本論文主軸為推廣 EK17 中所定義的幾何相機模型與多影像曲體。此外，本論文也將計算多影像曲體在 G(1,n)^m 中 的周類，以及其在 Plucker 嵌入映射下作為一射影乘積空間 (P^n)^m 中射影曲體的次數。

Our work extends the definitions of multi-image variety and geometric cameras defined in \cite{EK17}, and computes its Chow class in G(1,n)^m and its multidegree as a subvariety of $(P^n)^m$ via the Plucker embedding.
