Problems solved by technology

[0004] The human body tracking technology in the prior art basically detects the human body through a single tracking method, such as the acoustic tracking module, which basically calculates and determines the detection distance by receiving the time difference of the ultrasonic wave that bounces back after emitting the ultrasonic wave. Propagation takes a certain amount of time, and when the measured part is moving at high speed, the measurement accuracy will be greatly affected, and this single tracking method is difficult to improve the tracking accuracy, and needs to be improved

Embodiment Construction

[0059] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0060] A human body tracking system such as figure 1 As shown, it includes an optical tracking module 1 , an electromagnetic tracking module 2 , an acoustic tracking module 3 and a motion sensor 4 coupled to each other, for tracking and detecting a human target to be measured. Among them, the optical tracking module 1 includes a video camera, a light source and a photosensitive diode array, and the light source can emit light to the measured human body. The optical tracking module 1 is used to obtain the tracked object according to the projection of light on the image projection plane at different times or at different positions. Azimuth, the photosensitive diode array receives the image projection of the human body at different moments or different positions under the light change, and the image projection is recorded by the video camera at the same ...

Description

technical field [0001] The present invention relates to the technical field of human body tracking, and more specifically, it relates to a method and system for human body tracking. Background technique [0002] With the development of technology, the digital display industry, which combines three-dimensional digital images and touch screens, infrared sensors, projections and other hardware, is becoming more and more mature. With digital images as the core, different display methods can be presented, emphasizing the functionality of display, experience, and interaction. During the exhibition, visitors can be connected with the exhibits through somatosensory interaction, which can further improve the intuitive experience of tourists. [0003] In some scenarios, it is necessary to track the gestures of tourists with high precision to obtain the movement data of tourists, and in some scenarios, it is only necessary to obtain the data of the overall location of tourists.
