摘要

本論文是利用環景接圖的技術在HoloAD顯示平台上顯示出Holography影像，而特別針對在輸入影像前處理的部份做色彩校正的研究，接著找出輸入影像的特徵點並互相匹配，最後合成出一張全景圖，然後顯示在HoloAD平台上，而色彩校正會使環景接圖後的影像更加自然，顯示Holography影像的效果能更明顯，之後可針對使用者不同的需求來完成實現不同的系統，像是可當成展示商品的顯示器，讓觀賞者可以看到商品360度的全貌，另外還可結合互動的功能，達到更好的效果。
在硬體實現上，針對演算法中所提出基於全景接圖色彩校正的部份實現成晶片，且整體架構採Low Power的設計，可以節省25%的功耗，所實現的晶片非常適合應用在行動裝置上，延長其使用時間。

This thesis uses panorama technology to display a holography images on the HoloAD platform. We adopt color correction method to perform image pre-processing and then find the feature points of the input image and match with each other. Finally, images will be blent a panoramic image and then be displayed on HoloAD platform. Color correction skill makes panorama appearing a more natural display holography image. It can be more obvious after the user may be different requirements for completion of the implementation, such as a monitor can display of goods, so that the user can see a 360-degree panorama of goods, in addition to interactive features can be combined to achieve better results.
On the hardware implementation for the proposed algorithm in color correction of panorama implemented as part of the chip, and the overall architecture adopts low power design, it can save 25% of power consumption, implement very suitable for applications in chip on mobile devices to extend their use of time.
