The invention relates to an indoor personnel presence detection system based on low-resolution infrared thermal imaging. The system comprises a detection module based on a low-resolution infrared thermal imaging sensor, a communication module, an infrared collector and a host computer module; the detection module comprises the low-resolution infrared thermal imaging sensor; the communication module is in communication connection with the detection module and the infrared collector; the infrared collector is in communication connection with a host computer, and is used for transmitting data ofthe detection module to the host computer and sending a control instruction of the host computer to the detection module; and after receiving a frame of temperature distribution data transmitted by the detection module by the host computer module, the host computer module firstly calculates a variance of the temperature distribution, and judges whether a person exists in a monitoring region or notaccording to a calculation result, if yes, then the host computer module further classifies the specific activity status of the person by using a machine learning algorithm, and if not, then the hostcomputer module continuously receives the next frame of data. According to the indoor personnel presence detection system based on the low-resolution infrared thermal imaging provided by the invention, the cost is low, and a large range of simultaneous monitoring can be realized in combination with a software management platform.
Description
technical field [0001] The invention relates to the technical field of intelligent buildings, in particular to an indoor occupant presence detection system based on low-resolution infrared thermal imaging. Background technique [0002] With the continuous development of technology, the degree of building intelligence is getting higher and higher. Among them, smart home, lighting control, air-conditioning smart human sensor, security equipment, access control and other links not only need to be able to detect whether there is a human body, but also need to obtain more detailed information, such as the number of people, exercise status, physiological status, etc. Management needs to connect numerous sensor modules through a low-cost and easy-to-deploy means, and aggregate information into the central control system. [0003] There are several types of human body sensing devices commonly used today. 1. Single-point pyroelectric infrared sensor. This device uses a Fresnel lens...
