lamp；Secondly at interval of the brightness information of detection in about 5 seconds, nearest 12 times of caching
The brightness information of detection.
In step s 102, judge intensity of illumination whether less than threshold value of turning on light.
In step s 103, if it is, output is turned on light, signal and further judges light to the light compensating lamp of Car license recognition instrument
According to intensity whether higher than threshold value of turning off the light, wherein threshold value of turning off the light is more than threshold value of turning on light.
In step S104, if it is, output turns off the light signal to light compensating lamp.
It should be noted that turn on light threshold value and threshold value of turning off the light can be configured according to actual conditions, do not make herein specific
Limitation.
That is, processing brightness information, such as takes 12 detection average brightness, should currently be turned on light also according to value judgement
It is to turn off the light, if brightness is less than some given threshold, exports order of turning on light and turn on light to MCU；If some setting of the high space of brightness
Threshold value then exports order of turning off the light and turns off the light to MCU.Note that light lamp luminance threshold and luminance threshold of turning on light are not the same values, turn on light
Value should be less than value of turning off the light, and centre can have a return difference.
Further, incoming if there is ordering, it detects whether to enter manual mode order, if it is, turning off the light into empty
Not busy pattern, is not specifically limited herein.
Wherein, in one embodiment of the invention, wherein the signal if output is turned off the light, video capture is controllable to be mended
The opening and closing of light lamp；The signal if output is turned on light, light compensating lamp are kept it turned on.
That is, when signal is turned off the light in output, video capture can normal control light compensating lamp on and off, light at this time
Degree can be setting value or MCU default values.
In addition, when signal is turned on light in output, video capture output is invalid, because what lamp originally open, and because
Signal of turning on light is outputed, so video capture does not close light compensating lamp yet, ensures camera shooting effect.
Further, in one embodiment of the invention, after signal to light compensating lamp is turned on light in output, further include：Root
The object brightness of light compensating lamp is obtained according to intensity of illumination；Light compensating lamp light filling is controlled according to object brightness.
In other words, brightness information is handled, 12 detection average brightness is such as taken, corresponding brightness rank is converted to according to value, is passed
Parameter sets light compensating lamp brightness to MCU.
In an embodiment of the present invention, it is acquired by photosensitive sensor, is equivalent to a semiautomatic control pattern.Behaviour
Work person can set the brightness of light compensating lamp, can also can be automatically arranged with manual setting later, and the switching signal of light compensating lamp,
It can be controlled and be exported by photosensitive circuit completely.
Under photosensitive sensor automatic control mode, video capture output can have the following effects：
1) when photosensitive circuit output turn off the light signal when, video capture can normal control light compensating lamp on and off, can be by bright
The steady state value for spending operating software setting determines；
2) when signal is turned on light in photosensitive circuit output, video capture output is invalid, because what lamp originally open, and
Because photosensitive circuit outputs ON signal, to which video capture can not close light compensating lamp.
