Description and recognition of plane has been processed depend on the geometry model of continental group and affine group anciently, with the development of the computer vision application, people attaches importance to the investigation of the perspective invariants, thus the investigation of perspective invariants gradually become an important problem in the computer vision.

以往人们对曲线的描述和识别大都是在欧氏群和仿射群的几何模型下进行的，近几年随着计算机视觉应用的发展，射影群下不变量的研究开始受到人们重视，所以射影变换下几何不变性的研究是计算机视觉中的一个重要的研究课题。

In Chapter 2, we will use one-parameter subgroups of the Lie group to develop a version ofNewton\'s method on an arbitrary Lie group for maps from a Lie group to its correspondingLie algebra which is independent of affine connections on the Lie group and differs fromNewton\'s method for sections on Riemannian manifolds.

在第2章中，我们主要研究关于从李群到其李代数的映射f的Newton法的收敛性。利用李群的单参数子群来给出关于映射f的Newton迭代点列，此Newton迭代与李群上的联络无关，也与第1章中研究的Newton迭代不同。

Therefore, the robust feedback linearization control is obtained.(2) For affine nonlinear systems with parameter uncertainties, a novel nonlinear state observer is constructed. Under nonlinear feedback control based on observed state, the regulated system state is guaranteed to enter and remain in a enough small neighborhood of origin.

对仿射非线性系统，考虑其参数的不确定性，设计了一种新型的非线性状态观测器，通过调节观测器和控制器的参数，可使系统在基于观测状态的控制下，调节状态到原点的一个足够小表示领域内。
