Embodiment Construction

[0040] The present invention will be further described below in conjunction with accompanying drawing:

[0041] Such as figure 1 As shown, a preferred three-dimensional grid sequence compression method based on human body template alignment specifically includes the following steps:

[0042] S101: dynamic data collection;

[0043] S102: Obtaining three-dimensional skeleton points;

[0044]S103: preparing a parameterized template;

[0045] S104: Parametric template action alignment;

[0046] S105: Parametric template shape alignment;

[0047] S106: Construct a parameterized template grid sequence

[0048] S107: grid sequence geometry compression;

[0049] S108: Mesh sequence texture compression.

[0050] Preferably, in S101, taking a moving human object as an example, a moving human object is captured by a ring camera array composed of 56 moving cameras, see figure 2 . A frame rate of 30FPS is adopted, and the shooting time is controlled within 5-15 seconds to obtain ...

Abstract

The invention provides a three-dimensional grid sequence compression method based on human body template alignment, which belongs to the technical field of data compression, and specifically comprisesthe following steps: collecting dynamic data; acquiring three-dimensional skeleton points; preparING a parameterized template: aligning actions of the parameterized template; aligning the shapes of the parameterized templates; constructing a parameterized template grid sequence; geometrically compressing the grid sequence; and carrying out grid sequence texture compression. Model compression based on template mapping has good compression efficiency and compression quality, the storage space of a three-dimensional video with a free viewing angle is reduced, the method can be more widely applied to mobile equipment and other portable equipment, the data volume is reduced, so that the method is more suitable for mobile data transmission, and the transmission efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of data compression, in particular to a three-dimensional grid sequence compression method based on human body template alignment. Background technique [0002] With the rapid development of computer graphics and 3D scanning technology, 3D grids have been widely used in various fields such as computer graphics and computer vision. In recent years, the size and complexity of 3D grid data has gradually increased. How to compress efficiently to reasonably save network bandwidth and reduce the storage space of 3D data during data transmission has become an important and popular topic in the field of 3D data research. [0003] The 3D mesh model with vertices and facets as primitives is a way of expressing 3D models. Depending on the number of vertices, number of facets, file format and encoding method, the memory occupied by the 3D mesh model usually ranges from 1 megabyte to 100 megabytes. Tens of seconds of h...
