智慧型電腦動畫攝影編輯輔助系統 / Design of An Intelligent Camera Editing System for Computer Animation王柔文, Wang, Jou Wen Unknown Date (has links)
電影是門用畫面說故事的藝術,除了劇情上的編排,導演也必須思考如何運用鏡頭配置和運鏡技巧來渲染氣氛並傳達故事。電影拍攝製作上一直都是件費時費力的工程,儘管現在有不少電影後製工具,但專注在根據電影內容提升或改善拍攝手法的工具卻不多。本研究目標為開發智慧型電腦動畫攝影編輯輔助系統及互動操作平台,透過圖示化攝影機拍攝的結果作為選項的介面和推薦系統,讓使用者可以快速簡單的設置虛擬攝影機,配合智慧型回饋提醒系統檢查各鏡頭間是否違反拍攝規則,以達到輔助攝影初學者的目的,提供創新有效的動畫電影拍攝輔助工具。我們透過實驗讓不同攝影背景經驗的使用者操作,以驗證我們系統的可用性。 / Movie is the art of "storytelling." In addition to arranging story elements in a movie, a di-rector must also consider how to present the story by shots arrangement and operations. Filmmaking is a time-consuming process. Although there are many post-production tools available in the market, it is rare to find a tool focusing on facilitating shot arrangement to improve the quality of a movie. In this work, we have developed an intelligent camera editing system for computer animation, in which users can easily set up virtual cameras through se-lecting shot icons recommended by the system. It can also provide intelligent feedbacks to novice users and check if the shots selected by the users violate the rules in virtual cinema-tography. In order to show that the system is an innovative and effective tool for making an animation film, we have conducted an evaluation study by inviting participants with different photographic backgrounds to experience the system and verify the usability of our system.

互動敘事中自動產生符合情境的攝影機規劃 / Context-aware camera planning for interactive storytelling陳嘉豪, Chan, Ka-Hou Unknown Date (has links)
在互動敘事(Interactive Storytelling)的應用中,適當的攝影機規劃能幫助我們呈現虛擬世界中所發生的故事。在本研究中,我們設計了一個可以讓使用者設計互動敘事的應用平台-IMStory。針對故事創作,我們提供了一個故事腳本的描述語言及其剖析器,當使用者撰寫好互動故事之後,系統便能夠根據故事情境內容及與使用者互動的結果產生出符合情境的自動攝影機規劃系統。在此系統中,我們建立了一個能夠讓攝影機理解故事腳本的關係模型,建立虛擬攝影機組態與「故事情境」間的對應關係,即時找出更能表達當時情境的拍攝方式與架設位置。最後,我們設計了一個場景劇本進行實驗,在實驗中,我們的系統能夠即時因應場景中角色物件的位置作出即時的攝影機規劃,並且能夠配合互動環境中改變的情境參數而使用適合的攝影模組,產生出符合攝影學法則且賦有敘事能力的鏡頭。透過我們的方法,希望能提供一個更加有敘事能力的互動敘事平台。 / In an 3D interactive storytelling system, virtual camera is the key for us to understand what happens in the virtual world. In this thesis, we have designed an intelligent camera planning system for interactive storytelling, in which story plots are influenced by the user’s actions. Since the story flow cannot be determined in advance, it is essential to utilize real-time camera control to express the story for given spatial relationships between characters and objects. A script language and its parser were designed for our storytelling system (IMStory) to describe events in the story as well as the contexts associated with the events to model the properties of a story for camera control. We have developed a camera planning system by mapping contexts parameters into appropriate camera control parameters. We have implemented the 3D interactive storytelling system and demonstrated its capabilities with several examples. The camera planning system is shown to perform in real time, and the generated shots are more expressive in establishing the relation between camera configurations and story context.
