IDENTIFYING OBJECTS USING A 3D SCANNING DEVICE, IMAGES, AND 3D MODELS

摘要

This application is drawn to methods for identifying three-dimensional objects. Methods disclosed herein may include converting 3D model data to a set of simple surfaces, and generating searchable parameters from the image data and/or the simple surfaces. The searchable parameters may be stored in a database as metadata. A searcher may construct a search query by providing 3D model data from which search parameters and features may be extracted and used to formulate a query.

1. A method for identifying three-dimensional objects, comprising:
providing a set of three-dimensional model data of a subject; converting the set of three-dimensional model data to a set of continuous simple surfaces using a fitting method selected from one or more of a random sample consensus (RANSAC) method, an iterative closest point method, a least squares method, a Newtonian method, a quasi-Newtonian method, or an expectation-maximization method, wherein a simple surface comprises a planar surface, a cylindrical surface, a spherical surface, a sinusoidal surface, or a conic surface; generating searchable parameters from features of the set of continuous simple surfaces; storing the searchable parameters in a database as metadata of the three-dimensional model data; providing a search interface adapted to receive three-dimensional model data as input for a search query, the search interface being adapted to formulate a search query from the input; and matching the search query to one or more records of the database and retrieving said records.
