A Method of Improved Automatic Light Tracing

Abstract

At present Auto-Tracking technology attracted increasing attention in the field of stage lighting. Most of the existing automatic lighting tracing methods adopt indoor positioning technology to acquire the location parameters of the tracing object. Then the location parameters were converted into the control data of moving light for automatic tracing. The main problems are as follows: one is the positional errors of special light position such as front light and fixed-point light. The other is the miss tracking of moving targets. In this paper, according to the projection requirements of front light and fixed-point light, the existing tracing model is improved. The error between the spot and the actual position is analyzed. Test results show that the accuracy of the upper left and upper right directions is relatively high. The bigger the curvature amplitude is, the bigger the error is. At the same time, the test data provide theory evidence for the setting of the tracing light position and the design of the performance route.
