设计了一种基于摄像反馈的投影仪畸变图像自动校正系统,根据原投影图像与摄像头反馈图像之间的对应关系,建立几何变换的对应矩阵,对原图像进行预处理来抵消投影图像可能的透视失真。实验证明:该方法能有效实现投影仪透视失真的自动校正。
An automatic projector correction system based on camera feedback for projected distortion image is designed. According to the correspondence between original image and camera feedback image, we establish the homography of geometric transform, and then pretreat the original image in order to counter-act possible perspective distortion of the projected image. Experiment shows this method could effectively implement the automatic correction of the perspective distortion of projector.
