- Based on projective geometry , the research works about 3d invariance ' s extraction and application have been done in this thesis as following : ( 1 ) the basic theories and concepts in projective geometry are systematically summarized . it includes : the camera models of perspective imaging , projective collineation , cross ratio , a simple compare about invariance ( invariant ) among some geometry transformations , fundamental matrix , epipolar and epipolar line in epipolar geometry , and so on . ( 2 ) the calculation methods for 2d projective transformation are extended from points to multi - element , which includes points , lines , points lines and so on , to get the relationship between two projective planes
基于射影几何理论，论文围绕3d不变特征的提取和应用进行了如下的研究工作： ( 1 )系统总结了射影几何中的若干基础概念，包括：透视成像的相机模型、射影对应、交比不变量、基于不同几何变换下的不变量的简单对比、对极几何中的基础矩阵、对极点、对极线等。 - In this dissertation , based on the analysis of characteristics and methods of temperature control , a temperature control system has been developed for crimper machine ' s heating chests according to its " trait , and self - turning control method based on pole placement has been studied deeply . in chapter 1 , after the presentation of the object of this dissertation , the trait of crimper machine ' s heating chests is presented
本文在分析了温度控制的特点以及当前国内外在温度控制上所采用的方法的基础上，针对加弹机恒温箱控制对象的具体特点，研制了采用自校正pid策略的加弹机温度控制系统，并对极点配置自校正pid控制方法进行了较为深入的研究。
