Infrared tracking technology based human body motion characteristic capturing system

Abstract

The invention discloses an infrared tracking technology based human body motion characteristic capturing system and provides a human body motion characteristic capturing and recognition system based on single infrared detector signals according to distribution characteristics of signals in time domains and frequency domains when human bodies moves along different paths and different directions in detection regions of infrared detectors. The system comprises an infrared tracker and a human body motion characteristic capturing data processing device. The infrared tracker comprises a single infrared detector. The human body motion characteristic capturing data processing device comprises a data acquisition module and a motion characteristic analysis module. By means of the system, the problem of drifting of other motion characteristic capturing systems caused by the fact that the systems are easily interfered during signal transmission is solved, and the capturing accuracy is greatly improved.

Description

technical field [0001] The invention relates to the use of infrared tracking technology to capture human body motion features and realize human body motion feature recognition. It specifically involves the fields of infrared tracking, motion capture, and motion recognition. Background technique [0002] In recent years, with the rapid development of computer science and sensor technology, motion capture technology has been more and more widely used in game design, motion analysis, dance acquisition, virtual reality and other technologies, and human motion visual analysis is the most active one of the research directions. The existing video and optical motion captures are the main means of analyzing human motion characteristics, especially the widely used optical motion capture. Optical motion capture can be divided into two types: active and passive. The main difference is that the active Active light-emitting devices such as light-emitting diodes are used to capture, whil...

The existing video and optical motion captures are the main means of analyzing human motion characteristics, especially the widely used optical motion capture. Optical motion capture can be divided into two types: active and passive. The main difference is that the active Active light-emitting devices such as light-emitting diodes are used to capture, while passive capture mainly uses small balls coated with special materials that will appear extraordinarily bright under the capture of the camera. No matter the equipment required for active or passive motion capture is complicated, it needs to be in Each part of the human body is marked, and various imaging devices are expensive, and the detection and recognition algorithms are highly complex and computationally intensive
