摘要
文中通过对多圆图像的Radon变换曲线的分析 ,建立了用少量的投影数据 (理论上只用两个角度的投影数据 )重建多圆图像的最佳椭圆线方法 ,并针对自定义的一个多圆图像给出了重建结果。
By analysing the Radon-transform of multi-circles image, a new algorithm called optimal-ellipse-curve for reconstructing multi-circles image was proposed. Theoretically,the new algorithm only needs two angle's projection data. In addition, an example of multi-circles image with five different circles and the reconstructed result have proved the validity of the new algorithm.
