Embodiment Construction

[0057] In Fig. 1, (a) a template for adding points to a square (b) a template for adding points to a cube, black points represent object points, and white points represent background points. During specific execution, if the 4 voxel points or 8 voxel points in the three-dimensional image conform to the left template in Fig. 1, they are converted into 4 or 8 voxel points in the right template. Other dot-adding templates can be obtained by rotating these two templates.

[0058] The steps of the parallel refinement in Fig. 2 of the present invention are as follows:

[0059] Step 1: Initialize the distance value. Set an integer R that represents the distance from the deleted point to the boundary. After deleting a layer point that meets the deletion condition, the integer is increased by 1 to represent the point to be deleted in the next layer.

[0060] Step 2: Release the undeleted boundary points and mark new ones. If a point in the 26-neighborhood of an object point is a ba...

Abstract

This invention relates to a framework object reassembling method including the following steps: data preprocess, parallel refinement and topology reassembling, mainly used in panning automatically and target following in vision of computer in virtual reality, image compression and rebuilding and target following. This algorism preprocesses transmission images by open operation filter and topological normalized conversion to refine the image and get its point to the boundary then carries out constructive solid coding to eliminate branches and uses a zone increase method to rebuild the original object.

Description

technical field [0001] The invention relates to the technical field of combination of pattern recognition and scientific computing visualization, in particular to a skeletonized object reconstruction method. Skeletal object reconstruction is mainly used for virtual reality, image compression and reconstruction, and object tracking. Background technique [0002] With the rapid development of data acquisition technology, the resolution of image data used in computer graphics, computer-aided design technology, geographic information system and medical image system is getting higher and higher, and the amount of data is also increasing. As a method of feature extraction and feature description, skeletonization can effectively delete redundant information and retain feature information, and can reconstruct the original object according to application requirements. In virtual reality, skeletalization can extract paths from data to guide walkthroughs and prevent getting lost durin...
