Abstract: A method of image distortion by using direct linear transform algorithm is provided to correct the distortion of the screen image provided by a camera by using the actually measured data obtained by the camera. A grid is displayed in the real video to map Xw, Yw and Zw which are coordinate values of X, Y, and Z of the real images on X and Y coordinates of the screen images(S101). The actually measured data, which is the grid node value of the X and Y shafts is obtained by obtaining the image from the generated grid and regenerating a distance reference line(S102,103). The X and Y coordinates are obtained from the actually measured data to fix the Y shaft and to calculate the function pitted to the X shaft direction(S106). The pixel function is generated by generating the total function of the pixel X function(S107). The factor function is obtained by calculating the Polynomial factor value, and the pixel Y function is generated by generating the total function of the pixel Y(S113).
