Photometric stereo image
WebJul 28, 2024 · To overcome the uncertainty from the single-image SfS, photometric stereo method has been developed to estimate the local surface orientation by using several images of the same surface taken from the same viewpoint but under illuminations from different directions . The method first recovers surface gradients from the … WebAug 6, 2024 · Uncalibrated photometric stereo is proposed to estimate the detailed surface normal from images under varying and unknown lightings. Recently, deep learning brings powerful data priors to this underdetermined problem. This paper presents a new method for deep uncalibrated photometric stereo, which efficiently utilizes the inter-image …

WebHowever, most photometric stereo methods tend to ignore factors that are relevant in practical applications. The setup considered in this paper tackles photometric stereo reconstruction in the case of a specific near-field imaging. This means that both the camera and the light sources are close to the imaged object, where close can be loosely ... Webphotometric stereo images. So, they transformed the coarse 3D mesh into a parameterised 2D space using a parameter-ization technique that reduces distortions [41]. In this work, with the aim to avoid the mapping proce-dure, we present a differential approach for MVPS. Being inspired by the signed distance function parameterisation usedbyMaieretal.
