Performance Evaluation of Badminton Trajectory Error Based on Wireless Sensor Network

The successful holding of the Olympic Games has made attention to sports continue rise. China’s badminton always been at forefront world, and since became an sport, it tasked with winning gold medals. Because entry is simple, a solid mass foundation in China. Badminton very high fitness, confrontation, fun, speed as core stability, accuracy, ruthlessness, liveliness main tactical style. In professional competitions, athlete’s prediction badminton’s trajectory great significance performance game, so important. This paper aims study evaluation error analysis based on wireless sensor network. It expected predict help network technology, reduce error, improve game performance. Sensors WSN communicate wirelessly, settings are flexible, device locations can be changed any time, wired or connections Internet possible. analyzes compares commonly used dynamic target capture algorithms, advantages disadvantages this network, combines flight characteristics badminton, its trajectory. Aiming vision system monitoring, application research side detection, tracking, algorithm flying two-dimensional image plane video stream completed. experimental results show that using 2 cm not 8 cm. seen extraction strategy small.
