Characteristic circle is adopted for characteristic mark ; a new concept, “ characteristic diameter ”, is put forward ; the length and the position of the characteristic diameter ’ s image is adopted for the basic “ characteristic parameters ” ; and a new “ resolving model ” is established based on perspective projection principle and the speciality of “ characteristic diameter ” in this article, so that the normal direction of target plane can be got without calibrating camera parameters in real time. it only need basic mathematic tools
本文採用特徵圓作為靶面上的「特徵標志」 ;提出了「特徵直徑」的概念,採用特徵直徑及其在像面上的透視投影的位置和長度作為基本的「特徵參數」 ;根據透視投影的規律,應用特徵直徑的特性,建立了新的「解算模型」 ,無須在現場標定攝像機的參數,只需採用基本的數學工具即可實時解算出靶面法線的方向。The doctors can observe the relationship and geometry of the organs and the tumors, from the 3d model of the human body, which can help them create the therapy plan. the radiation dosimetry is built using monte carlo method. after we extract the iso - surfaces from the volume of the doses, the relationship between radiation doses and the cancer is represented on a 3d model, which is greatly helpful for the doctors to improve their therapy plan
