摘　　要：灯光控制是舞台装置的重要组成部分。目前的舞台灯光主要依靠人力进行控制,效率以及经济性低下。因此,提出了一种基于超带宽测距算法的舞台灯光定位模型,采用基于超带宽的对称双边测距算法,并结合三边定位算法以及卡尔曼滤波进行改进,实现了一种高精度、低成本的舞台灯光自动定位追踪系统。实验结果表明,研究算法精确率为0.967;其平均误差仅为0.85 cm,其准确率相较于到达时间差定位算法与接收信号强度指示定位算法分别领先了0.179和0.372;在定位测试中,研究算法实现了对目标点位的精确定位。通过该算法的运用,能够在舞台中更加智能的控制灯光,能够为舞台灯光控制提供更加智能化以及自动化的解决方案,推动了舞台灯光控制的创新性。Lighting control is an important part of stage installation,which can shape different stage atmosphere through color,brightness and projection Angle.The current stage lighting is mainly controlled by manpower,and the efficiency and economy are low.Therefore,a stage light positioning model based on ultra-bandwidth ranging algorithm is proposed.A high-precision and lowcost stage light automatic positioning and tracking system is realized by using the symmetric bilateral ranging algorithm based on ultra-bandwidth.The experimental results show that the accuracy of the proposed algorithm is 0.967.Its average error is only 0.85 cm,and its accuracy is 0.179 and 0.372 higher than that of the arrival time difference localization algorithm and the received signal strength indication localization algorithm,respectively.In the positioning test,the research algorithm realizes the precise positioning of the target point.Through the application of this algorithm,the lighting can be more intelligently controlled in the stage,and more intelligent and automated solutions can be provided for the stage lighting control,which promotes the innovation of the stage lighting control.
