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 and the air conditioner. The method comprises the steps that a picture with a face is received, facial feature analysis is carried out on the picture, and facial feature parameters are obtained; the face fat and thin degree FFR is calculated according to the facial feature parameters; and the heat intolerance degree L is calculated according to the face fat and thin degree FFR; and a control instruction used for adjusting the operation parameters of the air conditioner is generated according to the heat intolerance degree L. According to the method and system for controlling the air conditioner based on the facial features and the air conditioner, the air conditioner temperature preference of a user is analyzed instantly through one common face picture; and compared with the prior art, the identity of the user is recognized without establishing a face database in advance, activity judgment can be generated without analyzing multiple pictures, no special temperature sensing camera is needed, and cold and heat preference sensing can be completed through a common camera of a general smart phone. The method and system and the air conditioner are remarkably superior to the prior art in the aspects of the goods development cost, user privacy, the hardware calculated amount, the application scene 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 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
