本文主要讲讲怎样用opencv画一些基本图形，这些图形包括，直线，圆，椭圆，多边形等。参考资料为opencv自带tutiol及其code。

　　开发环境：ubuntu12.04+Qt4.8.2+QtCreator2.5+opencv2.4.2

　　实验功能：

　　1.单击Drawing1按钮，将会画出atom图形，并且可以看出该图形成的过程，共分5个步骤画，每画完1个部分会自动停留1s，以便观察，然后画下一个部分，直至完成atom图形。

　　2.单击Drawing2按钮，将会画出rook图形，并且可以看出该图形成的过程，共分3个步骤画 ，每画完1个部分会自动停留1s，以便观察，然后画下一个部分，直至完成atom图形。

　　3.单击close按钮，退出程序。-In this paper, talk about how to draw some basic graphics, these graphics, lines, circles, ellipses, polygons with opencv. Reference materials comes with for the opencv tutiol and its code. Development environment: ubuntu12.04+Qt4.8.2+QtCreator2.5+opencv2.4.2 experimental feature: 1. To click Drawing1 button will draw the atom graphics, and can be seen that the formation process of the diagram is divided into five steps painting, each unfinished a part of the automatic stay 1s, to observe, and then draw a part of until the completion of the atom graphics. 2 click Drawing2 button, the rook will be to draw graphics, and can be seen that the formation process of the diagram is divided into three steps painting, every unfinished a part of the automatic stay 1s, to observe, and then painted a part of the until the completion of the atom graphics. 3 Click the close button to exit the program.
