Air blowing equipment, control method and device thereof and storage medium

Abstract

The invention discloses air blowing equipment, a control method and device thereof and a storage medium. The control method comprises the following steps: acquiring three-dimensional dot matrix data detected by a TOF sensor; determining a contour classification result of the object in the current environment based on the three-dimensional dot matrix data and a pre-trained contour recognition model; and if the contour classification result is a first result indicating that the human body exists, verifying the authenticity of the first result based on the displacement variation of the three-dimensional dot matrix data within the set duration. Thus, the accuracy of the human body recognition result can be improved, the risk that user privacy is prone to being leaked due to image detection isavoided, the three-dimensional dot matrix data can further meet the requirement for fine control based on the position and distance of the human body, and therefore the intelligent control level of the air blowing equipment can be improved.

Description

technical field [0001] The invention relates to the field of blowing, in particular to a blowing device, a control method, a device and a storage medium thereof. Background technique [0002] With the development of intelligent technology, blowing equipment (such as fans, air conditioners, etc.) often detect human body based on various sensors, and control the action of actuators according to the detection results and functions. [0003] In related technologies, the human body detection technology is often based on image sensor detection, infrared pyroelectric detection or infrared through-beam detection. Among them, the image sensor detection can identify the human body, and to a certain extent, identify characteristics such as gender, age, height, etc., but the recognition rate is low, and at the same time used in the home environment, it will involve user privacy issues, which is taboo for users; Electrical detection can only detect whether there is a person, but cannot ...

AI Technical Summary

Problems solved by technology

Among them, the image sensor detection can identify the human body, and to a certain extent, identify characteristics such as gender, age, height, etc., but the recognition rate is low, and it will involve user privacy issues when used in the home environment, which is taboo for users; Electrical detection can only detect whether there is a person, but cannot identify the height of the person, and it must be combined with multiple sensors to barely achieve two-zone and three-zone recognition, which has great limitations in use; the infrared through-beam sensor can achieve height range through structural design Judgment, but it is impossible to accurately know the height of the user, and it is impossible to distinguish whether the target is a person or a static object such as a chair, sofa, cabinet, etc. At the same time, it is also necessary to consider the special requirements of the structure and space of the blower device, resulting in limited application

[0004] The above-mentioned human body detection techniques have corresponding limitations and shortcomings, and it is difficult to meet the human body detection needs of blowing equipment
