Computer graphics ( cg ) provides a method of representing a three dimensional object in computer
計算機圖形學提供了一種在計算機上描述三維物體並且能夠展現在用戶面前的一種方法。 -
With the development of computer technology, computer graphics technology develops swift and violently. the clipping of graphics is the most basic contents in cg. it is a useful tool in algorithms about hiding line, hiding face and showing of third dimension graphic
隨著計算機技術的迅速發展，計算機圖形學技術得到迅猛發展，圖形的裁剪是計算機圖形學中最基本的內容之一，它在消除隱藏線、隱藏面及真實感圖形的顯示等演算法中是很有用的工具，以往對裁剪演算法的研究主要集中在裁剪直線和裁剪多邊形兩方面。 -
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。 -
