title: Multispectral photometric stereo for acquiring high-fidelity surface normals.
abstract: Multispectral imaging and photometric stereo are common in 3D imaging but rarely have been combined. Reconstructing a 3D object's shape using photometric stereo is challenging owing to indirect illumination, specular reflection, and self-shadows, and removing interreflection in photometric stereo is problematic. A new multispectral photometric-stereo method removes interreflection on diffuse materials using multispectral-reflectance information and reconstructs 3D shapes with high accuracy. You can integrate this method into photometric-stereo systems by simply substituting the original camera with a multispectral camera.
