Stage lighting tracking is a common form of expression in stage art performances,which plays an important role in illuminating the stage area and setting off the stage atmosphere.At present,the common stage lighting control requires manual operation,which is time-consuming and labor-intensive,the system is complex,and the safety is low.Therefore,this paper proposes to combine positioning technology with coordinate transformation technology for stage lighting positioning tracking to realize intelligent automation of lighting control.This paper analyzes the development of positioning technology at home and abroad and the research status of stage lighting control technology,analyzes the principle of common positioning algorithm and coordinate system conversion technology,and studies the following technologies according to the requirements of automatic positioning and tracking of stage lighting:(1)In order to realize the rapid verification and parameter debugging of the stage positioning algorithm,the common characteristics of different stage environments are extracted,and the stage positioning algorithm simulation platform is constructed.The stage positioning algorithm is verified simultaneously on the simulation platform and the laboratory environment.Finally,it is concluded that the stage positioning algorithm simulation platform is universal,which provides a fast simulation verification platform for the stage positioning algorithm.(2)Improve and optimize the positioning algorithm for special scenes of stage positioning applications.The map interpolation algorithm realizes the rapid construction of fingerprint maps;the WKNN algorithm further improves the positioning accuracy on the basis of the KNN algorithm;the triangulation algorithm simplifies the system positioning calculation while ensuring a certain positioning accuracy;the Kalman filter algorithm realizes adjustable parameter filtering on the positioning results to improve the accuracy of positioning;the map matching algorithm can correct the location points with large deviation in positioning results.(3)In view of the situation that the positioning base station,the anchor point and the stage light are in different coordinate systems,the coordinate system of the positioning point and lighting coordinate system is unified,and the rotation direction and rotation angle of the lamp are calculated,and the realization of the stage light tracking is simulated and analyzed.This paper proposes to build a stage positioning algorithm simulation platform,and it has been verified through many experiments that the simulation platform can be used for simulation of stage positioning algorithm,which provides great convenience for subsequent stage positioning algorithm research.The improved stage positioning algorithm can meet the performance requirements of stage lighting positioning in terms of accuracy and precision.At the same time,the stage lighting tracking algorithm can provide a rotating reference for the movement of the lamp.
