摘要
本文介绍了中心线的生成算法,用中心线描述两条线之间的协调程度具有一定的参考作用,但同时也存在一些问题,为了更好地表示线与线之间的协调程度,分析了在视觉上影响协调程度的一些因素,根据一条直线段与它的平行线是完全协调的自然规律,定义了一条度量两条线之间协调程度的标准线,并建立了协调程度的计算公式。
The central-line can be used to describe roughly the degree of harrmony between lines. In order to express the degree of harmony in a more exact way, the paper analyzes some factors which affect the character of harmony from vision, It discusses the natural law of spatial cognitive mode that it is completely harmonious between one line segment and its parallel line. Then, it defines a standard line to measure the harmony, and finally constructs a mathematic formula for the calculation of the degree of harmony between lines.
