Three-dimensional Image Reconstruction For Water Modelling of Metal Casting Processes

Abstract

Image processing techniques were applied for 3D reconstruction from several 2D images of water flow in the tasks of metal casting modelling. Low-cost image acquisition equipment was used. The optimization of the experimental set-up for video streams recording from multi points of view was made theoretically by means of the mean-square error method. The non-linear recursive method which takes into account a priori information was applied for 3D reconstruction. Experiments with a simple geometry shape mould have shown a possibility of reconstruction of surface of water and heterogeneities in it.
