  1. A camera calibration method with co - line points is proposed, in which distortion center is located according to cross ratio invariability, and then distortion coefficients are calculated based on a line ' s central projection is a line

    摘要提出一種用共線點列標定攝像機鏡頭畸變參數的方法，先根據交叉比不變性確定畸變中心，再利用直線的中心投影仍為直線這一性質確定畸變系數。
  2. Image coordinate and galvanometer pendular angle are kept in the computer according to the f9 field lens characteristic, enter pupil excursion and f6 characteristic error are ignored, that the image of laser scanning point move acceding to unlinearity relation is deduced theoretically. for deducing the distortion, error compensation is considered in the software

    像點坐標與振鏡擺角按f物鏡特性的線性關系存儲在計算機，在忽略了入瞳漂移和f特性誤差后，從理論上推導出二維垂直振鏡分佈中激光束掃描點的像點按照復雜的非線性關系運動，為了減少幾何畸變，在軟體設計中給出誤差補償。
  3. The mutual inductor of electric current and voltage mutual inductor play an important role in relay protection. prevent from ct differential to protect and miss movement an important subject that the generatrix is protected on the saturation, put forward two electric current pass zero hour linear to spread person who become put into differential to protect in ct in recent years, avoid ct saturation district, can judge the bus bar trouble correctly

    但是在母線區外發生短路故障（特別是故障電流含有大量非周期分量）時， ct會出現飽和現象， ct飽和后，不能正確地傳變一次側電流，從而使二次電流發生嚴重畸變，產生很大的差電流，這樣就容易引起誤動作。防止ct飽和時差動保護誤動作一直是母線保護的一個重要課題，近年來提出的在ct二次電流過零時的線性傳變區投入差動保護，避開ct飽和區，能對母線故障做出正確判斷。
  4. In chapter 2, the following aspects are introduced in detail : the camera ' s pin - hole model, its distortion model, modified dlt algorithm, the programming, calibration performance of index and the designing of the experiment. moreover, several experiments are made to examine the measurement accuracy. finally, the paper discusses error analysis of this system

    在第二章里，對攝像機針孔及其畸變模型、直接線性變換（ dlt ）改進演算法、程序設計、定標性能指標等幾方面的內容都做了詳細介紹；而且，論文中詳細闡述了實驗步驟，通過幾個實際算例驗證了系統的定標精度，並做了誤差分析。
  5. In this thesis, assembler language was applied to program to realize dsp algorithm controller, which can perform such main computing as data collecting, self - adaptable distortion current detecting based on linear nerve cell, capacity voltage controlling in the side of direct current based on fuzzy control, pwm pulse width computing based on unsymmetrical rule sampling, etc. quick control speed ( one work period is 50 s ) and high accurateness feature largely in the controller

    本文採用匯編語言編程實現了dsp演算法控制器，它完成了數據採集、基於線性神經元的自適應畸變電流檢測、基於模糊控制的直流側電容電壓控制、基於非對稱規則采樣的pwm脈寬計算等主要演算法的運算。該控制器具有控制速度快（一個工作周期為50 ） ，精度高等特點。
  6. Another important content in this chapter is that we linearly calibrate the nonlinear parameters of camera based on the rectification features of lens and the fact that projective transform converts a line into a line

    本章中另外一個重要的內容是，基於透鏡畸變的特點並根據射影變換保持直線不變的約束條件，線性地確定非線性內參數。
