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.
