Design of Automatic Control System for Stage Following Spotlight Based on UWB Positioning Technology

Abstract

At present, the following spotlight on stage is performed manually. Then there are many disadvantages such as high labor intensity, unstable artistic effects, etc. With the improvement of the function of the intelligent lamps and the development of the intelligent control technology of the stage lighting, it is possible to realize the automatic control of the stage chasing lights. An automatic control system for stage following soptlight based on UWB (Ultra Wide Band) positioning technology is proposed in this paper. This system combines ultra wideband positioning technology with stage lighting control technology based on DMX512 protocol, and uses the moving head light to realize automatic chase. The stage target positioning technology and coordinate transformation are described in details, and C++ is adopted as the environmental tool for human-computer interaction design in this paper. The experiment result shows that system can achieve an automatic control system for stage following spotlight.
