Photometric Stereo via Computer Screen Lighting for Real-time Surface Reconstruction
نویسنده
چکیده
We introduce a method which uses the light emitted by a computer screen to illuminate an object such as a human face from multiple directions, simultaneously capturing images with a webcam in order to perform photometric stereo. Dominant eigenvectors of the captured images provide surface normals, which are integrated into a 3D surface using Gauss-Seidel relaxation. The system runs at 10 frames per second on a consumer laptop computer.

3D fingerprint recognition is an emerging technology in biometrics. However, current 3D fingerprint acquisition systems are usually with complex structure and high-cost and that has become the main obstacle for its popularization. In this work, we present a novel photometric method and an experimental setup for real-time 3D fingerprint reconstruction. The proposed system consists of seven LED l...
متن کاملNoniterative 3D Face Reconstruction Based on Photometric Stereo
3D face reconstruction is a popular area within the computer vision domain. 3D face reconstruction should ideally be achieved easily and cost-effectively, without requiring specialized equipment to estimate 3D shapes. As a result of this, many techniques for retrieving 3D shapes from 2D images have been proposed. In this paper, a novel method for 3D face reconstruction based on photometric ster...
متن کامل3D Reconstruction of Interreflection-affected Surface Concavities using Photometric Stereo
Image-based reconstruction of 3D shapes is inherently biased under the occurrence of interreflections, since the observed intensity at surface concavities consists of direct and global illumination components. This issue is commonly not considered in a Photometric Stereo (PS) framework. Under the usual assumption of only direct reflections, this corrupts the normal estimation process in concave...
متن کاملModel effectiveness prediction and system adaptation for photometric stereo in murky water
In murky water, the light interaction with the medium particles results in a complex image formation model that is hard to use effectively with a shape estimation framework like Photometric Stereo. All previous approaches have resorted to necessary model simplifications that were though used arbitrarily, without describing how their validity can be estimated in an unknown underwater situation. ...
