And 104, adjusting the light transmittance of the electrochromic glass according to the current output value.

The electrochromic glass can realize the purpose of regulating the illumination by utilizing the adjustability of the light transmission (or absorption) performance of the electrochromic material under the action of an electric field. The electrochromic system can keep the interior of the vehicle cool in summer and warm in winter by selectively absorbing or reflecting external heat radiation and preventing internal heat from being diffused.

The light transmittance of the electrochromic glass is adjusted based on the current output value, and the current output value is obtained based on the eye image of the target object, so that the aim of automatically and intelligently adjusting the light transmittance of the electrochromic glass based on the eye image of the target object can be fulfilled.

After the training is finished, obtaining the weight parameter of the neural network model, namely obtaining the second weight parameterThe network model, the second network model, may be used for online prediction.

The second network model obtains a plurality of parameter values based on the deviation values of the intermediate current output value and the feedback current value, the feedback current value is the current output value obtained at the last moment, and the intermediate current output value is the current output value obtained at the current moment based on the eye stimulation degree value.

The plurality of parameter values can comprise three parameter values which are respectively a proportional parameter value, an integral parameter value and a differential parameter value, and the three parameter values are input into the PID controller to obtain a current output value so as to adjust the electrochromic glass. The PID controller adopts a plurality of parameter values as input, outputs a current output value, and the current output value is used as a control quantity to control the color of the electrochromic glass, so that the intelligent adjustment of the electrochromic glass along with the stimulation of human eyes can be realized.

taking the updated Nth eye stimulation degree value as the eye stimulation degree value of the target object.

In this embodiment, when the eye image of the target object is obtained, one eye image may be obtained at intervals of a preset time to determine the eye stimulation level value of the target object, or a plurality of eye images may be obtained within a preset time period, for example, 25 eye images may be obtained in one minute. In the case of acquiring a plurality of eye images, in order to avoid the flicker effect of the electrochromic glass caused by the jitter of the obtained eye stimulation degree values, the smoothing can be performed by adopting a low-pass filtering mode. Namely, for a first eye image and a second eye image acquired at adjacent time, a first eye stimulation degree value and a second eye stimulation degree value are acquired, and then the second eye stimulation degree value is updated by using the first eye stimulation degree value.

And updating the eye stimulation degree value of the eye image acquired at the adjacent moment by using low-pass filtering p _ cur' = e × p _ cur + (1-e) × p _ prev. Wherein e is a filter coefficient, the value range is 0 to 1, p _curis the eye stimulation degree value at the current moment; p _ prev is the eye stimulation level value at the last moment; p _ cur' is the updated eye stimulation level value at the current time.

And sequentially updating the eye stimulation level values except the first eye stimulation level value in the N eye stimulation level values. And updating the (i + 1) th eye stimulation degree value by using the (i) th eye stimulation degree value, wherein i is a positive integer less than N. For example, the second eye stimulation level value is updated with the first eye stimulation level value, and then the third eye stimulation level value is updated with the second eye stimulation level value (at this time, the second eye stimulation level value is updated), which are sequentially performed until the nth eye stimulation level value is updated. That is, the update of the nth eye stimulation level value depends on the N-1 eye stimulation level values that are arranged in front thereof. And then, taking the updated Nth eye stimulation degree value as the eye stimulation degree value of the target object, so as to smooth the obtained eye stimulation degree value when a plurality of eye images are obtained, avoid shaking, prevent the electrochromic glass from flickering and improve the adjusting effect of the electrochromic glass.
