THREE DIMENSIONAL IMAGE RECONSTRUCTION TECHNOLOGIES FOR CASTING PROCESS BY WATER MODELING

摘要

This study presents the calibration technique of multi-camera imaging system for registration of fast 3-D water filling. The goal of this system is to reconstruct of filling pattern in the mold of metal casting by water analogue modeling by capturing synchronized 2-D images. In the proposed technique, images of the calibration pattern to determine geometrical parameters of the camera were utilized. The developed technique shows stable and accurate experimental results. Proposed technique can be widely used in the areas, such as comparison of simulation results, analysis of casting defects by filling, and optimization of gating system for real casting.
