Paper Abstract

The Fringe Projection System (FPS) and the Laser Stripe Projection System (LSPS) both have the limitations in 3D measurements. For a shiny and diffusive surface with complex shape, neither of the systems could manage it individually at a low cost. To overcome these difficulties, we propose a method combining these two ways of projections together using a laser projector, which could project fringe patterns and scanning-laser-stripes both. In this method, we obtain two disparity maps and two quality maps by FPS and LSPS, respectively. Then combine two disparity maps together by quality maps and reconstruct the surface of the object with the combined disparity map. Real experiments are carried out to verify the proposed method and to evaluate the system performance. The plain, the colored and the metal plastic mixed objects are all reconstructed successfully in the proposed method.
