Design And Development Of Networked Real-time Cycling Training System Based On Mixed Reality Technology

The intelligent riding platform and the PC-side riding training system create a realistic riding atmosphere,which replace the original mechanical riding platform and become a popular training style in the cycling circle.With the rapid development of information technology,users have put forward higher requirements for the cycling training system.The existing 3D virtual scene riding model provided by the intelligent riding training system does not meet the user's preference for riding,and the domestic riding platform can not simulate the real road feeling,lacking realism and fun.Therefore,develop richer and more interesting new cycling training models,as well as create a more realistic and accurate real-life riding experience based on mixed reality,is a new demand for the riding training system.Aiming at these demands,a networked real-life riding training system based on mixed reality technology was designed and developed based on the relevant principles.The research content of this paper is as follows:1.A real-life motion control algorithm based on mixed reality technology is designed.The algorithm uses mixed reality technology to simulate the real scene motion effects.A set of real-time video processing algorithm was developed based on related principles and techniques such as edge detection,Hough transform and perspective inverse transform.In the multiplayer game model,the virtual images of other riders in the visible range were inserted into the live video in real time,achieving the effect of chasing and being overtaken.2.Design and improvement of a networked real-time riding system,including designing its communication method,server framework and background function modules.For better compatible with the ANT+ wireless communication protocol,which is gradually adopted by the smart fitness field,a dual protocol communication method consisting of Bluetooth 4.0 and ANT+ protocol was designed to perform data interaction between the upper and lower machines.On the basis of the original single-person riding training mode,using the principle of network communication and the room production of online games and other related technologies,the server framework and the client function module were built,and the function of multiplayer competing in the same field was realized.3.The functional modules and whole system were tested on the networked live-action riding training system.The test results showed that the system had good ease of use,reliability and maintainability while achieving functional requirements.The dual protocol communication can transmit and correctly analyze the training data in real time,and the delay is less than 1 millisecond;the real-life training system can simulate a real and smooth real-time riding picture;the server can still maintain good performance when the load is greater than 200.
