近幾年由於電腦顯示科技的快速進展與硬體裝置的進步，促使超高解析4K甚至8K的時代來臨，為人類的「視界」帶來了許多過去無法想像的應用。例如3D顯示由早期配戴紅藍3D眼鏡、被動式偏光3D眼鏡，到目前的頭戴式虛擬實境(Virtual Reality)、微軟公司所推出的混和實境眼鏡(Microsoft HoloLens)等，都是為了讓人們能夠感受身歷其境的視覺效果所發展出來的科技產品。這些方法都是需要戴上特殊裝置才能將3D畫面呈現出來，但全息投影(Holographic Projection，或稱全像術)是一個無須配戴裝置的裸式3D顯示方法，提供人們一種新的視覺體驗。
另一方面，由於近年來智慧型裝置的興起帶動了微型傳感器的發展，傳感器不僅越做越微小也更加精準，例如GPS模組晶片、電子陀螺儀、光學傳感器等，都有很大的進展，搭配無人機的使用，已有許多商業應用蓬勃發展例如微電影拍攝、地形偵查、建物模型建立等。無人機和一般直升機相比具有高機動性與相對低廉的成本，能夠輕易進入一些人員器具不容易或無法抵達的危險地形，且無人機同時具備了全球衛星定位系統(GPS)、自動控制飛行、即時影像回傳及資訊傳輸和高度資訊等，使得在蒐集地形地貌或是建築物資訊上更加有效率。
本論文的主要目的即結合上述兩項技術，提出建立低成本、高實用性之全息投影顯示系統(Holographic Projection Display System, HPDS)，能夠將空拍連續影像所建構3D模型，不須配戴任何3D眼鏡也能觀看立體景象。所開發系統的優點是改善全息投影價格昂貴、與必須在特定角度觀賞的缺點。

In recent years, rapid technological progress and a greater demand for high-quality digital imaging have led to dramatic advances in video display technology. A newly high resolution era is coming. "Vision World" brings many applications that we can't imagine to human. For example, 3D vision is displayed by wearing Anaglyph 3D glasses or Polarized 3D glasses, but now the equipment is replaced by Virtual Reality headset and Mixed Reality device (e.g., Microsoft HoloLens). All of the above products are designed to make people can feel the immersive visual effects, but that means people have to wear special equipment to see the 3D images. However, Holography is a new way to display 3D. People can enjoy the new visual reality experience without wearing any optical device.
On the other hand, the evolving of mobile devices pushes micro sensor to the next level. Sensors are not only smaller but also faster and more accurate. For example, GPS sensor, gyroscope sensor, and G sensor. Drones with sensors can help to develop many different business applications. Like shooting a film, terrain exploration, building 3D models, etc. Drones have better mobility and relatively lower cost than the helicopter, it can simply enter the dangerous terrain to show the area on monitor. Drones also have GPS, autopilot system, live streaming and live flight information. These would allow us to gather information of buildings or terrain more efficiently.
The purpose of this thesis is to combine these two technologies that we have described previously to design a Holographic Projection Display System with low cost and high practicability. We can use 3D models reconstructed from sequences of aerial photos watch directly through holographic projection 3D image.
