Abstract :
Interactive projection systems based on CCD/CMOS have been greatly developed in recent years for their non-contact sensing type. However, the location accuracy and tracing speed are limited by the resolution and frame rate of the CCD/CMOS. In this paper, we introduced a new type of non-contact interactive projection system based on a two-dimensional position sensitive detector (PSD). By using the PSD, both high positioning accuracy and high tracing speed can be achieved. Experimental results show that the positioning error is about 2mm over a 1200mm×1000mm projection screen, and the sampling rate is at least 200Hz.
