3D reconstruction, surface measurement, reverse engineering
A novel image-based 3D model acquisition system using the projections of surface level curves is presented. The basic idea is similar to surface from parallel planar contours, such as 3D reconstruction from CT or laser range scanning techniques. However, our approach is implemented on a passive camera system without additional signal emission sources. The object for 3D reconstruction is placed in a water container and the level curves of the object’s surface are generated by raising the water level. The 3D surface is recovered by multiple 2D projections of parallel level curves, and the intrinsic and extrinsic parameters of the vision system. Experimental results are presented for both computer simulated data sets and real image sequences.
