基于Lytro相机的全聚焦成像

All-in-Focus Image Based on Lytro Cameras

由于光场相机的成像特性,单次成像不仅可以记录目标三维光线的强度信息,还可以记录目标光线的方向信息,因此光场相机可以实现图像的重聚焦。根据消费级光场相机Lytro Illum的重聚焦特性,利用重聚焦图像序列,实现光场相机的全聚焦成像。实验结果表明所提出方法的正确性和有效性,对光场相机的全聚焦成像具有较好的效果。

Due to the imaging characteristics of the light field camera,a single imaging can record not only the intensity information of the target three-dimensional light,but also the direction information of the target light,so the light field camera can generate refocusing of the image.The proposed method uses the refocused image sequence to generate the All-in-Focus image of the light field camera based on the refocus ing characteristics of a consumer-grade light field camera called Lytro Illum.The experimental results show that the proposed method is correct and effective,and has a good effect on the All-in-Focus image of the light field camera.
