摘　　要：利用双目视觉系统实现三维空间中羽毛球的实时跟踪。主要从双目图像获取、双目标定、图像校正、立体匹配等方面对双目进行探究,以识别运动中的羽毛球为导向,实现对运动中的羽毛球进行实时跟踪定位。为增加系统稳定性,采用背景减除算法和Camshift算法相结合的方法实现羽毛球在较为复杂背景的跟踪监测,再通过双目获得目标羽毛球的位置信息,再将羽毛球的位置实时反馈给机器人运动控制系统。通过不断测试,实现了羽毛球在飞行过程中的跟踪检测和轨迹三维信息的计算,并且定位误差在±10 mm范围内,实现对羽毛球的实时跟踪定位。The real-time tracking of badminton in 3 d space is realized by using binocular vision system in this paper. This paper mainly studies binocular images acquisition, binocular calibration, image correction, stereo matching and so on, to identify the badminton in sport as the target direction and realize the real-time tracking and positioning of the badminton in sport. In order to increase the stability of the system, the background subtraction algorithm and Camshift algorithm are combined to achieve the tracking and monitoring of badminton in a relatively complex background, the position information of the target badminton is obtained through binocular, and the position of badminton is fed back to the robot motion control system in real time. Through the constant testing, the tracking detection and the calculation of three-dimensional information of the flight path of badminton are realized, and the positioning error is within the range of ±10 mm, and the real-time tracking and positioning of badminton is successfully realized.
