Abstract

The invention discloses a multi-resolution volume rendering method based on intra-block interpolation. The multi-resolution volume rendering method based on the intra-block interpolation comprises the steps of data partitioning, blocking detail level selecting, secondary index establishing and volume rendering. The multi-resolution volume rendering method based on the intra-block interpolation has the beneficial effects that the introduction of extra data size and extra data preprocessing is avoided and the blocking effect of multi-resolution volume rendering is eliminated by use of intra-block border interpolation, and interpolation is completed by use of a GPU, and therefore, the volume rendering method is simpler and more efficient.

Description

technical field

[0001] The invention belongs to the technical field of volume rendering methods, in particular to a multi-resolution volume rendering method based on block interpolation. Background technique

[0002] Volume rendering is a technique for producing a two-dimensional image on the screen directly from a three-dimensional data field. A digital image corresponds to a two-dimensional array that describes the color and light intensity of data elements called pixels. Similarly, a three-dimensional data field can be described by a three-dimensional array with corresponding values ​​called voxels. Similar to the two-dimensional raster of digital images, the volume data field can be regarded as a three-dimensional raster. A typical three-dimensional data field is a three-dimensional data field of medical images. A series of medical image slice data are obtained by CT (computed tomography) or MRI (magnetic resonance) scanning, and these slice data are regularized accordi...
