geometric imaging 中文意思是什麼
geometric imaging
解釋
幾何圖像表示-
For example, the geometric effect and vignetting are simulated with the synthetic method in which they are modeled with ray tracing and then simulated with pixel - based processing. the effects of detector noise on imaging are simulated with the three - dimension model. the theory of pixel transfer function is extended and developed, and microscanned images of four patterns are simulated with good results
本文具有如下幾個突出特點：用光線追跡法分析建模，而用基於象素處理的綜合方法，模擬了光學系統中的幾何效應和漸暈現象；利用三維噪聲模型，模擬了探測器噪聲對圖像質量的影響；對象素傳遞函數理論進行了擴展和延伸，給出四種工作模式的微掃描成像系統的象素傳遞函數的具體數學表達式，並利用這些表達式模擬了探測器的空間效應和微掃描成像的圖像效果。 -
In the imaging system, the calibration of nonlinear geometric distortion is still a problem
摘要在成像系統中，非線性幾何畸變的高精度數字校正仍然是一個未能很好解決的問題。 -
Due to the remarkable difference in hue and the big geometric deformation caused by different imaging conditions in linear ccd push - broom images, a matching method is proposed that is based on the invariant moment of histograms, two - dimension invariant moment of images, and feature weighted gray value window
針對線陣ccd推掃式遙感立體影像因成像條件不同而引起的色調差異顯著和幾何變形較大的情況，提出一種基於直方圖不變矩、圖像不變矩以及灰度加權窗口三級匹配基元的匹配方案。 -
Based on the distortion model in which the radial geometric distortion is considered as the chief factor, a general correcting method that is independent of interior parameters of the imaging system, is given and discussed in this paper via a detailed analysis of the factors which largely influence the accurate measurement of distortion parameters
以徑向幾何畸變為主的非線性幾何畸變模型為基礎，通過對影響畸變參數測量精度的各種因素的分析，提出了一種不依賴于成像系統內部參數的迭代演算法。
