【Abstract】 By employing the imaging model of a pixel array type of a camera, e.g. CCD camera, and on the basis of the geometric model of an ellipse, the simulated ellipse image with subpixel accuracy is successively generated by the computer image simulation technique. Theoretical analysis and experimental results show that the proposed technique can generate the standard image for testing the detection precision of any one of the developed or being developed ellipse detection algorithms and that the visual effectiveness of the simulated ellipse image is continuous and smooth enough.更多还原
