Intensity-Based and Polarisation-Based Approaches to Three-Dimensional Scene Reconstruction

摘要: In contrast to triangulation-based methods, intensity-based approaches three-dimensional scene reconstruction exploit the pixel grey values in image recover shape of a surface or an object. Shadows multiple images acquired under different illumination conditions may contain significant amount information about (shape from shadow). The can be used determine position-dependent orientation, which by integration yields depth map shading). Making use intensity contained leads photometric stereo approach. Utilising polarisation reflected light instead its certain circumstances allows more accurate determination orientation polarisation).
