AI Technical Summary

Problems solved by technology

[0002] With the development of AI technology, it has great market application scenarios, but at present, AI technology is rarely used in the fan market. In the existing technology, infrared sensing is usually used to obtain the distribution area of ​​the crowd, and the fan is controlled based on the distribution of the crowd. In the scanning area where the head swings, it is prone to problems such as the inability to distinguish between animals and crowds, and the identification of blind spots
In the prior art, the human sensor module is also used to determine the distribution area of ​​the crowd, but multiple human sensor modules need to be installed, which increases the cost, and there is a blind spot for long-distance personnel detection, which cannot achieve effective identification
In addition, in the prior art, the distance between the person and the camera is used to determine the position of the person, but this method cannot accurately and effectively identify the scanning area of ​​the fan swing head

Embodiment 1

[0062] see figure 1 as shown, figure 1 It shows a schematic flowchart of a fan control method provided by an embodiment of the present invention, which includes:

[0063] Step S01: Collect image information of the initial scanning area where the fan shakes its head.

[0064] Step S02: Construct a one-dimensional coordinate system based on the initial scanning area.

[0065] Step S03: Determine the number of people in the initial scanning area, the center point of the person image, and the pixel center point of the image recognized by the human figure recognition unit according to the image information.

[0066] Step S04: Based on the center point of the person image and the pixel center point of the image recognized by the human figure recognition unit, determine the orientation of the person corresponding to the center point of the person image relative to the human figure recognition unit.

[0067] Step S05: Control the human figure recognition unit to rotate to the direc...

Embodiment 2

[0098] see Image 6 as shown, Image 6 It shows a schematic diagram of the orientation of the person relative to the fan in the three states provided by Embodiment 2 of the present invention.

[0099] Wherein, the initial position of the fan is taken as the starting point, and the direction in which the fan rotates from the initial position to the right corresponds to the positive direction of the one-dimensional coordinate system. Then the position coordinate corresponding to the starting point of the fan is x f =0, if the fan turns to its right side, x f do x f ++Calculation; if the fan turns to its left, x f do x f --calculate.

[0100] see Image 6 In the distribution of a shown in , based on the center point of the person image and the pixel center point of the image recognized by the human figure recognition unit, it is determined that the orientation of the person corresponding to the coordinates of the center point of the person image relative to the human figur...

Abstract

The invention discloses a fan control method and device, a storage medium, electronic equipment and a fan, the fan comprises a human shape recognition unit; and by collecting image information of an initial scanning area of fan head shaking, on the basis of a personnel image center point determined according to the image information anda pixel center point of the human shape recognition unit, the orientation of a person corresponding to the central point of the person image relative to the human shape recognition unit is determined, a scanning area of fan head shaking is determined according to the number of persons determined based on the image information and the position coordinates of the current person in a one-dimensional coordinate system constructed based on the initial scanning area, and the fan is controlled to work in the scanning area. According to the method, the fan oscillating scanning area is automatically, accurately and efficiently located, the scanning area can be automatically adjusted along with personnel, and the beneficial effect that the fan is flexibly and intelligently controlled to work is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, and in particular to a fan control method, device, storage medium, electronic equipment and fan. Background technique [0002] With the development of AI technology, it has great market application scenarios, but at present, AI technology is rarely used in the fan market. In the existing technology, infrared sensing is usually used to obtain the distribution area of ​​the crowd, and the fan is controlled based on the distribution of the crowd. In the scanning area where the head swings, it is prone to the problems of being unable to distinguish between animals and crowds, as well as identifying blind spots. In the prior art, the human sensor module is also used to determine the distribution area of ​​the crowd, but multiple human sensor modules need to be installed, which increases the cost, and there is a blind spot for long-distance personnel detection, which cannot achieve effect...
