摘要： PROBLEM TO BE SOLVED: To perform reverse modeling by following a procedure in which an original product designer has designed a product by a three dimensional CAD program by using mesh data as a feature.
SOLUTION: This reverse modeling method includes the steps of: detecting optional mesh data, setting the mesh data as a feature, and establishing a reference coordinate system of set mesh data; establishing a work plane on which a sketch of the set mesh data can be projected; projecting section data of the mesh data on a work plane for sketch production; dividing data projected on the work plane for sketch production into feature segments depending upon curvature distributions, and producing divided segments as sketch data; and producing a three dimensional feature from the sketch data which corresponds to a shape of the mesh data.

摘要： A system and a method of guiding a real-time inspection using a 3D scanner are provided. The system and the method of guiding a real-time inspection using a 3D scanner allow an operator to perform an accurate and swift inspection of an object to be measured so as to meet a designer's design intentions. For that purpose, 3D shape information of an object to be measured is detected using a scanner and shape information and inspection guide information of the object stored in a data storage unit, and inspection information of the object for judging the validity of the measurement information detected from the scanner is checked through a display unit. After that, the scanner is operated to compare the measurement information detected by the scanner with the inspection information so as to judge the validity of the measurement. Therefore, an operator can accurately understand a designer's intentions for inspection to perform measurement.

摘要： A mechanism for automatically calculating loft surfaces from raw 3D scan data represented as a mesh or point cloud model is discussed. Users enter parameters related to the loft surface calculation via a provided user interface. User input and/or programmatically calculated parameters may include U-V direction, guide curve identification, and the amount of allowable deviation error between the calculated loft surface and the 3D scan data. Profile curves meeting the given parameters are then generated and a loft surface is calculated using the generated profile curves for a selected region. The user may select geometrically separated regions in order to create a single loft surface that connects the separate regions.

摘要： An automated mechanism that identifies and defines a global coordinate system that is most appropriate for a collection of raw 3D scan data used to form a mesh model is discussed. More specifically, a coordinate system is identified that is able to minimize the total sum of deviation error while also minimizing the peak error for raw 3D scan data. The present invention searches for appropriate coordinate systems from raw 3D scan data in a fully automated way. Multiple coordinate systems in order of likelihood of leading to minimal global deviation error are identified and presented to a user. End users are also allowed to edit suggested coordinate system parameters interactively prior to the alignment of the 3D scan data being transformed based on a selected coordinate system.

摘要： A mechanism for enabling a user to treat 3D scan data model regions as surface bodies so as to eliminate the need to convert model regions to parametric surfaces as a prerequisite to performing part body modeling operations is discussed. During CAD re-modeling raw 3D scan data is imported. The present invention allows a user to use a region directly as an input argument for a part body modeling operation as long as a sheet body (surface body) is applicable as a modeling input argument. Additionally, if any regions used in the body modeling are modified by the user, surfaces which have been generated from fitting regions are also recalculated and the body model is updated automatically. The region modification can happen when the user includes more scan data in the region, excludes scan data from the region, smoothes geometry, or uses other editing functions.

摘要： The method involves detecting optional model data e.g. scanned data, stored in a data storage unit (50) and setting a working plane for detecting two-dimensional sectional data of the model data. Two-dimensional projected sectional data of the model data is determined. The two-dimensional projected sectional data is divided into characteristic segments based on curvature distribution. An auxiliary condition and numeric information are determined in consistence with a connection of the divided characteristic segments of the projected sectional data, and providing two-dimensional picture data.
