Embodiment Construction

[0043] According to the three-dimensional surface data provided by the scanning system, the present invention uses weighted double-sparse constraints to register the surfaces of two deformed three-dimensional objects, thereby obtaining a complete model of the three-dimensional object. , please review to see if you can submit your application in this text.

[0044] The invention overcomes the shortcomings of the existing methods, adopts double L1 norms to constrain the position and transformation simultaneously, and obtains better registration results. Specifically, find the corresponding point of each point in the template point set in the target point set, and apply the double-sparse L1 norm to constrain the energy equation of non-rigid registration, so that the 3D surface data with deformation can be non-rigid Registration. The specific method includes the following steps:

[0045] 1) Find the corresponding point of each point in the template point set in the target point ...

Abstract

The invention belongs to the field of computer application, and aims at realizing simultaneous constraining of position and transformation and acquiring a batter registration result so that the adopted technical scheme is a non-rigid surface registration method based on weighted double sparse constraint. A corresponding point in a target point set of each point in a template point set is found, and a double sparse L1 norm is utilized to constrain a non-rigid registration energy equation so that non-rigid registration is performed on three-dimensional surface data with deformation. The non-rigid surface registration method based on the weighted double sparse constraint is mainly applied to acquire a complete model of a three-dimensional object.

Description

technical field [0001] The invention belongs to the field of computer application and relates to the acquisition of a complete model of a three-dimensional object. Specifically, it involves non-rigid surface registration methods based on weighted double-sparse constraints. Background technique [0002] In the fields of computer graphics and computer vision, non-rigid registration is an important technique applied to dynamic 3D reconstruction. This technology has very important applications in the fields of surface reconstruction and 3D object recognition. Recently, the application of depth sensors such as Kinect has become more and more widespread, but the point clouds collected by them contain too much noise, and the obtained scan data can only provide part of the information of the three-dimensional surface, and the completeness of the object can only be obtained after registration and fusion. digital model. This makes us need a non-rigid registration algorithm that is ...
