The current deals with the determination of the ‘true’ geometrical shape of the Great theatre of Ephesus, which is the largest theatre in Asia Minor. To detect the geometrical form of the theatre a precise point dataset was created using terrestrial measurements performed directly on the theatre site. The well-known ellipse and circle fitting algorithms were presented for detecting the precise geometrical shape of the amphitheatre rings. The study reveals that ellipse geometry fits well to the theatre arcs that is amphitheatre rings are generally elliptical in shape. The precise metric values of the parameters of the geometrical shape were computed to characterise theatre features.

目前的工作是确定以弗所大剧院的“真实”几何形状，这是小亚细亚最大的剧院。为了检测剧院的几何形式，使用直接在剧院现场进行的地面测量创建了精确的点数据集。提出了众所周知的椭圆和圆拟合算法，用于检测圆形剧场环的精确几何形状。研究表明，椭圆形几何形状非常适合剧场弧形，因为圆形剧场环通常是椭圆形的。计算几何形状参数的精确度量值以表征剧院特征。
