Starting from the observation that specular reflection is a reliable visual cue for surface mesostructure perception, we propose a progressive acquisition system that captures a dense specularity field as the only information for mesostructure reconstruction. Our method can efficiently recover surfaces with fine-scale geometric details from complex real-world objects. Translucent objects pose a difficult problem for traditional optical-based 3D scanning techniques. We analyze and compare two descattering methods, phase-shifting and polarization, and further present several phase-shifting and polarization based methods for high quality 3D scanning of translucent objects. We introduce the concept of modulation based separation, where a high frequency signal is multiplied on top of another signal. This method can be used for efficient 3D scanning of scenes with significant subsurface scattering and interreflections.\u003c\/p\u003e","brand":"VDM Verlag","offers":[{"title":"Paperback","offer_id":46890702176407,"sku":"9783639206562","price":4518.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9783639206562.webp?v=1770270393","url":"https:\/\/atlanticbooks.com\/products\/new-3d-scanning-techniques-for-complex-scenes-9783639206562","provider":"Atlantic Books","version":"1.0","type":"link"}
