Firstly, the paper introduces the development and application of computer graphics & image technique, discusses the principle and method of cg and digital image processing, such as matrix of the graphic transformation, homogeneous reference frame, sampling and quantization of the image, file format of the image, template operation, etc. secondly the paper introduces the purpose and method of image enhancement processing, explains the each occasion of those methods such as threshold transformation, smoothing processing, sharpening processing, analyzes and contrasts the processing results of object image. thirdly, the paper introduces the method of mathematics morphologic, edge detection and thinning processing, attains character description of image and character dots of the contour. fourthly, the paper processes the coordinate transformation to character dots and basic splines fitting, imports correlative condition to devise meshing line and meshing track
本文首先介紹了計算機圖形圖像技術的發展與應用情況，對計算機圖形學和數字圖像處理的一些基本理論和方法如圖形變換矩陣、齊次坐標系、圖像采樣和量化、圖像文件格式、模板操作等內容進行了討論：然後對圖像增強處理的目的和方法進行了介紹，對諸如閥值變換、平滑處理、銳化處理等方法的應用場合進行了說明，並對實物圖像的處理結果進行了分析與比較；接下來介紹了數學形態學方法、對增強后的圖像進行邊緣檢測的方法和圖像的特徵描述方法，並獲取輪廓的特徵點：隨后對獲取的特徵點進行坐標變換，並進行b樣條曲線擬合，引入相關條件生成齒輪副的嚙合線及嚙合軌跡：最後引入等值線和區域填充表示方法，並以等值線和區域填充的形式對弧齒錐齒輪嚙合模擬的載荷分佈情況進行了直觀的表示。At the same time, the " stop - hop - stop " approximation is no longer valid in sas due to the low speed of sound. the receiver has unavoidable movement, when echoes get to receiver from different distances. in order to overcome the problem, an image forming algorithm of multi - aperture sas is presented in the thesis, which is suitable for the case of non - " stop - hop - stop "
為了解決測距、測速模糊問題， sas通常採用多子陣技術，而且由於sas 「停?走?停」假設往往不再有效，即測繪帶內不同距離回波到達基陣時，基陣存在不可忽略的運動，所以論文提出了一種「停?走?停」假設不成立條件下的多子陣合成孔徑聲納逐點成像演算法以得到相位保真度更高的復圖像。When x - ict detects large industrial parts and requires high resolving power, image reconstruction of x - ict has huge pixel matrix and the amount of calculation increases greatly resulting in much more time of image reconstruction. this paper proposes the parallel image reconstruction based on workstations cluster to solve fast image reconstruction of high power x - ict this paper presents the relevant basic theories and principles of ict and image reconstruction, including scan mode and image reconstruction algorithm. high power x - ict which adopts powerful beeline accelerator as radial source often uses narrow fan - beam scan mode
工業ct機檢測對象為大型工業構件並且要求高解析度時，圖像重建的像素點陣巨大，計算量大大增加，從而圖像重建時間過長。本論文提出用在工作站機群上的多機并行工作的并行圖像重建解決高能x射線工業ct機的快速圖像重建問題。本論文介紹了工業ct和圖像重建的基本理論、基本原理等有關內容，包括掃描方式和圖像重建演算法。
