Abstract

The invention discloses a human action recognition method based on two-channel infrared information fusion, and the method comprises the following steps of: collecting a human motion video image through an infrared camera, and collecting a human motion voltage signal through a pyroelectric infrared sensor; respectively carrying out feature extraction on the collected human motion video image and human motion voltage signal, wherein human contour energy is obtained from the human motion video image and spectrum signature is obtained from the human motion voltage signal; respectively carrying out principal component analysis on the human contour energy and the spectrum signature; fusing the principal component analysis results on a feature layer; and carrying out classification and identification on the fused features through the support vector machine method combined with corresponding data in the human infrared action data base. According to the method, multi-level human action information in the infrared image is fully utilized and the human direction information in the output signals of the pyroelectric infrared sensor is fused so as to realize classification and identification on different human actions in different directions and ensure accurate action recognition rate.

Description

technical field [0001] The invention relates to a human body action recognition method. In particular, it relates to a human action recognition method based on dual-channel infrared information fusion that combines a pyroelectric sensor and an infrared camera to identify human action. It can analyze, judge and identify human behaviors, so as to assist security personnel to respond in a timely manner. Background technique [0002] Research on human motion recognition has great application value and research significance. Many famous foreign universities, companies and research institutions have carried out a series of explorations and researches on this topic, such as Massachusetts Institute of Technology, Carnegie Mellon, etc. Well-known foreign colleges and universities such as universities have set up laboratories based on computer vision and multimedia control; companies such as Nice and ObjectVideo have also successively developed some digital intelligent monitoring sys...
