本文提出了一种检测透视投影平面曲线对称轴的代数方法。该方法适用于隐式多项式，该隐式多项式已被拟合到通过照相机或电视机获取的2D图像数据。通过对合成图像和真实图像的实验验证，证明了该方法的有效性。
This paper presents an algebraic technique for detecting the symmetry axes of a perspectively projected plane curve. The procedure applies to implicit polynomials which has been fitted to 2D image data acquired by means of a photo camera or a TV set. The effectiveness of the proposed method has been demonstrated experimentally by using both synthetic and real images.
