摘要: 
3D立體拍攝系統主要可以分為兩種方式:(1)陣列式攝影機與(2)深度攝影機。陣列式攝影機是使用多架平行擺設的攝影機(最少兩架)同時拍攝
,在拍攝的過程中攝影機必須進行校正、同步、光線色彩變化,在拍攝的時候相當費力。深度攝影機的拍攝方式則是使用一部傳統的攝影機搭配一部深度攝影機拍攝,利用所打出的紅外線打中物體的反射時間,計算出物體與攝影機之間的距離。問題是傳統攝影機與深度攝影機也同樣需要校正
,此外深度攝影機目前也有尚未普及的問題。

本研究主要開發出新式的3D立體拍攝系統。利用新型相機:光場相機,可在拍攝事後影像可任意對焦的特性,將數個不同焦點的影像進行影像融合技術,計算出一張全清晰影像,以及影像內部各景物之間的相對距離之深度資訊。用此方式就不會有所謂攝影機校正問題,並以實際影像的資料來進行實驗,實驗結果顯示所提出的方法是有效的。

3D stereoscopic shooting system can be divided into two types: (1) array-type camera, and (2) depth camera. Array-type camera is to use multi-frame parallel to the camera (least two) while shooting. In the process of filming, the camera must be calibrated, synchronized light color changes, which is quite laborious. Depth cameras include a traditional camera and a depth camera. The depth camera hits the object by an outgoing infrared light and collects the reflection time to calculate the distance between the object and the camera. The problem is that the traditional camera and depth camera also need to be corrected. In addition, the depth camera is also not widely available yet.

In this research, a new 3D stereoscopic shooting system is developed. With the new camera, light field camera, which has the feature of adjusting its focus after shooting, we can calculate the all in focus image based on the synthesis of several images with different focus. The depth information of the scene in the image can also be obtained. In this way there will be no camera calibration problem. We have used real image data to perform experiments. The experimental results show that the proposed method is effective.
