S202, acquiring a sky image, inputting the sky image into a pre-trained illumination recognition model, and calculating illumination detection parameters, wherein the illumination detection parameters comprise sky brightness parameters and/or sunlight brightness parameters;

alternatively, the terminal may acquire an input of a sky image to calculate a corresponding dimming control signal, in addition to receiving some direct control information input.

After the terminal acquires the sky image, inputting the sky image into a pre-trained illumination recognition model, calculating the sky color and the sunlight color in the sky image through the illumination recognition model, and performing gray analysis on the sky image to calculate illumination detection parameters.

Specifically, the terminal first obtains a corresponding optical parameter table based on the selected basic mode, where the optical parameter table is pre-stored in the memory of the sky light control module. The optical parameter table respectively comprises color temperatures, color coordinates and brightness of the main illumination light source, the first side illumination light source and the second side illumination light source at different moments of different modes.

Specifically, the terminal may obtain a user-controlled brightness level preference, wherein the brightness level preference includes a high brightness preference, a medium brightness preference, and a low brightness preference. Further, a current natural illumination intensity and a current user density within the target space are detected by the sensor. For example, if the illumination light source is installed in the conference room, the current natural illumination brightness in the conference room and the current user density in the conference room, which is the number of users, are detected by the sensor. Further, in response to the network request instruction, the current natural time and weather data of the location of the target space are obtained. The current natural time and weather data of the meeting room location is obtained, for example, via a wireless network.

S204, calculating a dimming control signal according to the simulated lighting algorithm based on the multi-mode information and/or the illumination detection parameters;

The illumination detection parameters and the multi-mode information can be combined to calculate the dimming control signal to realize sky illumination.

Further, the illumination correction factor may be calculated and determined according to a weighted formula. The weighting formula is:

C＝C1+C2+C3

wherein, C is the illumination correction factor, C1 is the weighted average parameter of the control information, C2 is the weighted average parameter of the current natural illumination brightness and the current user density, and C3 is the weighted average parameter of the weather data. For example, if the basic mode selected by the user is a rhythmic mode, if the environment tendency with the preference of the middle brightness is selected in the user control information, C1 is set to 0.33, if the natural illumination brightness is low in the current environment, the number of people in the space is large, C2 is set to 0.50, and if the current weather requested by the network is sunny, the corresponding C3 is set to 0.54; the illumination correction factor C may be calculated as 1.37. If the current natural time is 14 pm, the brightness value of the main illumination light source is 700×1.37=959lm; the luminance values of the first side illumination light source and the second side illumination light source are 100x1.37=137 lm. And obtaining the color coordinates and brightness values corresponding to the corrected main illumination light source, the first side illumination light source and the second side illumination light source under the CIE1976 system. And outputting a dimming control signal according to the color temperature, the color coordinates and the corrected brightness parameters in the table for the main illumination light source to correspondingly control the main illumination light source.

For the first side illumination source and the second side illumination source, the color space of CIE1976 can be converted and calculated through a formula to obtain the corresponding RGB brightness value, and the first side illumination source and the second side illumination source can be correspondingly controlled according to the converted RGB brightness value and the output dimming control signals such as the sky color coordinates, the colors and the like in the table. Specifically, the method for calculating the RGB brightness value is to convert the first color coordinate into a tristimulus value according to a target formula, perform matrix operation on the tristimulus value, and determine the first RGB value; wherein, the target formula is:

Y＝Y；

cx, cy is the first color coordinate;

wherein, the matrix operation is:

R＝3.2406X-1.5372Y-0.4986Z

B＝0.0557X-0.2040Y+1.0570Z
