透镜畸变 meaning in English

lens distortion

Test method for distortion of optical lenses used in photomask fabrication
光掩膜制作用光学透镜畸变的试验方法
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
本章中另外一个重要的内容是，基于透镜畸变的特点并根据射影变换保持直线不变的约束条件，线性地确定非线性内参数。
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
第五章对视觉三维微检测系统的关键算法作了深入研究，提出并详细阐述了系统的定标、图像匹配以及定标中透镜畸变的纠偏算法，第六章根据视觉微检测系统设计方案实现了视觉三维微检测系统，并进行了微构件的测量实验和误差分析工作。
