Embodiment Construction
[0041] The present invention aims to propose a method for realizing multi-mode automatic human body state perception, which solves the problem that the traditional technology cannot realize efficient and accurate human body state perception.
[0042] The human body recognition algorithm of the present invention includes two types of data processing modes: image analysis and temperature field analysis. The image analysis adopts the "integral channel feature + AdaBoost" data analysis method, and uses the human body feature extraction and classifier to automatically, quickly and accurately detect similar human objects through sample learning. There are two target algorithms for temperature field analysis: 1) establish dynamic environmental data to understand the background’s warm and cold state; 2) conduct longitudinal temperature field data analysis on target areas similar to human bodies, and judge the physiological characteristics of the target through the high and low temperat...

The invention relates to high-efficiency human body detection technology and quantitative analysis of human body comfort, and discloses a multi-mode automatic realization method of human body state perception, which solves the problem that the traditional technology cannot realize efficient and accurate human body state perception. The invention realizes similar human body recognition and temperature field analysis on the Arm embedded platform, and can quickly realize the similar human body target recognition through motion information and compilation optimization. Then, the infrared temperature sensor is used to initialize, identify and analyze the ambient temperature field to determine the radiation capability of the environment to similar human targets. Through the detection and calculation of human-like targets by infrared temperature sensors, and under the condition that the root mean square threshold is satisfied, the human-like authenticity of the target is determined and a mark is given. At the same time, the comfort level of the target is given by dynamically calculating the maximum temperature value and the mean value of the human body area and performing numerical comparison within a certain time difference. The present invention is suitable for human body state detection.
Description
technical field [0001] The invention relates to high-efficiency human body detection technology and quantitative analysis of human body comfort, in particular to a method for realizing multi-mode automatic human body state perception. Background technique [0002] As a research hotspot and frontier direction in the field of computer vision, human detection has been widely used and promoted in robot vision, advanced human-computer interaction and smart home. There are many kinds of human body recognition and detection technologies. From the perspective of hardware cost and detection response time, the introduction of infrared camera devices can perform image analysis on the detection data to achieve the detection goal. [0003] At the same time, quantitative analysis of human body comfort has also become a hot spot in smart homes. From the analysis of human physiological indicators, non-contact measurement of human body temperature is a better technical solution. It can be se...
