Method, system and air conditioner for air conditioner control based on facial features

Abstract

The invention relates to a method, a system and an air conditioner for controlling an air conditioner based on facial features. The method includes: receiving a picture with a face, performing facial feature analysis on the picture, and obtaining facial feature parameters; calculating the facial fat and thin degree FFR according to the facial feature parameters; The degree of fatness and thinness FFR calculates the degree of fear of heat L; according to the degree of fear of heat L, a control instruction for adjusting the operating parameters of the air conditioner is generated. The present invention uses a common face picture to analyze the user's air conditioner temperature preference in real time. Compared with the prior art, it does not need to establish a face database in advance to identify the user's identity, and does not need to analyze multiple pictures to generate activity judgment. It does not need to use a special temperature-sensing camera, and the ordinary lens of an ordinary smartphone can be used to detect heat and cold preferences. It is significantly superior to existing technologies in terms of product development costs, user privacy, hardware calculations, and application scenarios.

Description

technical field [0001] The present invention relates to the field of air conditioner control, in particular to a method, system and air conditioner for air conditioner control based on facial features. Background technique [0002] There are already some methods on the market that can intelligently control the operation of air conditioners. Some methods match the extracted face images with the images stored in the air conditioner storage module, and adjust the air conditioner operating parameters according to the matching results. Although this method can control the operation of the air conditioner through face recognition, it needs to establish a face database and air conditioner in advance. The corresponding relationship between parameters to obtain the user's air-conditioning preference. This method requires more preparation work in the early stage, which is not conducive to realization; there are also some methods that detect the position and size of the face, and then ...

Some methods match the extracted face image with the image stored in the air conditioner storage module, and adjust the operating parameters of the air conditioner according to the matching results. Although this method can control the operation of the air conditioner through face recognition, it needs to establish a face database and air conditioner in advance. The corresponding relationship between parameters to obtain the user's air-conditioning preference. This method requires more preparation work in the early stage, which is not conducive to realization; there are also some methods that detect the position and size of the face, and then calculate the movement of the indoor person. The amount of movement calculates the amount of human activity, and air conditioning is controlled according to the amount of activity. This method needs to capture a large number of continuous pictures for analysis, and the amount of calculation is very large; Video or pictures control the operation of the air conditioner, this method needs to increase the cost of the product
