外接圆 meaning in English
circumcircle; circumscribed cicrcle
◇外接圆半径 circumradius; 外接圆心 circumcenter
Examples
- In other words , each circle has two circumscribed circles
换句话说，每个圆有两个外接圆。 - Abstract : on the basis of the way to evaluate circular degree error , the mathematic model for measuring the circular degree error are given with the least square , minimum circum circle and minimum area methods
文摘:根据圆度误差的评定方法，建立了最小二乘法、最小外接圆法和最小区域法的数学模型，并给出了其圆度误差 - In data processing , several data file format exported from measuring system has been analysis in detail , and some research has been made in these file - formats , and some try was made also . the decision standard of a thin and long triangle was discussed . besides the minimum angle of a triangle , there also the no - equlangularity and the ratio of radius of inscribed circle and circumcircle of a triangle
比如利用vc6 . 0开发了程序，可以计算三角片的法矢量、三角片的一些特征信息，以及狭长三角形的判断，特别是分析了除最小角之外的两个判断标准：外接圆和内切圆半径之比值r r ，以及三角形的不等边度e ，及它们与最小角之间的一致关系。 - Then , the minimum circumscribed circle and shape principal orientation of the object region are calculated ; and the object region is divided into some blocks in the polar coordinate , which uses the center of the minimum circumscribed circle as the origin and the direction of the shape principal orientation as the direction of the polar axis , and the features of all subblocks are extracted to compose shape histograms and then smoothed ; then , combined with global features to synthetically represent the content of the image ; finally , a new image similarity is used to compute the distance between images
首先对商标图像进行预处理,得到规则二值图像;计算目标像素的最小外接圆和图像的形状主方向;在以最小外接圆圆心为原点、形状主方向为极轴方向的极坐标中将图像分块,提取各子块特征,构成形状直方图并平滑处理;再结合全局形状特征来综合表示图像内容;最后采用新的相似性度量方法计算图像间距离,实现商标图像的准确检索。
