Test method for distortion of optical lenses used in photomask fabrication
光掩膜製作用光學透鏡畸變的試驗方法Asymmetric lens distortion
透鏡不均勻畸變差Abstract : the microstructure of as - cast high cr injection micro - alloying martensitic cast iron and the substructure of martensite in it have been observed under sem and tem. the alloying element distribution related to phase formation, as well as the various types of branch and distortion of carbide in the martensitic cast iron have been explored by using x - ray diffraction and electron probe analysis
文摘:應用掃描電鏡和透射電鏡研究了噴射微合金化的鑄態馬氏體高鉻鑄鐵顯微組織及馬氏體的亞結構，並藉助x射線衍射與電子探針分析探討了合金元素的分佈與相形成的關系，以及碳化物的不同形式分枝與畸變。Nonlinear distortion of images by digital camera is made of combined errors of lens in the camera. it is confirmed through theoretic analysis and experimental proof
通過理論分析和實驗驗證，在數碼相機成像中，二維圖像中的非線性畸變主要來自於相機鏡頭中透鏡的組合誤差。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。In chapter 5, the key algorithms of the computer vision 3 - d micro inspection system are studied. the algorithms of system calibration, image matching and correction of lens aberrance in system calibration are introduced in detail. in chapter 6, the 3 - d micro - inspection system based on computer vision is developed according to the design scheme
