Fast projection based depth for focused plenoptic camera

The focused plenoptic cameras capture the scenes by one snap, which means calibration is not required. Therefore it is a great advantage to obtain the depth information. However, the existing algorithms to obtain the depth information are complicated and time consuming. In this paper, we put forward a depth measurement method based on the data obtained by focused plenoptic camera. The simulation experiment proved that this method is time-saving and has a good performance compared with the classical method.
