Abstract


True three-dimensional display technology is a three-dimensional stereoscopic image is displayed on media technique , unlike the use of perspective , shadows, etc. In the two-dimensional display method of the conventional three-dimensional object display technology, true three-dimensional display technology rendered directly in the space of the object in three dimensions , which allows multiplayer , multi-angle simultaneously observed . This article will true three-dimensional display technology used in molecular structure , human organs , soft tissue reconstruction and display models , focusing on one of the voxel data processing research. This paper introduces the concept and classification of true three-dimensional , depending on the display technology development and application requirements, analyze true three-dimensional display technology applications in the biomedical field prospect , and then expounded the scientific principles to support the technology , given the dynamic and static images causes of true three-dimensional display . Paper then focuses on the true three-dimensional display technology voxel data processing . Multidimensional signal samples based on theory, the mathematical model to establish the sampling matrix , and the sample from the sampling efficiency relative offset distance (SRD) two aspects, the cube and the body-centered cubic (Body Centered Cubic, BCC) two sampling raster comparison ; given based criterion BCC European voxel sampling algorithm . This article also European -based criterion for the original BCC voxel sampling algorithm due to excessive amount of voxel data compressed image quality degradation caused by defects were improved ; and draw two-dimensional image quality evaluation method is proposed and objective two kinds voxel of the image for the image quality evaluation method for improving the voxels of the images before and after evaluation. Finally, the improved algorithm , in true three-dimensional display platform completed a biomedical imaging display object model verification experiment .
