Photometric stereo 원리

Photometric stereo is a technique in computer vision for estimating the surface normals of objects by observing that object under different lighting conditions. It is based on the fact that the amount of light reflected by a surface is dependent on the orientation of the surface in relation to the light source and the … See more The classical photometric stereo problem concerns itself only with Lambertian surfaces, with perfectly diffuse reflection. This is unrealistic for many types of materials, especially metals, glass and smooth plastics, … See more • Photoclinometry • Photometry • Stereo vision • 3D scanner See more WebJul 21, 2024 · Star 34.

GPS-Net: Graph-based Photometric Stereo Network - 知乎

WebPhotometric stereo is a form of structured lighting that increases the information available from surface reflectance variations. Basically, instead of taking a single monocular image of a scene illuminated from a single source, several images are taken, from the same vantage point, with the scene illuminated in turn by separate light sources. WebPhotometric stereo itself only provides surface normals so one needs to integrate those to get a height field / depth map, which means you won't be getting absolute depth information, just a bumpy surface which has the same surface normals as your scene. It makes the most sense for uniform textureless surfaces with no self-occlusions. dwp ir office https://puntoholding.com

Photometric Stereo and Process - Euresys

Webphotometric: [adjective] of or relating to photometry or the photometer. WebPhotometric stereo is a technique to estimate depth and surface orientation from images of the same view taken from different directions. Theoretically, only three directions are sufficient to obtain normals, but to minimize noises inherent in the process, more than minimum number is often required for realistic images. ...
