Embodiment Construction
[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0037] figure 1 This is a flowchart of Embodiment 1 of the infrared array-based human body presence detection method of the present invention. The human body presence detection method of this embodiment can detect whether a human body exists in a micro-motion / static state, and includes:
[0038] Frame acquisition step S10: acquire the temperature data of each point collected by the infrared array in real time, and form a data frame, a...

The invention relates to a human body presence detection method, device, and storage medium based on an infrared array. The human body presence detection method includes: acquiring temperature data of each point collected by the infrared array in real time, forming a data frame, and dividing the data frame into Store in the first buffer and the second buffer; obtain the current data frame and the historical data frame with a preset time interval from the current data frame, and subtract the current data frame from the historical data frame to obtain the current temperature difference frame, and Judging whether there is data greater than the first threshold in the current temperature difference frame, if so, then determine that there is a human body, and clear the first buffer; if not, then perform a static detection step; open a sliding window to obtain multiple data in the current sliding window data frames, and perform feature recognition on each data frame in the current sliding window to determine whether there is a human body. By implementing the technical scheme of the present invention, even if people in the meeting room do not move or move slightly, the occupancy state of the meeting room can be accurately detected.
Description
technical field [0001] The present invention relates to the field of infrared detection, in particular to a method, device and storage medium for human existence detection based on an infrared array. Background technique [0002] At present, many places need to know their occupancy status in real time to improve the use efficiency. For example, it is necessary to detect the presence of people in the conference room in real time, and then determine whether it is occupied. In addition, because these places involve privacy, it is not convenient to install cameras, and other technologies must be used to detect human presence. Infrared radiation detection is currently the most used method, which has the advantages of low cost and mature technology. [0003] The current infrared radiation human body detection algorithms are all dynamic detection, that is, rely on the movement of the human body, but many times, when people are in a meeting in the conference room, they do not move ...
