The following describes the technical scheme of the present invention in detail with reference to fig. 1.
The server acquires first basic information of each classroom and second basic information of a teacher; the first basic information comprises a classroom ID and a classroom area, and the second basic information comprises a teacher ID, a classroom ID and a course ID; and correlating the classroom ID, the classroom area, the teacher ID and the course ID to obtain a correlation information table.
The light control method is applied to classrooms for illustration, and the server can be a server of a school educational administration system and has the highest management authority. The server stores basic information of classrooms and basic information of teachers. The classroom ID may be related to a floor where the classroom is located, for example, a floor 1, floor 5, and floor 502 classroom, the classroom ID may be 0105502, the teacher ID may be any combination of the name and number of the teacher, and the number may be numbered according to the time of entering the teacher, or may be numbered according to the college or the subject of the professor to which the teacher belongs, which is not limited in this application.

Specifically, the control terminal can calculate the density of the students, and when the control terminal does not acquire the control right of the lamplight, the server can also calculate the density of the students. Now, taking the control authority of the control terminal to obtain the light as an example, how to calculate the density of students is described.
After receiving the light authority authorization message, the control terminal starts the camera, and the camera in the teaching environment collects video images in the visual angle range and sends the video images to the control terminal; the control terminal performs graying treatment on the video image to generate a gray video image; the control terminal performs image extraction operation on the gray video image according to a preset time interval to generate a video image; the control terminal performs feature recognition processing according to the video image, and counts the image boundary area subjected to the feature recognition processing to generate the information of the number of people; the control terminal determines the density grade according to the classroom area; and the control terminal determines the student density according to the density grade and the information of the number of people.
Specifically, still arrange the camera in the classroom to the picture that the camera is to the angle of view within range carries out video recording, can acquire the video image in classroom. After the control terminal receives the light authority authorization message, the camera is started, so that the adjustment of light is required for each lesson, the camera can be started while the light is adjusted, and the camera can perform subsequent collection work, including but not limited to collection of classroom teaching video and audio data and classroom listening video and audio data.
The video image of the camera can be sent to the control terminal through the control gateway, the control terminal processes the video image, the control terminal carries out weighting processing on three components in the color video image according to different weights, and each pixel point generates a first gray value according to the three components. And the control terminal calculates the average value of the first gray values of all the pixel points to obtain a gray threshold value. Comparing the first gray value of each pixel point with a gray threshold value, determining a second gray value of the pixel point after gray processing, and outputting gray image data according to the second gray value.
In a specific embodiment, the control terminal assigns different weights of 0.3, 0.6 and 0.1 to three Color channels Red (Red, R), green (Green, G) and Blue (Blue, B) in RGB Color Mode (RGB Color Mode) of the Color video, respectively. For example, one pixel point is R: 240. g: 223. b:204. after the graying treatment, the first gray value of the pixel point is r=g=b=240×0.3+223×0.6+204×0.1=226.2, and the like to obtain the first gray value of each pixel point. For example, "226.2, 130, 100, 50, 10" are all the first gray values, respectively, and the gray threshold is the average value 103.24 of the first gray values of all the pixels. And comparing the first gray level value of all the pixel points with a gray level threshold 103.24, wherein the pixel points with the first gray level value smaller than the gray level threshold output a second gray level value of 0, and the pixel points with the first gray level value larger than the gray level threshold output a second gray level value of 255.
And the control terminal performs image extraction operation on the gray image data according to a preset time interval to generate first image data. In a specific embodiment, the control terminal extracts the gray image data every 5 minutes to generate a first image data. The control terminal performs feature recognition processing according to the first image data, and counts the image boundary area subjected to the feature recognition processing to generate the information of the number of people.
In a specific embodiment, the control terminal identifies a plurality of first video image entry features, such as shoulder and neck features or facial features in an identification image, determines a target area according to the identification result, and counts the number of areas in which the shoulder and neck features or facial features are identified to generate the number of people information.

After the density level is calculated, the density of students can be determined, for example, the number of people information is 40, the number of people without duty is 5, the number of people without duty can be obtained according to preset course information, the classroom area is 63 square meters, the number of people corresponding to the classroom area is 45, and the density of students corresponding to the number of people 40 is 40/45=0.89 under the condition that the classroom area is unchanged.
Specifically, the control terminal is provided with mode selection information, and the mode selection information can be displayed in a button mode, for example, a manual control mode corresponds to a manual button, and an automatic control mode corresponds to an automatic button.
Accordingly, when the manual control mode is selected, the illumination may be manually increased or decreased. The increasing or decreasing value may be performed according to a preset illumination, for example, increasing or decreasing 10Lux per pressing of the increasing button or the decreasing button on the manual button.
Specifically, the current natural illuminance and the current illuminance of the light are measured by illuminance sensors, for example, the light is turned off, so that the natural illuminance is measured.
The current illumination of the classroom is determined according to the sum of the current natural illumination and the current lamplight illumination, and the preset illumination of the classroom is a tested value and can be set in advance according to experience.
The classroom should have illumination in real time, which is equal to the product of student density and preset classroom should illumination. For example, if the preset classroom illumination is 300Lux and the student density is 0.89, the real-time classroom illumination is 300 x 0.89=267 Lux.
The light compensation illumination is the difference value between the real-time due illumination of the classroom and the current illumination of the classroom. When the current illumination of the classroom cannot reach the real-time due illumination of the classroom, the current illumination of the classroom should be improved, and when the current illumination of the classroom exceeds the real-time due illumination of the classroom, the current illumination of the classroom is reduced.
The control gateway sends the lamplight adjusting coefficient to the corresponding driver according to the lamplight source ID;
and the driver drives the lamp light sources according to the lamp light adjusting coefficient so as to make the lamp light sources perform lamp light compensation.
Specifically, each control gateway in the teaching room corresponds to a light source, and the control gateway drives the light source through a driver. The light adjusting coefficient can directly adjust the illumination of one light source and can also distribute the illumination to a plurality of light sources, so that the plurality of light sources are controlled to realize the adjustment of light.
When the control of a plurality of lights is carried out, the light adjusting coefficient of each light source can be determined according to the number of the light sources, so that the control system sends the adjusting coefficient of each light source to the driver through the control gateway to increase or decrease the light illuminance through the driver.
