Research And Applications Of Space Positioning Technology For Interactive Equipment

With the rapid development of Internet technology and artificial intelligence technology,human-computer interaction technology is becoming more and more important.At the beginning,human-computer interaction mainly takes the mouse,the keyboard as the input device,the display is the output device.Now because of the virtual reality,enhance the reality of the fiery,the input of intelligent equipment to put forward a new request,hope to directly through the human action to complete the information input,so to be able to identify the human body or the body of a part,and positioning.Not only that,the indoor positioning technology in the location of services,public security,personnel and goods management,large data analysis,etc.there is an urgent need for application.In this thesis,the spatial location of interactive devices is realized in two ways.One is through the infrared light location method,in this paper,the structure of IR receiver is designed to judge the 2D change,and a point-to-point infrared communication system is designed to realize the communication between the interactive device and the locator,the communication frequency is 40 Hz,and the interference between infrared communication and infrared location is avoided.The product of this system has the characteristics of stability,simplicity and low cost.The other is based on the point of view of the visual positioning method,this paper studies the binocular Camera calibration method,respectively,in MATLAB and Visual Studio platform implementation.In the process of three-dimensional reconstruction,the distortion correction of the camera is c arried out,and then the space coordinate is restored by the parallel correction triangulation method and the RPNP algorithm respectively.In the process of hardware implementation of this method,the algorithm of connected domain labeling is evaluated.Ac cording to the possible interference points in the background,the elimination is realized through the image sensor and its sequential control method and exposure method.A headband is designed to realize the position of the binocular camera on the head band with the infrared marking point by the computer.
