Embodiment Construction
[0044] 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.
[0045] 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 highly efficient human body detection technology and quantitative analysis of human body comfort and discloses an implementation method for multi-mode automatic implementation of human state sensing, aiming to solve the problem that highly efficient, accurate human body state sensing can not be achieved in conventional technologies. The method comprises steps of: achieving analogous human body recognition and analysis of temperature field on Arm embedded platform, and quickly implementing analogous human target recognition through exercise information and compilation optimization; carrying out initialization recognition and analysis on ambient temperature field through an infrared temperature detection sensor, so that radiation capacity of the environment on the analogous human body target can be determined; detecting and calculating the analogous human body target through the infrared temperature detection sensor; and when root mean square threshold is met, determining analogous human body authenticity of the target and providing a sign; and meanwhile, dynamically calculating maximum temperature of the human body region and mean value and carrying out numerical comparison within a certain time difference, and providing comfort level of the target. The implementation method is applicable to 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...
