Research on desktop projector touch system based on projector,infrared camera,and infrared light field
This article studies a desktop projector touch system based on projectors and infrared cameras.By adopting the principle of infrared touch scanning,the system has made significant improvements in solving the problem of insufficient operating experience in traditional televisions and projectors.The system consists of an infrared laser,an infrared camera,a main system,and a DLP projection system.The ultra short focus projector using DLP technology achieves touch screen functionality on the desktop.In terms of parameter specifications for infrared laser emitters,the setting of key parameters such as laser angle,desktop touch size,and touch accuracy ensures the touch range and performance of the system.Meanwhile,the accurate setting of the position and imaging area of the infrared camera is crucial for touch accuracy.
