Embodiment Construction

[0032] The present invention will be further described in detail below in combination with specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0033] The present invention proposes a texture fusion method for realizing a realistic three-dimensional model. A texture camera is used as a system component to obtain texture images of different shooting angles of an object, and then a calibration method is used to determine the mapping relationship between each texture image and the three-dimensional model; and then define different The texture function of the field of view estimates the composite weight of the texture image of the space triangle in different fields of view to smooth the color of the object surface and reconstruct the texture of th...

Abstract

The invention discloses a high fidelity full face texture fusing method of a three-dimensional full face camera, comprising following steps: calibrating multiple external parameters of a three-dimensional texture camera, projecting a triangular patch on the surface of a three-dimensional model to texture images photographed from different view angles; shearing the triangular patches projected on the texture images, calculating the fusing weight of the triangular patch on every texture image; carrying out affine transformation to all triangular patches so as to form a shape the same to the triangular patch corresponding to the maximum fusing weight; carrying out texture triangular fusion; and adhering the fused texture triangles to the corresponding triangular patches of the three-dimensional model.

Description

technical field [0001] The invention relates to the field of three-dimensional measurement, in particular to a high-fidelity full-face texture fusion method in a three-dimensional full-face camera for high-fidelity texture fusion of textures captured by multiple 3D cameras at different viewing angles. Background technique [0002] The realistic 3D model can not only accurately express the geometric shape and topological structure of the target object, but also express the real appearance of the object itself at the same time. It has important research significance and application in the fields of cultural heritage protection, architecture, film and television art, and reverse engineering. value. [0003] Only through the geometric shape (lack of surface color, material and other attributes) can not reflect the real appearance of the object, in order to obtain a realistic three-dimensional model, it is necessary to obtain and fuse the texture image. A texture acquisition cam...
