Contour-aware 3D reconstruction of side-view sketches

The 3D reconstruction from a single 2D side-view sketch faces challenges in capturing details of the curves and inferring the hidden parts. Here, we introduce an approach that ensures the 2D contours are interpolated to a suitable 3D reconstruction while capturing the small details of the sketch. To this end, we propose a novel strategy that combines a proper 3D Hermitian data generation from the vicinity of the sketches with an approach for identification and completion of sketch curves. Feasible 3D models are then generated using Hermitian Radial Basis Functions (HRBF) Implicit Surfaces. Results indicate that our approach provides not only more detailed 3D reconstructed models but also more perceptual agreement from the input sketches in comparison to previous work.
