Abstract
In this paper,with Frustrated Total Internal Reflection technology as the core and according to the technical charac?teristics of interactive display system,a fast calibration algorithm for laser multi-touch control is designed and implemented. The calibration algorithms and estimation methods of different masks produced by different light and distance in practical application sce?narios are analyzed. The system is implemented by C/C++ and NURBS surface fitting. The application results show that the algo?rithm designed in this paper has good real-time performance,stable operation effect,good user experience effect,and meets the system design requirements.关键词
