3D segmentation method for stl triangular mesh model

ActiveCN102298795A3D Segmentation RealizationAdaptable3D modellingVertical planeAlgorithm
The invention discloses a three-dimensional segmenting method for an STL (Standard Template Library) triangular network model in rapid molding process. The three-dimensional segmenting method comprises the following steps of: firstly, reading the STL triangular network model from an STL file into an internal storage, and establishing complete topological information of a surface patch, a side and a peak in the STL model based on an improved wing-edge structure; secondly, repeatedly searching through information in the internal storage to obtain a highest position surface patch serving as a seed surface patch in an original STL model, and searching an adjacent surface patch having the same normal vector Z-axis component symbol as the seed surface patch with a boundary expansion method on the basis to obtain a plurality of sub-STL models having the same normal vector Z-axis component symbol; and lastly, checking the boundary of each sub-STL model, recognizing and extracting covered boundary lines, and segmenting the sub-STL model by using a vertical plane defined by the covered boundary lines to further generate non-interfered sub-STL models. By adopting the three-dimensional segmenting method, three-dimensional segmentation of the STL triangular network model can be realized effectively; and moreover, the triangular network model has the advantages of high adaptability, high efficiency and low resource consumption.

Image inpainting method based on structure and texture hierarchical prediction

The invention discloses an image inpainting method based on structure and texture hierarchical prediction. The method comprises a network model training part and an image inpainting part. The networkmodel training part comprises the steps of pre-processing a training data set, extracting an edge structure chart, constructing and training a structure completion network N1, and constructing and training a texture conversion network N2; and the image inpainting part comprises the steps of inputting a tested image to be repaired and pre-processing, extracting the edge structure chart, using the structure completion network N1 to generate an edge structure of a defect area, using the texture conversion network N2 to generate image content of the defect area, and enabling the generated image content of the defect area to fill the image to be repaired. The method is capable of decomposing a problem of the image inpainting to problems of the structure and texture hierarchical prediction, automatically generating a defect structure, and using a repaired structure edge graph to constrain a texture generating process, thereby effectively avoiding the texture confusion and the shape distortion, and greatly improving the repairing capacity in allusion to a natural image large area defect problem.
