Shape reconstruction from gradient data

Webb3D shape reconstruction typically requires identifying object features or textures in multiple images of a subject. This approach is not viable when the subject is semi-transparent and moving in and out of focus. Here we overcome these challenges by rendering a candidate shape with adaptive blurring and transparency for comparison with the images. We use … Webb1 apr. 2024 · Shape reconstruction from gradient Wavefront reconstruction Splines 1. Introduction Two-dimensional integration methods [1], [2], [3], [4] are widely applied to reconstruct the height or wavefront from the measured gradient data in slope metrology, such as deflectometry [5], [6] and wavefront sensing [7], [8] etc.
