Abstract

Accurate calibration of imaging system parameters is the basis of focal stack computational imaging system. In this paper, we set the focal plane and the corresponding imaging parameters as the preset position of the imaging systems, and define the focus measure by the Sum-modified Laplacian (SML) and feature point density to describe the focus degree of the resolution test chart. The preset positions are obtained by calculating the maximum focus measure, which can be used to realize the reconstruction of the scene depth map and the all-in-focus image. The experimental results show that the preset position calibration method proposed in this paper can achieve the high-precision reconstruction of the depth map and the all-in-focus image of the 3D scene.
