Detailed Description
The embodiment of the application provides a power consumption control method and electronic equipment, which are used for solving the technical problem that the power consumption of an iris recognition system is too high in the prior art and achieving the technical effect of reducing the power consumption of the iris recognition system. In order to solve the technical problems, the general idea of the embodiment of the present application is as follows:
controlling the iris recognition system to emit first infrared light at a first preset power consumption;
receiving second infrared light generated based on reflection of the first infrared light;
determining a value of a first parameter corresponding to the second infrared light;
adjusting the first preset power consumption of the iris recognition system based on the value of the first parameter.
According to the technical scheme in the embodiment of the application, the technical means that the iris recognition system is controlled to emit infrared light with first preset power consumption and then the power consumption of the iris recognition system is adjusted on the basis of the first preset power consumption is adopted. The technical effect of reducing the power consumption of the iris recognition system is achieved.
The main implementation principle, the specific implementation mode and the corresponding beneficial effects of the technical scheme of the embodiment of the present application are explained in detail with reference to the accompanying drawings.
Example one
The human eye structure is composed of parts such as the sclera, iris, pupil lens, retina, etc. The iris is an annular segment between the black pupil and the white sclera containing many details characteristic of interlaced spots, filaments, coronaries, stripes, crypts, etc. And the iris will remain unchanged throughout life span after it is formed during the fetal development stage. These features determine the uniqueness of the iris features and also the uniqueness of the identification. Therefore, the iris feature of the eye can be used as an identification target for each person. Among all biometric techniques, including fingerprints, iris recognition is currently the most convenient and accurate one to apply.
In the iris recognition system, when the iris recognition system emits infrared light to irradiate an object to be recognized, the infrared light reaches the object to be recognized and is reflected. The iris recognition system receives the infrared light reflected by the object to be recognized, generates an image of the object to be recognized, and extracts, compares and judges the acquired iris image. The higher the power consumption of the iris recognition system is, the higher the intensity of the emitted infrared light is, the stronger the intensity of the infrared light reflected by the object to be recognized is received, and the higher the definition of the generated image is. Because the iris recognition systems need different image definitions in different working modes, the power consumption of the iris recognition systems is different, but in the prior art, the iris recognition systems all emit infrared light with the same power consumption.
When the above problem is encountered, the power consumption control method provided in the first embodiment of the present application can be adopted, please refer to fig. 1, which includes:
s101: controlling the iris recognition system to emit first infrared light at a first preset power consumption;
s102: receiving second infrared light generated based on reflection of the first infrared light;
s103: determining a value of a first parameter corresponding to the second infrared light;
in the embodiment of the application, after first infrared light sent by an iris recognition system with first preset power consumption reaches an object to be recognized, second infrared light is formed through reflection of the object to be recognized, and after the iris recognition system receives the second infrared light reflected by the object to be recognized, a value of a first parameter corresponding to the second infrared light is determined, wherein the value of the first parameter comprises the intensity of the second infrared light received by the iris recognition system or the definition of a first image generated by the second infrared light.
Optionally, before controlling the iris recognition system to emit the first infrared light with the first preset power consumption, the method further includes:
determining the current working mode of the iris recognition system as a first working mode;
determining the first preset power consumption based on the first working mode.
In the embodiment of the present application, the working mode of the iris recognition system is firstly confirmed, which can be divided into four types: a detection working mode, a positioning working mode, an eye tracking working mode and an iris recognition working mode.
In the detection working mode, the iris recognition system is used for recognizing the face of the object to be recognized, so that the face is only required to be recognized from the shot image in the detection working mode; in the positioning working mode, the iris recognition system is used for recognizing eyeballs of an object to be recognized, namely the position of the eyeballs of the object to be recognized needs to be positioned after the face of the object to be recognized is recognized, and the image needing to be shot is clearer than the image in the detection mode; in the eye tracking working mode, the iris recognition system is used for tracking the rotation direction of the eyeballs of the object to be recognized, so that the eyeballs of the object to be recognized need to be recognized, the rotation direction of the eyeballs needs to be recognized, and the definition of the required picture is higher than that in the positioning working mode; in the iris recognition working mode, the iris recognition system is used for recognizing the iris of the object to be recognized, at the moment, the iris image of the eyeball of the object to be recognized needs to be shot, and the special point in the iris of the object to be recognized is recognized, so that the required image definition is higher at the moment.
Because the stronger the intensity of the infrared light reflected back to the iris recognition system is, the clearer the photographed image is, the first preset power consumption of the detection working mode is less than the first preset power consumption of the positioning working mode, the first preset power consumption of the positioning working mode is less than the first preset power consumption of the eye tracking working mode, and the first preset power consumption of the eye tracking working mode is less than the first preset power consumption of the iris recognition working mode.
In the embodiment of the application, because the power consumptions required by the iris recognition system in different working modes are different, the power consumptions required in different working modes are counted through repeated tests to obtain first preset power consumptions in different working modes, after the current working mode of the iris recognition system is detected, the power consumption of the iris recognition system is set to be the first preset power consumption corresponding to the current first working mode, and the infrared light is emitted with the first preset power consumption.
In a specific implementation process, specifically, in the detection working mode, the iris recognition system needs to emit infrared light with power consumption of 0.1W, in the positioning working mode, the infrared light needs to emit infrared light with power consumption of 0.5W, in the eye tracking working mode, the infrared light needs to emit infrared light with power consumption of 1W, and in the iris recognition working mode, the infrared light needs to emit infrared light with power consumption of 1.5W. At this time, if it is detected that the iris recognition system is in the eye tracking operation mode, power consumption of the iris recognition system is set to 1W, and the first infrared light is emitted with a first preset power consumption of 1W.
S104: adjusting the first preset power consumption of the iris recognition system based on the value of the first parameter.
Adjusting the first preset power consumption of the iris recognition system based on the value of the first parameter specifically includes:
when the value of the first parameter is larger than a first preset threshold value corresponding to the first working mode, reducing the power consumption of the infrared searchlight from the first preset power consumption to first power consumption; and when the value of the first parameter is smaller than the first preset threshold value, increasing the power consumption of the infrared searchlight from the first preset power consumption to a second power consumption.
In the embodiment of the application, when the value of the first parameter is the intensity of the second infrared light, the intensity of the received second infrared light is compared with the size of a first preset threshold, the first preset threshold is the threshold of the infrared light intensity corresponding to the first working mode of the iris recognition system, and when the intensity of the received second infrared light is within the first preset threshold, the definition of a first image generated based on the second infrared light just can meet the required image definition in the first working mode. When the intensity of the received infrared light is greater than a first preset threshold value, it is indicated that the definition of an image generated by the second infrared light is greater than the required image definition in the first working mode, and the current power consumption of the infrared searchlight is reduced until the intensity of the second infrared light is within the first preset threshold value; when the intensity of the received infrared light is smaller than a first preset threshold value, it is indicated that the definition of an image generated by the second infrared light is smaller than the image definition required in the first working mode, and the object to be identified cannot be identified, the current power consumption of the infrared searchlight is increased until the intensity of the second infrared light is within the first preset threshold value
When the value of the first parameter is the definition of the first image, comparing the definition of the first image with a first preset threshold value, wherein the first preset threshold value is a threshold value of the image definition corresponding to the first working mode of the iris recognition system, and when the definition of the first image generated based on the second infrared light is within the first preset threshold value, the required image definition in the first working mode is just met. When the definition of the first image is larger than a first preset threshold, the definition of the first image is larger than the image definition required in the first working mode, and the current power consumption of the infrared searchlight is reduced until the definition of the first image is within a third preset threshold; when the definition of the first image is smaller than a first preset threshold, it is indicated that the definition of the first image is smaller than the image definition required in the first working mode, the generated first image definition is smaller, and the object to be recognized cannot be recognized, the current power consumption of the infrared searchlight is increased until the definition of the first image is within the first preset threshold.
