Problems solved by technology

If you want to get finer details, you often need to set a higher resolution, and the amount of data will expand dramatically. Low resolution reduces the amount of data, but cannot present the details of complex models.

Abstract

The invention relates to an intelligent multi-resolution feature optimization three-dimensional reconstruction method and system, and the method comprises the steps: setting a first resolution and a second resolution, and enabling the first resolution to be lower than the second resolution; performing reconstruction based on the first resolution by using the original three-dimensional scanning data to obtain a low-resolution model, calculating the curvature of each three-dimensional point in the low-resolution model, and marking the three-dimensional points of which the curvatures are greater than a set curvature threshold as feature points; performing reconstruction based on a second resolution by using original three-dimensional scanning data in a set area range taking each feature point as a center to obtain a triangulation network; stitching the triangulation network into the low-resolution model to obtain a three-dimensional reconstruction model; according to the method, a feature region is reconstructed with a higher resolution, a plane region is reconstructed with a lower resolution, and boundary regions with different resolutions are automatically merged, so that a good visual effect of a detail part can be considered at the same time, a larger dot spacing or triangular mesh is kept on a plane, and the size of exported data is reduced.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, in particular to a three-dimensional reconstruction method and system for intelligent multi-resolution feature optimization. Background technique [0002] In the process of 3D reconstruction technology, the generated result data generally has a fixed resolution, and the point spacing of the point cloud or the size of the triangular surface is uniform. If you want to get finer details, you often need to set a higher resolution, and the amount of data will expand dramatically. Low resolution reduces the amount of data, but cannot present the details of complex models. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the present invention provides an intelligent multi-resolution feature-optimized three-dimensional reconstruction method and system, which uses curvature as a basis to automatically identify the feature area of ​​t...
