Human body heat source recognition method and device and equipment having device

Abstract

The invention provides a human body heat source recognition method and device and equipment having the device. The human body heat source recognition method comprises an image acquisition step which is used for acquiring a thermal infrared image through an infrared human sensing detector arranged in an area to be detected; and a heat source analysis step which is used for analyzing the heat source in the acquired thermal infrared image and determining the heat source as a human body heat source when the heat source characteristics in the thermal infrared image meet the preset conditions, wherein the preset conditions include that the temperature of the heat source is greater than or equal to the lower limit value of normal human body temperature and less than or equal to the upper limit value of the normal human body temperature, and the difference value of the heat source core temperature and the background temperature is greater than or equal to a preset temperature difference threshold. According to the technical scheme, the human body heat source can be accurately recognized, the human body position is monitored in real time and the recognition accuracy is high so that the position information of the human body heat source can be accurately fed back and the human body heat source area is constantly maintained to have great comfort level experience effect.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and device for identifying human body heat sources and equipment with the device. Background technique [0002] With the improvement of people's living standards, household appliances including air conditioners, humidifiers and dehumidifiers or air purifiers have become a must-have in people's daily life. However, at present, most household electrical appliances do not have the human body heat source recognition function, or the human body heat source recognition mode is single. Taking an air conditioner as an example, the conventional air conditioner has a single human body heat source recognition mode, low recognition accuracy, and easy detection errors, so that the feedback sends out wrong operation control. The effect of human comfort experience is poor. Due to the low identification accuracy of the human body heat source, it is impossible to carry out tar...
