3D Model Acquisition Based on Projections of Level Curves

摘要

A novel method for 3D model acquisition based on projections of level curves is presented. The idea is similar to surface from parallel contours. However, different from CT or laser range scanning for range data acquisition, our approach is implemented on a low-cost passive camera system. The object is placed in a container and the level curves are generated by raising the water level. The 3D surface is recovered by multiple 2D projections of parallel level curves with camera pose estimation. Furthermore, the complete 3D model is reconstructed by registration and integration of multi-view 3D shape acquisition. Experimental results are presented for real image sequences. The average error is less than 3 mm in the working range of about 1 meter from the camera
