摘要
为了提升排球视频中的对于目标的追踪能力的准确性,本文利用Mean shift算法,提出了一种高效率并且又稳定的运动目标跟踪检测算法。算法根据排球在x、y轴上的坐标位置和排球在在x、y上的速度,进行观测向量的设置,并求解观测值。实验过程中采用五台摄像机对排球运动场进行全方位的目标跟踪,最终求解得到排球在三维空间的运动轨迹。实践证明,本文算法图像处理信噪比高,时间复杂度低。
To improve the accuracy of the target tracking in volleyball video, using the Mean shift algorithm, propose a detection algorithm of tracking moving target with high efficienvy and stable. Algorithm in this paper according to the position of volleyball in the x, y coordinates and speed of volleyball in x, y coordinates, carries on the observation vector, and solve the observed value. Five cameras used in the process of experiment of volleyball playground for a comprehensive range of target tracking, finally obtain the trajectories of volleyball in three-dimensional space. Practice proves that the image processing of the algorithm has high signal-to-noise ratio, low time complexity.
