One-Shot Scanning Using a Color Stripe Pattern

Structured light 3D scanning has many applications such as 3D modeling, animation, motion analysis, deformation measurement and so on. Traditional structured light methods make use of a sequence of patterns to obtain the dense 3D data of objects. However, few methods have been proposed to achieve pixel wise reconstruction using one pattern only. In this paper, we proposes a one-shot scanning system based on a novel stripe pattern. This pattern uses color stripes with quadratic intensity distribution in each stripe. The color distribution is based on a De Bruijn sequence with six colors and order three. Graph cut is utilized to decode the color information and the resulting code is calculated using local intensity. Compared with traditional methods, the proposed method uses one pattern only and achieves pixel wise reconstruction. Experimental results show that our one-shot scanning system can robustly capture 3D data with high accuracy.
