Embodiment 1

[0037] This embodiment provides a method for controlling a range hood, such as figure 1 shown, including the following steps:

[0038] S10. Acquire a face image.

[0039] The face image is acquired by the image acquisition device provided on the range hood. The image acquisition device can be a camera or a camera, and the acquired face image is a static image or a dynamic image. Preferably, in this embodiment, the image acquisition device provided on the range hood is a camera. Different face images can be collected by the camera, such as static images, dynamic images, different positions, different expressions, etc. can be well collected. When the user is within the shooting range of the collection device, the collection device will automatically capture the user's face image.

[0040] S20. Extract image features in the face image to perform face detection.

[0041] Extracting image features in the face image for face detection includes: selecting a certain area on the fa...

Embodiment 2

[0058] Such as figure 2 As shown, the present embodiment provides a method for controlling a range hood, which specifically includes the following steps:

[0059] S10 , judging whether there is a human body within the preset range of the range hood through human body sensing.

[0060] If so, obtain the face image;

[0061] If not, the face image is not acquired, and the range hood is not woken up.

[0062] Human body sensing can be infrared sensing or microwave sensing, and human body infrared sensing is used in this embodiment. Infrared sensing determines whether there is a human body within the preset range of the range hood, which uses an infrared sensor to detect the infrared rays of a specific wavelength released by the human body, and then senses whether there is a human body within the preset range of the range hood. When the infrared sensor detects that there is a human body within the preset range of the range hood, a face image is acquired for face detection; if ...

Abstract

The invention relates to the technical field of range hoods and discloses a control method of a range hood. The control method comprises the steps that a face image is obtained, image characteristicsin the face image are extracted for face detection, the image characteristics and the characteristics of a preset face template are compared, and whether the range hood is awakened or not is judged according to the comparison result. According to the control method of the range hood, face detection is conducted by extracting the image characteristics in the face image, the image characteristics and the characteristics of the preset face template are compared, and whether the range hood is awakened or not is judged according to the comparison result. In the control method, the situation that the range hood is mistakenly triggered due to approaching of a user or other subjective activities is avoided, the reliability of the range hood is improved, and the probability of mistaken triggering is decreased. The invention further discloses the range hood controlled through the control method of the range hood. The probability that the user mistakenly triggers the range hood can be effectivelydecreased, and the user experience effect is better.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a method for controlling the range hood and the range hood. Background technique [0002] With the development of science and technology, some humanized technologies have been applied to household appliances. The addition of these technologies has added a sense of technology to household appliances on the basis of satisfying traditional functions, making household appliances more humane, and improving people's quality of life. Human body proximity sensor, also known as non-contact proximity sensor, is an ideal electronic switch sensor, which uses infrared and microwave principles to sense human body activity information. [0003] In order to improve the humanization effect of the range hood, the human body induction sensor is applied to the control system of the range hood. When a person approaches the range hood, it will automatically wake up the range hood, so as to cooper...
