圆明亮琢型宝石随机平衡特征的研究

Research on Features of Round Brilliant Cut Gemstones of Stochastic Equilibrium

为了对批量宝石进行图像处理,对随机放置的宝石平衡状态及特征的研究是必要的。通过对圆明亮琢型宝石几何结构的分析,讨论宝石重心位置与随机平衡的关系,得出其在台面或者亭部为支撑面时才能平衡的结论,同时处在台面时的稳定性更高。然后,分析宝石处于台面和亭部为支撑面时的图像特征,得出面积和圆形度为宝石的典型特征,并依此将宝石处在随机平衡下的状态进行分类。最后,结合图像处理实验结果对结论进行验证。

In order to batch gemstones for image processing,it is necessary to research on the equilibrium state and characteristics of gemstones. By analyzing the geometric structure of round brilliant gemstone,and discussing the relationship between the center of gravity of gemstone and the stochastic equilibrium,that gems are balanced when gems on table or on pavillion. Moreover the stability is higher on table. Then,the image features of gems were anlyzed when gems are bearing on table and pavillion,and that were concl uded the area and circular degree are the typical features of gems. According to these typical features,gems can be categorize under a stochastic equilibrium state. Finally,the conclusion was verified with image processing experimental results.
