Embedded algorithm for semi-supervised artificial intelligence human detection based on infrared array timing

Abstract

The invention discloses a semi-supervised artificial intelligence human body detection embedded algorithm of infrared array timing, which reads the infrared array data Z(t)=[z obtained by infrared array sensor detection every 300 ms ij (t)], and do Kalman filter; after obtaining the filter, the optimal solution data matrix at time t is M t =[m ij ]; compute M t The variance σ of t And the average value is used as the eigenvalue of the temperature matrix; the previous steps are cyclically calculated, and the time series of length r is stored and the average value of the temperature matrix is ​​calculated to calculate the time series R of length r t The variance of the two eigenvalues; on the basis of finding the background feature matrix, the data matrix obtained at time s is M s , calculate and judge whether there is a human state, and the mutual conversion between the human state and the unmanned state. It can better avoid privacy issues, more effectively detect and obtain human body information in a static state, has a large detection range, the detection facility is less affected by the environment, and has a high detection adaptive ability.

Description

technical field [0001] The invention relates to a human body intelligent recognition method, in particular to a semi-supervised artificial intelligence human body detection embedded algorithm in certain public scenes where it is necessary to detect and judge whether there is a human body. Background technique [0002] Usually in some scenes like public toilets, it is inconvenient or impossible to directly detect whether there is a human body in a certain behavior, and it is hoped or necessary to be able to know the data information of the human body; for example The application needs to judge whether there are people in the monitoring pit in the public toilet, so that the personnel data information is displayed on the display screen set outside the public toilet, so as to transmit to people the usage information of the public toilet location in the public toilet management system, through the public toilet The management system monitors the toilet seat usage data of public t...

Problems solved by technology

[0003] In order to solve the existing human body recognition technology, which is easy to damage the user's privacy, the hardware cost is high, the human body in a static state cannot be effectively recognized, the detection range is limited, and the detection facilities are relatively restricted by the environment, etc. The present invention provides a better To avoid privacy issues, it can more effectively detect and obtain human body information in a static state, with a larger detection range, and to a lesser extent reduce the impact of detection facilities on the environment.
