Detecting device of image correction for projector equipment

投影设备影像校正的检测装置

Abstract

A detecting device of an image correction for a projector equipment is used to solve the problem of generating a trapezium distortion of a projection image on a projection surface for the projector equipment, which consists of a position inductor keeping a vertical state under using environment and a plurality of distance-measuring components. When the projector equipment is located, a distance data to the projection surface can be obtained from the distance-measuring components, then a deviation value as a basis of the image correction for the projector equipment can be obtained by a method of geometric operations, thus an aim of trapezium correction is achieved.
一种投影设备影像校正的检测装置,用于解决投影设备投射影像至投影面上产生梯形失真的问题,它包括有一在使用环境下保持垂直状态的位置感应器以及数个设置于位置感应器上的测距组件所组成;当投影设备摆放定位后,即可通过测距组件取得至投影面的距离数据,然后再通过几何运算的方式取得偏差值,作为投影设备校正影像的依据,从而达到梯形校正的目的。
