dodecagon

dodecagon

1. Ancient Chinese architecture uses a variety of shapes: the square, rectangle, triangle, hexagon, octagon, dodecagon, cross, circle, and semicircle.

中国古代建筑采用多种不同的外形：正方形、长方形、三角形、六角形、八角形、十二角形、十字形、圆形和半圆形。

2. This paper uses the idea of matrix circles model which regards the circle as a polygon (at least dodecagon), and connect the polygon edges in different ways to make up the desired filled pattern.

再以此填充模式为基础，去掉某些边则为弧段，半径的不同则可产生曲率不同的弧；

3. A Plane Pattern of Equilateral - dodecagon Based Camera Self- Calibration

基于正十二边行平面模板的摄象机自标定

4. Abstract： In this paper, we discuss a new method for camera self- calibration based on a plane pattem of equilateral - dodecagon.

摘 要： 给出一种基于平面模板摄象机自定标的新算法。
