Abstract

In this paper, we introduce a method and algorithm for resolution enhancement of low-resolution surface topography data by fusing them with corresponding high-resolution intensity images. This fusion is achieved by linking the three-dimensional topographical map to its intensity image via an intrinsic image-based shape-from-shading algorithm. Through computational simulation and physical experiments, the proposed method’s effectiveness and repeatability have been evaluated, and the computational cost has been shown to be less than other state-of-the-art algorithms. This proposed method can be easily integrated with high-speed in-line measurements of high-dynamic-range surfaces.
