Research and Application of Matrix Transformation in Position Calibration

The paper studies the position calibration of matrix transformation in the plane coordinate system, and it proposes transition matrix which uses different kinds of plane coordinate systems according to the matrix transformation to establish the method of non-redundant equation drawing from the position calibration model in different plane coordinate systems. The paper also expounds the method of solving equation with Crame Rule, which is put into use in the position calibration between the touch screen and liquid crystal display (LCD) screen in the embedded system. The result proves that using the method of matrix coordinate transformation realizes higher accuracy in the aspect of position calibration.
