Simulation And Implementation Of Human Interactive Fireworks System Based On Particle System

Simulation of natural scene has always been a hot research topic in the design and implementation of virtual reality system, which usually has irregularity and uncertainties. Particle system is recognized as the most successful one in the methods of modeling such irregular objects, and has a wide range of applications. Computer visual perception technology based on image processing is an important topic in the field of artificial intelligence, which has a good application prospects and a broad space for development.In this article, on this basis of analyzing and summarizing the current simulation of fireworks particle system in world, we combine the needs and applications of popular science production, and design a persons-interactive fireworks system based on particle system for the target of friendly, realistic and real-time system. The system that is based on particle system modeling methods and computer vision sensing technology, respectively realizes the fireworks display and the automatic identification and positioning of crowd. The changing positions of people set off the fireworks automatically to realize the function of mult-human-computer interaction.The main work and research results of this article are listed as the three follows. Use irregular movement of random particles in the system to simulate the movement of fireworks particles after the analysis of fireworks characteristics, geometric shape and motion regulations. Implement the method of head recognition and location based on Hough transform and coordinate the array of crowd location with fireworks position to achieve a natural interaction. Design and implement an interactive interface, which can be set parameters to display different styles of fireworks and so implement the human interactive fireworks particle system.
