Chapter 1 briefs the relation between invariance and computer vision and summarizes the research and application of invariance in computer vision. Chapter 2 first derives the transformations of three camera models, then makes the correpondences between the models and three typical geometrical transformation groups by analysing the transformations respectively. The correspondences supply the theoretical basis for applying geometrical invariants to resolve the problems of computer vision. In Chapter 3, we describe the geometrical invariant theory and prove some geometrical invariants of coplanar points, lines or conics by algebraic method. In order to use the invariants of conic pairs to describe general 2D shapes, we discuss the perspectively invariant representation of planar curves using conies in detail. A system consisted of two TMS320C25 and based on moment invariants is introduced in Chapter 5. The system can recognize more than 30 different shapes of object model or more than 10 plane models with similar shape in real time.

第一章简述了不变性与计算机视觉的关系，以及计算机视觉中的不变性研究和应用概况；第二章推导了计算机视觉中常用三种投影模型的变换关系，通过对这三种变换关系的分析，分别建立了这三种投影模型和几何学中的三种变换群之间的一一对应关系，为几何不变性在计算机视觉中的应用提供了理论基础；在第三章中，我们介绍了几何不变性的理论，并且用代数方法证明了共面点、直线、二次曲线的几何不变量和射影不变量；为了把二次曲线的不变量用于一般二维形状描述，在第四章中我们详细地讨论了用二次曲线实现一般平面曲线的透视不变性表示的方法；第五章介绍了用两片TMS320C25构成的、基于不变矩形特征的运动目标实时识别系统。

And here some indistinct recollections of the black though ingenious Cromwellian thief Sir William Petty and his double-bottomed vessel were driven clear out of his mind, for lashed to the starboard stem was a carving some six feet high, a very lively carving of three men: the first had the second standing on his shoulders and the second the third; and these three were connected by the huge penis which rose from the loins of the first, towering past the second to a point above the third man's head and held by all three as it mounted.

这时候，他再也不去回想那个聪敏的、克伦威尔式的黑人盗贼威廉。佩迪爵士了，也不去回想他模糊记得的、佩迪的双底大船了，这是因为，他看见了绑在右舷艏柱上六英尺长的非常生动的木雕，上面雕了三个男人：第二个男人站在第一个的肩头，第三个则站在第二个的肩头；而这三个男人被一根巨大的阴茎连接在一起，这根阴茎从第一个男人的腿间升起，越过第二个男人，一直升到第三个的头顶，三个人都扶着它。

Basal synthem is the Taishan mountain group in archaean, is mainly the gneiss; The paleozoic synthem besides the regional lost stratas: Upper Ordovician, Silurian-Devonian and Lower Carboniferous, other stratas have the distribution, divides into Cambro-ordovician and Permo-Carboniferous two structure subgroups. Cambro-ordovician is a set of carbonate construction, Permo-Carboniferous system is a set contains the coal clastic rock deposition; In the mesozoic synthem lost Upper Triassic and Upper Crataceous ,growth Middle-Lower Triassic and Middle-Lower Jurassic and Lower Crataceous three structure subgroups, main growth varicolored land facies clastic rock, discovered rich fossil data such as cryptogam ,Ostracoda and Chareae and so on.
