Adapting Intensity Degradation to Enhance Fisheye Images Shot Inside Cup-Shaped Objects

Abstract

This chapter surveys the imaging properties inside cup-shaped objects. AOI is rarely discussed in this topic since the normally applied camera spans limited view angle and fails to capture images clearly if objects are inspected with ROI to a larger depth. Oppositely, fisheye cameras are a major issue, due to the inherently enormous scales of the focusing depth and the spanning view angle. Accordingly, closely placing a fisheye camera directly toward the bottom of a cup-shaped object, an exposure can cover the whole internal, including both the bottom and the sidewall. Through simple experimental implementation, this chapter surveyed the involved overall radial intensity degradation and the geometrically deformation profiles. The concluded photonic and morphological models are based to enhance the imaging fidelity and adapted to develop advanced images processing technologies.
