Embodiment Construction

[0020] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0021] Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and / or processing steps closely related to the ...

Abstract

The invention discloses a three-dimensional model change method and device. The method comprises the following steps: comparing a target three-dimensional model of a target object with a preset reference three-dimensional model to determine a model conversion parameter, wherein the model conversion parameter is used for representing a conversion mode used for converting the reference three-dimensional model into the target three-dimensional model; and according to the model conversion parameter, converting an original three-dimensional model which needs to be converted. A conversion mode of the original three-dimensional model is determined through comparison with the reference model so as to convert the original three-dimensional model, a problem that modeling is difficult to carry out since the original three-dimensional model is different from the target three-dimensional model can be effectively overcome, remodeling and repeated calculation can be avoided, and problems of low modeling precision and high cost caused by the remodeling and the repeated calculation can be avoided, and the method and the device exhibit high flexibility and operation efficiency and can effectively adapt to constantly changing demands.

Description

technical field [0001] The present invention relates to the field of image processing, and in particular, to a three-dimensional model transformation method and device. Background technique [0002] With the advancement of science and technology, graphics and image processing technologies are also developing. Three-dimensional model construction technology is a key technology in graphics and image processing technology, and it plays a key role in many fields such as the recognition of human heads and the construction of spatial three-dimensional models of virtual objects. [0003] At present, for the construction of 3D models, the methods adopted mainly include the following three methods: [0004] The first way is to use 3D software modeling. At present, there are many kinds of modeling software on the market, and their common feature is to use some basic geometric elements (such as cubes, spheres, etc.) and use a series of geometric operations (such as translation, rotat...
