摘　　要：采用特征对应的视觉运动分析方法,建立了基于二次曲线的刚体纯旋转运动方程,提出了求解刚体纯旋转运动参数的算法。在刚体纯旋转运动分析中,最少利用前后两幅图像中7对匹配二次曲线,就可用线性方程组求解刚体旋转运动参数,线性算法的提出使旋转运动参数的求解精度得到很大提高。最后利用合成数据和真实图像对纯旋转运动估计算法的精度和有效性进行了验证,表明该算法能准确、可靠地估计旋转运动参数。Using the visual motion analysis method of the features, the corresponding motion equations for pure rotation based on conics are established and a new algorithm was proposed for solving the pure rotational motion parameters. In the pure rotational motion analysis for the rigid object, a set of linear equations is solved to obtain the rotational parameters at least by using of seven couple of conic matching curves in two consecutive image sequences, and it is show that this algorithm improves the precision of rotational motion parameters. The precision and validity of the arithmetic for pure rotational motion be validated by the synthesize data and true serial image. It is shown that the algorithm can accurately and credibly estimate parameters of pure rotational motion and it also makes a base for further reconstruction structure of rigid object.
