Method and system for controlling air conditioner based on facial features and air conditioner

Abstract

The invention relates to a method and system for controlling an air conditioner based on facial features. The method comprises receiving an image containing a face, and analyzing facial features according to the image to obtain parameters of the facial features; calculating the fat degree RF of the face according to the parameters of the facial features; calculating heat resistant degree L according to the fat degree RF of the face; and generating a control instruction used for modulating operation parameters of an air conditioner according to the heat resistant degree L. The method can analyzes air conditioner temperature preference of a user in real time using a common face image. Compared with the prior art, a pre-established face database for recognizing the user identity is needless, determination about activity can be made without analysis on a plurality of images, a special temperature sensing camera is needless, a common camera of a common smart phone can be used for detecting temperature preference. The method and system for controlling an air conditioner based on facial features are superior to the prior art in develop cost of goods, user privacy, computational complexity of hardware, and places of applications and the like.

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 image with the image stored in the storage module of the air conditioner, 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 The corresponding relationship between air-conditioning 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 calculate the movement of indoor people by detecti...

Some methods match the extracted face image with the image stored in the storage module of the air conditioner, 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 The corresponding relationship between air-conditioning 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 calculate the movement of indoor people by detecting the position and size of faces. Calculate the amount of human activity from the amount of movement, and control the air conditioner 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; Temperature images or pictures control the operation of the air conditioner, this method needs to increase the cost of the product
