EVALUATION OF 3 D RECONSTRCUTION USING MULTIVIEW BACKPROJECTION

This paper evaluates the final reconstruction quality of 3D objects from different reconstruction methods by comparing rendered views of a 3D model to the original views, initially taken from 2D cameras. The paper uses pixel-by-pixel error measures, like pixelwise reconstruction error for non-textured objects and PSNR values for colored or textured objects. Concurrently, the limitations of such measures in connection with 3D reconstruction evaluation are highlighted and a reconstruction measurement based on differential values is investigated, where deviations from reference values are analyzed instead of absolute PSNR-values.
