Mask design for pinhole-array-based hand-held light field cameras with applications in depth estimation.
Asia-Pacific Signal and Information Processing Association Annual Summit and Conference(2016)
摘要
Pinhole-array-based hand-held light field cameras can be used to capture 4-dimensional light field data for different applications such as digital refocusing and depth estimation. Our previous experiences suggest the design of the pinhole array mask is very critical to the performance of the camera, and the selection of mask parameters could be very different between applications. In this paper, we derive equations for determining the parameters of pinhole masks. The proposed physically-based model can be applied to cameras of different pixel sizes. The experimental results which match the proposed model are also provided at the end of this paper.
