And S40, when the multiplexing camera is detected to not recognize the target information within a preset time threshold, enabling the light central control system to close the light in the current classroom.
In the embodiment, when the multiplexing camera is detected to not recognize the target information within the preset time threshold, it can be determined that the teacher in the current classroom has completed the current teaching process, and at the moment, the light in the current classroom can be turned off through the light central control system, so that the waste of resources is reduced. It should be noted that, at this time, the multiplexing camera can start the video recording function, but can temporarily close the function of identifying the face brightness of the target user, the facial expression of the target user, the background color of the courseware and the display content of the courseware in the current class room, so as to reduce the workload of the multiplexing camera. In another embodiment, when the multiplexing camera does not recognize the target information within the preset time threshold, the light central control system irradiates the shooting area of the multiplexing camera in a soft light form, and simultaneously the terminal equipment plays light background music or/and video pictures until the multiplexing camera does not recognize the target information, and the light central control system turns off the light in the current classroom.
In an embodiment, the multiplexing camera integrates a color detection algorithm, a face recognition method and an image recognition algorithm;
the enabling the multiplexing camera to identify the face brightness of the target user, the facial expression of the target user, the background color of courseware and the display content of the courseware in the current class room in real time comprises the following steps:

Further, after receiving the courseware opening instruction sent by the control terminal in the current classroom, the method further comprises the following steps:
acquiring the illumination intensity in the current environment of the current classroom, which is detected in real time by a preset illumination intensity sensor, determining the initial brightness and the ending brightness of the courseware display picture in the current classroom through the illumination intensity, and adjusting the brightness of the courseware display picture according to the initial brightness and the ending brightness.
The initial brightness is the brightness of the initial time point of the courseware display picture under the illumination intensity in the current environment, and the ending brightness is the brightness of the ending time point of the courseware display picture under the illumination intensity in the current environment, wherein the brightness size of the ending brightness is larger than the brightness size of the initial brightness; after determining that the teacher has started the current teaching process, the embodiment can acquire the illumination intensity in the current environment through the preset illumination intensity sensor installed in the proper position in the current classroom, at this time, the embodiment can determine the brightness of the courseware display picture suitable for human eyes according to the current illumination intensity, wherein the brightness comprises initial brightness and ending brightness, and the embodiment adjusts the brightness from the initial brightness to the ending brightness, so that the embodiment can attract the attention of human eyes.
Further, the determining the target information by multiplexing the camera includes:
acquiring the character characteristics of the target user and the position information of the courseware display picture displayed in the current classroom, and calculating the actual distance between the target user and the courseware display picture in real time through the multiplexing camera according to the character characteristics and the position information;
when the actual distance is within a preset target distance, determining the target user and the courseware display picture as the target information;
and when the actual distance exceeds a preset target distance, prompting that the target information is missing, and continuously calculating the actual distance between the target user and the courseware display picture in real time through the multiplexing camera according to the character characteristics and the position information.
As can be appreciated, the present embodiment calculates the actual distance in real time based on the character features of the target user and the position information of the courseware display screen, and further determines the target information based on the actual distance.
Further, after the light central control system simultaneously adjusts the light irradiation angle, the light irradiation height and the light color temperature in the current classroom according to the first light information, the light central control system further includes:
when detecting that at least one of the face brightness of the target user, the facial expression of the target user, the background color of the courseware and the display content of the courseware is changed in real time, re-analyzing second lamplight information which is most suitable for the current class room according to the face brightness of the target user, the facial expression of the target user, the background color of the courseware and the display content of the courseware after the change, and transmitting the second lamplight information to a lamplight central control system in real time so that the lamplight central control system can simultaneously adjust the lamplight irradiation angle, the irradiation height and the lamplight color temperature in the current class room according to the second lamplight information.
Understandably, in this embodiment, the real-time detection is performed on the face brightness of the target user, the facial expression of the target user, the background color of the courseware and the display content of the courseware by using the multiplexing camera, and one of them is changed, so that the lighting angle, the lighting height and the lighting color temperature in the current classroom can be determined again.
Further, the detecting, in real time, that at least one of the target user face brightness, the target user facial expression, the courseware background color, and the courseware display content is changed includes:

and when the page change number in the courseware display picture is detected to be greater than or equal to a preset number threshold value in real time within the preset time, confirming that the courseware display content is changed in a non-light influence manner. Understandably, when a non-light influencing change occurs in the courseware presentation content, the change in the courseware presentation content is not taken into consideration for adjusting the light irradiation angle, irradiation height, and light color temperature in the current class room.
As can be appreciated, in this embodiment, in order to determine whether frequent page number changes occur in the courseware display content (to determine that the number of page changes is 1 in a preset period of time and is smaller than 2 set by the preset number threshold after comparing the number of page changes with the preset number threshold, for example, the number of page changes is 1 in 5 seconds, and then it is determined that light influence changes occur in the courseware display content), when frequent page number changes occur (that is, it is understood that the courseware display content changes), this embodiment does not add the courseware display content to consideration factors of light irradiation angle, irradiation height and light color temperature in the current courseware.

when the light effect is identical to the first light information, determining that the light effect is correct;
and when the light effect does not coincide with the first light information, enabling the light central control system to readjust the light effect which coincides with the first light information in the current classroom.
Understandably, this embodiment is mainly for verifying whether the light effect is consistent with the first light information, enhancing the supervision of the subsequent light effect, and avoiding affecting the experience effect of students and teachers.
Further, after the lighting central control system turns off the lighting in the current classroom, the lighting central control system further includes:
