Three-dimensional modeling method and device

Abstract

The embodiment of the invention provides a three-dimensional modeling method and device. The method comprises the following steps: acquiring an image which is acquired by image acquisition equipment in real time and comprises a target object, wherein the image comprises depth information; performing three-dimensional modeling on a target object according to the first N frames of images to obtain athree-dimensional model of an initial known part of the target object; matching the three-dimensional model of the initial known part with a plurality of models in a model library, and determining athree-dimensional model of an initial unknown part of the target object according to a matching result; and tracking the target object by using the images after the first N frames of images, and updating the three-dimensional model of the initial known part and / or the three-dimensional model of the initial unknown part of the target object according to the tracking result. According to the methodprovided by the embodiment of the invention, the calculation amount of three-dimensional modeling is greatly reduced, and the processing efficiency of three-dimensional modeling is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of computer technology, and in particular to a method and device for three-dimensional modeling. Background technique [0002] With the development of computer technology, 3D modeling based on the data collected by RGB-D cameras is widely used in various application scenarios. [0003] Taking data collection with a single RGB-D camera as an example, unless the camera rotates around the target object once, or the target object rotates once within the camera's viewing range, the camera cannot collect the full-angle data of the target object, and the target object cannot be established. A complete 3D model of an object. [0004] Therefore, in the prior art, if a complete modeling of the target object is required, it is necessary to wait for the full-angle data of the target object to be collected, and then use all the collected data for modeling, which requires a large amount of calculation and low...

[0003] Taking data collection with a single RGB-D camera as an example, unless the camera rotates around the target object once, or the target object rotates once within the camera's viewing range, the camera cannot collect the full-angle data of the target object, and the target object cannot be established. A complete 3D model of the object

[0004] Therefore, in the existing technology, if a complete modeling of the target object is required, it is necessary to wait for the full-angle data of the target object to be collected, and then use all the collected data for modeling, which requires a large amount of calculation and low efficiency
