Problems solved by technology

However, this method can only perform deformation on the basis of maintaining the original structure information of the candidate model. Therefore, if the structure of the candidate model is very different from the input image, it will not be able to generate a similar 3D model.

Embodiment

[0059] The embodiments of the present invention will be further described in detail below corresponding to the accompanying drawings. First, some symbols are defined. For the foreground object in the Kinect scan data, it is defined as O, and its point cloud data and image data are defined as P and I, respectively. The set of 3D models is S, and the models in S belong to the same semantic class as O. In the model-driven point cloud and image data structure analysis, this method needs a representative model roughly retrieved from the 3D model collection defined as R.

[0060] figure 1 The main flow of this embodiment is given, and then some related concepts and methods are introduced according to the flow:

[0061] 1. First, use Internet resources to establish a candidate 3D model set, and perform consistent segmentation on the 3D model set to obtain the marked 3D model set of each component;

[0062] 2. Use the Microsoft Kinect device to scan the object to be modeled to obta...

Abstract

The invention discloses a computer three-dimensional model establishing method based on Kinect. The method comprises the following steps that a candidate three-dimensional model set is established, consistency dividing is carried out, marking is carried out, a three-dimensional model set S with parts marked is obtained; an object to be modeled is scanned with Microsoft Kinect equipment, point cloud data and image data containing the object to be modeled are obtained; an image dividing algorithm is used to form corresponding foreground objects in the point cloud data and the image data of the object to be modeled in a dividing mode; a representative model is selected, the point cloud data and the image data of the foreground objects are driven to carry out marking dividing, component parts of the foreground objects are obtained; three-dimensional model corresponding parts which have highest similarity with the component parts of the foreground objects are searched in the three-dimensional model set after the parts are marked with part-level shaped descriptors; the contour driving deforming technology and a point set data registering algorithm are used for carrying out registration on the parts and the corresponding point cloud data again so that accurate position combinations can be obtained.

Description

technical field [0001] The invention relates to the field of computer image and graphics processing, in particular to a method for three-dimensional modeling based on the existing three-dimensional model set and aiming at incomplete data obtained by single-view scanning of Kinect equipment as inspiration. Background technique [0002] Once Kinect, a somatosensory game device of Microsoft Corporation, was launched, it immediately aroused great interest of researchers in the fields of graphics and machine vision. Kinect has the advantages of low cost and easy configuration, but the 3D point cloud data it captures has high noise and low quality, and its incompleteness and ambiguity bring great difficulties to traditional 3D reconstruction methods. Therefore, how to obtain high-quality and usable 3D models based on such low-cost scanning equipment has become the latest research hotspot in the field of 3D reconstruction. [0003] With the development of modeling technology, the ...
