A new technique creates realistic 3D free-form surfaces from photographs and paintings

摘要

This paper presents a novel approach for creating 3D free-form scene models from a single painting or photograph with no prior knowledge about the shape. The new technique takes as input a sparse set of user -specified constraints, and generates a well-behaved 3D surface satisfying the parameters. As each constraint is specified, the system recalculates and displays the reconstruction in real time. In contrast to previous work in single view reconstruction, our technique enables high quality reconstructions of free -form curved surfaces. A key feature of the approach is a novel hierarchical transformation technique for accelerating convergence on a non-uniform, piecewise continuous grid. The technique is interactive and updates the model in real time as constraints are added, allowing fast reconstruction of photorealistic scene models. The approach is shown to yield high quality results.
