Processing method of geometric image and device thereof

Abstract

The embodiment of the invention discloses a processing method of a geometric image and a device thereof. The method comprises the following steps that: discrete parameterization is carried out to a natural object, and a geometric image sequence is generated; the geometric image sequence is encoded and transmitted; and images in the geometric image sequence are processed and code stream is generated. The method and the device for implementing the embodiment of the invention can solve the continuous expression problem of digital geometric data which is in a discrete structure, particularly a geometric structure and the fitting problem of expressing complicated data with explicit and implicit sample strips; simultaneously, for a specific parametric model, a multi-level parametric model with structural characteristics is built, and a complicated object can be expressed through a small number of parameters and necessary characteristics; and for the generation of the geometric images of a three-dimensional geometric model, the cutting and sewing of the high-grade geometric model as well as the low-deformation plane parameterization in a quick structure are realized.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a geometric image processing method and device thereof. Background technique [0002] The surface of a geometric object is formed by the intersection of one curved surface or multiple curved surfaces. It is extremely important to study the geometric properties of the intersection of surfaces for understanding, identifying and reconstructing objects. Flexible objects occupy a large proportion in digital geometric media, such as clothing and biomedical data. If the mainstream continuous and progressive representations are still used, the particularity of their own structures will not be fully considered. However, if parametric templates are used The representation method combined with deformation technology will bring great convenience to the subsequent encoding, transmission and retrieval. [0003] The basic idea of ​​deformed representation of digital geometric media is...

Problems solved by technology

[0006] These objects in nature are expressed as objects in computer terms. How can these objects with their own characteristics be normalized? How can we find a model and normalize all objects according to this model? This is a very difficult problem, so Model-based coding and transmission technology cannot effectively solve current problems; it cannot effectively establish a multi-level parametric model with structural features (such as feature points, feature lines, feature surfaces, etc.) for specific complex flexible objects, so as to eliminate Solve the problem of representing complex shapes with a small number of parameters and necessary features; for discrete digital geometric data, especially complex geometric structures, how to construct its continuous representation has not been resolved
