Three-dimensional ground feature model repairing method, system and device and storage medium

Abstract

The invention provides a three-dimensional ground object model repairing method, system and device and a storage medium, and relates to three-dimensional grid model deformation, and the method comprises the steps: on a locally deformed three-dimensional ground object model, respectively calibrating a distortion boundary with starting and ending positions and a plurality of distortion triangular patches, according to the starting position, the ending position and the two distorted triangular patches where the starting position and the ending position are located, respectively constructing a model calibration boundary and a segmentation patch where the model calibration boundary is located, and performing triangulation segmentation processing on all the distorted triangular patches according to the junctions of all the distorted triangular patches and the segmentation patch, and after all the segmented distorted triangular patches are calibrated to the model calibration boundary, the segmented patches are deleted, so that the shape of the three-dimensional ground feature model is calibrated based on the original topological structure, the distorted part of local deformation of the three-dimensional ground feature model is really repaired, the repair mode is simplified, and the repair efficiency is improved. The three-dimensional ground object model is prevented from flickering due to the fact that the distortion part is shielded when the three-dimensional ground object model is displayed, and repair efficiency and stability are both considered.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional grid model deformation, and in particular, relates to a method, system, device and storage medium for repairing a three-dimensional object model. Background technique [0002] Relying on the technical development of computing equipment to synthesize images, 3D visual modeling of images can be performed to electronically present real-world objects. It has been extended to many application scenarios such as home theaters, surgical treatments, home theaters, and surveying and mapping. Provide many conveniences. [0003] At present, limited by many factors such as camera conditions, imaging performance, and modeling technology adaptability, it is difficult for some 3D modeling technologies to make the 3D object model truly and accurately reflect the real object in shape, resulting in 3D object model It is prone to distortion. For example, in a 3D city model, the part characterized b...

Problems solved by technology

[0003] At present, limited by many factors such as camera conditions, imaging performance, and modeling technology adaptability, it is difficult for some 3D modeling technologies to make the 3D object model truly and accurately reflect the real object in shape, resulting in 3D object model Prone to distortion, for example, in a 3D city model, parts characterized by horizontal pavements take on an undulating shape, or / and, parts represented by building wall lines or eaves are misaligned, severely degrading 3D visualization

[0004] Too much reliance on human-computer interaction makes the distorted part visually blocked on the 3D object model, and does not really repair the distortion of the 3D object model, and the efficiency is also low
