Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, provide an intelligent lighting adjustment system based on facial expression model recognition and its method, solve the problems of the existing automation control system program and center on equipment, and be able to automatically shoot and identify users The facial image can judge the user's expression according to the changes of facial features and automatically send out a light control signal, so that the color and intensity of the light can be changed according to the user's emotions, achieving a high degree of humanization and intelligence

Embodiment 1

[0127] The first step is to establish an expression model database. First, establish an expression model database with expression model data of calm expressions, happy expressions (taking smiles as an example), sad expressions, and angry expressions.

[0128] The emoticon model library must be specific to the user. A photo of 4 expressions of a specific person is required. Using the same user as the previous one, you need to take pictures of happy expressions, sad expressions and anger, such as Figure 7 , Figure 8 , Picture 9 Shown. Then according to the above steps, the four kinds of expression data are processed in sequence, and the process of processing the expression model data is the same as that of image processing during expression recognition. After the model data is standardized, the distance information between the corresponding points shown in Table 1 is calculated and stored in the expression model library. At this time, there are 4 expression models in the expre...

Embodiment 2

[0141] Still selecting the same person, the model library uses the model library built in Example 1, and another picture is used for testing, such as Picture 11 As shown, the following settlement data are available:

[0142] Test the similarity value of facial features of face and calm expression: Left eyebrow: R lb =8.23%; right eyebrow: R rb = 4.84%; left eye: R le = 81.17%; right eye: R re = 70.46%; mouth: R m =8.24%; the comprehensive similarity between the test face and the calm expression calculated by formula (15): R=37.22%

[0143] Test the similarity value of the facial features of the face and the happy expression: Left eyebrow: R lb =9.12%; right eyebrow: R rb = 20.65%; left eye: R le = 63.05%; right eye: R re =77.5%; mouth: R m =6.46%; the comprehensive similarity between the test face and the calm expression calculated by formula (15): R=38.25%

[0144] Test the similarity value of facial features of human face and sad expression: Left eyebrow: R lb = 28.16%; right eyebr...

Abstract

The invention relates to a light intelligent adjusting system and method based on expression model identification. A technical characteristic is that the light intelligent adjusting system is formed by an image acquisition and light control device and an expression identification device which are connected; the internal circuit of the image acquisition and light control device comprises a power module, an image acquisition module, a single-chip microcomputer, a transmission module, a light driving module, various color lamps, a horizontal rotating motor, and a vertical rotating motor; the method comprises that the image acquisition and light control device acquires a human face image and sends the human face image to the expression identification device and that the expression identification device analyzes the expression in the human face image and sends a light control signal to a control device in order that the control device switches on different color lamps. The system and the method may determine the expression of a user according to a change of the five sense organs of a human face and automatically gives the light control signal so that the color and the intensity of the light may vary with the emotion of the user, thereby achieving a user-friendly light intelligent control function and adjusting the mood of the user.

Description

Technical field [0001] The invention belongs to the technical field of pattern recognition, and in particular relates to a light intelligent adjustment system and method based on expression model recognition. Background technique [0002] Traditional lighting control systems mainly include manual control and time control. Its advantages are simple, effective, and intuitive, but rely too much on the controller, the control is relatively scattered, it is difficult to achieve centralized management, and the real-time and intelligent degree is too low. With the rapid development of information technology and the continuous progress of society, smart homes have begun to enter people's lives. Intelligent light control is one of the most used items in smart homes. People’s requirements for efficient lighting control and functional diversification are also increasing. In order to achieve the automatic adjustment of indoor lighting, beautify the environment, adjust the brightness of the ...
