中文摘要 | 本論文研究提出「虛擬互動式食物熱量計算器」的系統設計,讓想改善飲食的人可以透過即時的互動計算出食物的卡路里,進而控制一天所應攝取的熱量,我們的系統設計目標是操作簡單、有效、吸引人,而我們利用擴增實境的技術來開發設計。在擴增實境的應用中,辨識標誌的追蹤與攝影機觀看標誌的角度有顯著的影響,當標誌卡片傾斜,攝影機俯視的角度與卡片正面驅於水平,易造成可視面積的不足,因而無法完成位置判斷或正確識別。為了克服這些缺失,本研究提出並實作一個立方體辨識標誌技術的作法,我們將六個平面的辨識標誌整合進同一群組,形成多標誌集,從應用程式的觀點來看多標誌集的操作如同單一標誌一般,但是同時只要有集合中的一個標誌被追蹤出即可成功識別,儘管立方體標誌的追蹤技術會增加系統計算複雜度,但的確可產生較為精確與穩定的追蹤成效。 |
英文摘要 | In the paper we propose a system of virtual calculator to food calories. The interactive system assists person who wants improving the diet with controlling the calories ingested a day. The system goal aims at executing easily, effectively and attractively. Thus we adopt the technique of augmented reality to fulfill this goal. Marker tracking is significant affected by its orientation relative to the camera in AR application. As the markers become more tilted and horizontal, less and less of the center patterns are visible. Consequently the recognition becomes more unreliable. We propose a cubic marker design to tackle the aforementioned problem in this study. We combine six planar markers into a multi-marker set. From an application point of view this multi-marker set is treated as a single marker. Once one or more markers of this set are visible, the tracking can be fulfilled. Despite cubic marker tracking increases the computational load, our method results in considerably more accurate and robust tracking. |
