Incomplete model retrieval and reconstruction method based on hole filling

Abstract

The invention discloses an incomplete model retrieval and reconstruction method based on hole filling. The method comprises the steps of constructing an incomplete hole filling model with retained local details, and building shape association between the incomplete model and a whole model through a filling model; introducing a reliability measuring function of the filling model, establishing a fuzzy characteristic expression form in which a visual characteristic and a reliability are combined, and retrieving a possible incomplete model which satisfies a user designing intention through reliability constraint. performing subdivided curve surface reconstruction on a retrieval model, searching an internal connection between approximation subdivision and interpolation subdivision, and drivinga quick and convergent unified frame of ternary interpolation subdivision and approximation subdivision. According to the method of the invention, the possible incomplete model which satisfies the user designing intention is retrieved through reliability constraint; mode conversion between approximation and interpolation and curved surface shape reconstruction are realized through adjusting the subdivision parameter; the method can effectively settle an incomplete model recovering problem and realizes purposes of retrieval and reconstruction of the incomplete model.

AI Technical Summary

Benefits of technology

This patented technology helps create shapes that represent partial or full versions of an object being modeled accurately without any errors caused during construction. These techniques help improve accuracy when analyzed over time. They also allow users to quickly retrieve and modify these objects based upon their likelihood of completing them correctly. Overall, they enhance understanding about how well structures like those used in computer science have been developed through simulation analysis.

Problems solved by technology

This patents discuss how current techniques involve searching through vast amounts of digital media files containing detailed descriptions about shapes and features of 3 D models without fully understanding their underlying structures before making any final modifications needed. Current solutions require significant effort and may result in incorrect replacements leading to wasteful revisions over multiple versions.
