基于光纤传感器的投影图像梯形失真校正系统
An Image＇s Keystone Correction System of Fiber Optic Sensors for Projection
摘要
Abstract
Aiming at projector calibration problems with the low precision, small-scale and complicated operation of the vendors, an automatic correction system based on scanning and positioning technique was developed. Meanwhile fiber-optic sensors and Gray coding structured-light model were applied to set up the system. Compared with traditional methods, the system can not only position the spatial orientation fast and efficiently, but also be maneuverable. The test on the experimental prototype showed that the embedded optical fiber sensors can accurately detect optical signals of different coding structures, and the host computer can produce the accurate target coordinates depending on the feedback information from the transducers. Hence the effect of the keystone correction is obvious and the expected design goals of the system are achieved well.关键词
