spline fit meaning in English
花键配合
样条拟合
Examples
- The cross section data were fitted and the covariance data were combined for each reaction channel by using the spline fitting program ( spc ) developed at cndc
利用中国核数据中心的spc程序对每一个反应道的各家数据的截面进行拟合、协方差进行合并。 - As the basic concept , the first step is to modeling by ug . there is different model between propeller and commonly hardware , so we must be use curve modeling , at the same time , characteristic modeling and entity modeling in the whole process . first , we apply offset data for spline fit curve , then scanner smooth curve face
首先在三维绘图软件ug中对螺旋桨及叶片进行三维建模,由于螺旋桨的造型不同于一般零件的cad造型,故在造型过程中同时采用了曲面造型,特征造型和实体造型几种方法,先由型值数据生成样条曲线,再由样条曲线扫掠生成平滑的曲面,最后通过圆整?延伸得到螺旋桨的三维模型。 - 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
本文首先介绍了计算机图形图像技术的发展与应用情况，对计算机图形学和数字图像处理的一些基本理论和方法如图形变换矩阵、齐次坐标系、图像采样和量化、图像文件格式、模板操作等内容进行了讨论：然后对图像增强处理的目的和方法进行了介绍，对诸如阀值变换、平滑处理、锐化处理等方法的应用场合进行了说明，并对实物图像的处理结果进行了分析与比较；接下来介绍了数学形态学方法、对增强后的图像进行边缘检测的方法和图像的特征描述方法，并获取轮廓的特征点：随后对获取的特征点进行坐标变换，并进行b样条曲线拟合，引入相关条件生成齿轮副的啮合线及啮合轨迹：最后引入等值线和区域填充表示方法，并以等值线和区域填充的形式对弧齿锥齿轮啮合仿真的载荷分布情况进行了直观的表示。
