Laser Visual Effects System for Moving Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual effects arrangements for live performances, such as theater and illusion shows, struggle with timing and accuracy when trying to project images or videos on moving objects, as they often fall behind the target and require a close projecting range, limiting the design and mounting of projectors and restricting the creation of real-time effects.
Innovation Solution
An arrangement comprising light emitting members, an imaging means for locating these members, a computing unit for real-time location data processing, and a laser projector, with a partially reflecting mirror to accurately project laser beams onto moving targets, allowing for precise visual effects even at varying distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional projectors are used to project images on moving objects, then the projections can be displayed, but the timing and accuracy fall behind the moving target
Solution Approach 1:
The patent replaces conventional mechanical projectors with a laser-based projection system controlled by real-time imaging and computing. The imaging means captures the position of light emitting members on moving objects, the computing unit calculates the required laser projection parameters, and the laser projector delivers precise visual effects in real-time, eliminating the timing lag of conventional projectors
Solution Approach 2:
The system implements a feedback loop where the imaging means continuously tracks the position of light emitting members on moving objects, sends position data to the computing unit, which then adjusts the laser projector's output accordingly. This closed-loop feedback ensures the projection remains accurately synchronized with the moving target
2Adaptability or versatility
If projectors are mounted at a distance to allow flexible space design, then the mounting restrictions are reduced, but the projections become less sharp
Solution Approach 1:
The patent changes the fundamental parameters of the projection system by using laser light sources instead of conventional projector bulbs, and employing real-time computational adjustment of projection parameters based on detected target position and distance. This allows sharp projections to be maintained at various distances, providing mounting flexibility while preserving projection quality
3Productivity
If conventional projectors are used for live performances, then visual effects can be created, but real-time effects on randomly moving objects are difficult to achieve
Solution Approach 1:
The system replaces conventional projection mechanisms with a laser projection system that can be precisely controlled in real-time. The combination of imaging means for tracking, computing unit for real-time calculation, and laser projector for immediate visual output enables accurate real-time effects on randomly moving objects that conventional projectors cannot achieve

Function Achieved in This Case
Enables real-time, accurate visual effects on moving targets, allowing for more engaging live performances and the creation of complex illusions, as the system can maintain sharp projections from longer distances and adapt to changing target positions.
Implementation Method 1
