擴增實境技術近年來快速發展，已應用至諸多產品的展示與銷售，透過虛擬穿戴技術可快速、大量試穿戴商品，整合線上與線下資源，降低實體店家庫存成本。以往基於擴增實境的虛擬試穿戴研究，較少探討人體造成的處理遮蔽問題，或是使用過於簡化的幾何模型，由於不同使用者的人體尺寸的變異，虛實遮蔽的處理效果不佳，影響虛擬試穿戴的體驗。有鑑於此，本研究針對鞋品與手提包試穿戴系統的遮蔽問題，進行較深入的探討。於現有的鞋品試穿系統中，嘗試兩種改善遮蔽效果的方法，分別基於足部深度資料點雲，以及資料迴歸近似之角錐組合，建立近似人體腳踝部位的三維幾何，並即時計算腳踝關節的旋轉軸向，調整三維幾何的空間方位，進行準確的遮蔽處理計算。另一方面，開發手提包虛擬試戴的雛形系統，採用參數化模型，透過輸入人體特徵尺寸，建立接近使用者人體幾何的遮蔽模型，即時取得手臂與上半身骨架位置，以準確定位遮蔽模型，判斷虛實物體的前後關係。於上述兩項試穿戴系統中，整合客製化設計功能，使用者可挑選不同款式的商品模型，改變其顏色、形狀與尺寸，產生對應結果進行試穿戴。最後透過不同使用情境的測試，驗證遮蔽改善方法的準確性，並討論存在的功能限制。本研究改善虛擬試穿戴技術的視覺化品質，整合即時性的客製化設計功能，將可提高擴增實境在產品開發上的實用性。

Augmented reality technology has developed rapidly in recent years, and has been applied to the display and sales of many products. We can quickly and massively try-on products throug virtual try-on technology. By integrating online and offline resources, physical stores can reduce inventory costs. In past researches about virtual try-on in augmented reality, there is less researches about solving occlusion problems caused by human body. In the past, the use of oversimplified geometric models, due to the variation of human body size of different users, the quality of occlusion is not good, affecting the experience of virtual try-on. In the light of it, this study explores the occlusion problem of footwear and handbag try-on system. In footwear try-on, this study try two methods to improve occlusion quality. First method is based on cloud points of foot depth data. Second method use foot depth data calculate rotation matrix with regression approximation, create a three-dimensional geometry that approximates the ankle of human body, calculate the rotation axis of ankle joint in real time, adjust the spatial orientation of the three-dimentional geometry, and perform accurate occlusion calculation. On the other hand, using parametric models to develop the prototype of virtual handbag try-on system. By inputting the measurements of human body, a model close to the geometry of the user’s body is created, and the position of the arm and the upper body skeleton is obtained to accurately locate the masking model and determine the distance relationship between virtual and real objects. Integrate customized design function in the above two try-on system. Users can select different styles of product, change their color, shape, and size, and produce create the corresponding model for try-on system. At the end, verify the accuracy of the occlusion improving method through different scenario, and discuss the limitation of the system. This study improve the visual quality of virtual try-on technology and integrate the customized design function, which will improve the practically of augmented reality in product development.
