:Laser demonstration technology can project a variety of vector graphics including light beams,patterns and characters by changing the trajectory of laser beam in space,thus forming a unique artistic effect.A full-color intelligent laser demonstration system based on vector graphics was designed and realized on an embedded system platform.The system has multiple control methods including voice control and DMX control,and it can realize the full-color laser show through the superposition principle of three primary colors.The system controller can quickly extract and analyze node color information and route coordinates,and thus can accurately control the RGB laser and high-speed X/Y galvanometer.
