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。The latest scheme for objective analysis and mathematical model of quadratic 8 spline connecting line is using for improving analysis quality. plotting test have shown that this scheme has the characteristics such as reasonable design, high quality in map analysis
一是採用三角形、矩形面積插值方案，並加入物理原則，提高了客觀分析質量；二是聯線數學模型採用二次樣條函數，大大改善了等值線的光滑和均勻度；三是屏幕等值線修改採用人機對話方式，操作十分方便。Line, oval, and rectangle tools produce different shapes, but work the same way. when the tool is activated, click and drag to draw the shape. pressing the shift key while drawing constrains the shape to a horizontal, vertical, or 45 - degree line, or a perfect circle or square
線條、橢圓和矩形這幾種工具可繪制出不同的形狀，但操作方式是一樣的：工具激活后，單擊並拖動即可繪制形狀；拖動過程中按住shift鍵還可精確繪出橫線、豎線、 45度線、標準的正方形或圓形。The boundary curves correspond to a set of rectangular or triangular topological type that can be represented with tensor - product or degenerate b - spline surface patches
其中邊界曲線對應于可用於張量積b樣條曲面的具有矩形結構的曲線集合。分享友人
