Embodiment 1

[0028] Based on the principles of the above invention, the embodiment of the present invention provides a human body perception method, such as image 3 shown, including:

[0029] S101. Obtain a temperature detection result of a preset area by an infrared sensor.

[0030] Wherein, the preset area includes N monitoring areas, and the temperature detection result includes temperature information of the N monitoring areas. In addition, according to the distance relationship between different positions in the preset area and the infrared sensor, the preset area is divided into M first sub-areas.

[0031] Exemplary, Figure 4 It is a schematic diagram of the infrared sensor detecting the temperature of the preset area (that is, inside the house) in the scene where the infrared sensor is installed on the ceiling of the house. The infrared sensor includes a 32×24 monitoring unit matrix, which can collect 32× Temperature information in 24 monitoring areas. Wherein, the preset area...

Embodiment 2

[0046] Considering that when performing human body recognition according to the above-mentioned human body perception method and calculating the total number of human bodies in the preset area, some misjudgments may still occur. For example, when individuals stand together, only one preset mutation region can be identified by the above method, and the multiple individuals will be identified as one individual. For this reason, the embodiment of the present invention provides a human body perception method, such as Figure 6 shown, including:

[0047] S201. Obtain a temperature detection result of a preset area by an infrared sensor.

[0048] S202. According to the temperature detection result, if it is detected that a preset sudden change region exists in the preset region, it is determined that a human body is detected in the preset region.

[0049] Specifically, for the content of S201 and S202, reference may be made to the description of S101 and S102 in Embodiment 1.

Embodiment 3

[0071] An embodiment of the present invention also provides a human body sensing device, which is used to implement the above human body sensing method. For the usage scenarios of the human body sensing device provided by the present invention, reference may be made to the corresponding descriptions in the foregoing embodiments. In the embodiment of the present invention, the functional modules of the human body sensing device can be divided according to the above method examples. For example, each functional module can be divided corresponding to each function, or two or more functions can be integrated into one processing module. The above-mentioned integrated modules can be implemented in the form of hardware or in the form of software function modules. It should be noted that the division of modules in the embodiment of the present invention is schematic, and is only a logical function division, and there may be another division manner in actual implementation. In the cas...

Abstract

The embodiment of the invention provides a human body sensing method, a device and an air conditioner and relates to the field of body sensing. The precision of an infrared sensor detecting a human body can be improved. The human body sensing method comprises the following steps: acquiring a temperature detection result of a preset region by the infrared sensor, wherein the preset region comprisesN monitoring regions, and the temperature detection result comprises temperature information of the N monitoring regions; dividing the preset region into M first sub regions according to a distance relationship between different positions and the infrared sensor in the preset region; and determining that human bodies are detected in the preset region according to the temperature detection resultif a preset mutant region exists in the preset region, wherein the preset mutant region is a region comprising K or more adjacent monitoring regions mutating in temperature simultaneously in a same first sub region, and the K value corresponding to the first sub region closer to the infrared sensor in the M first sub regions is greater. The human body sensing method and device are applied to humanbody sensing.

Description

technical field [0001] The invention relates to the field of human perception, in particular to a human perception method, device and air conditioner. Background technique [0002] At present, human body sensing technology is more and more widely used in the field of home appliances. Through the human body sensing technology, household appliances can recognize the surrounding human activities in a timely manner, and perform corresponding operations according to the recognition results, so as to improve the user experience. In the prior art, infrared sensing devices are usually used to detect changes in surrounding heat sources, and the surrounding human bodies are identified according to the detection results. [0003] However, the inventors found that the existing infrared sensing algorithms generally have the problem of low recognition accuracy and prone to misjudgment. Therefore, a more optimized detection method is needed to improve the recognition accuracy of human pe...
