Abstract
Abstract An integrated system generates a model of a three-dimensional object. A scanning laser device scans the three-dimensional object and generates a point cloud. The points of the point cloud each indicate a location of a corresponding point on a surface of the object. A first model is generated, responsive to the point cloud, that generates a first model representing constituent geometric shapes of the object. A data file is generated, responsive to the first model, that can be inputted to a computer-aided design system.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A method for fitting a point cloud representing a corner, comprising: determining a fit of three planes to the points of the point cloud and creating the planes for a model; determining the three lines at the intersection of pairs of planes and creating the lines for the model; determining the vertex point at the intersection of the three planes and creating a vertex point for the model; and wherein the determining said fit of three planes, includes: using a first fitting algorithm to determine a first plane of the corner which corresponds to a first set of points of the group of points; using a second fitting algorithm to determine a second plane of the corner which corresponds to a second set of points of the group of points; and using a third fitting algorithm to determine a third plane of the corner which corresponds to a third set of points of the group of points.
Claim 2
Independent Claim

Claim 3
Independent Claim
113 words
A method for fitting a point cloud representing a corner, comprising: partitioning a group of points specified by a user into a first set of points, wherein the first set of points corresponds to a first plane that forms a first part of the corner; partitioning the group of points specified by said user into a second set of points, wherein the second set of points corresponds to a second plane that forms second part of the corner; and partitioning the group of points specified by said user into a third set of points wherein the third set of point correspond to a third plane that forms a third part of the corner.
Claim 4
Independent Claim
113 words
A method for fitting a point cloud representing a corner, comprising: partitioning a group of points specified by a user into a first set of points, wherein the first set of points corresponds to a first plane that forms a first part of the corner; partitioning the group of points specified by said user into a second set of points, wherein the second set of points corresponds to a second plane that forms second part of the corner; and partitioning the group of points specified by said user into a third set of points wherein the third set of point correspond to a third plane that forms a third part of the corner.
Claim 5
Dependent Claim
87 words
The method of claim 2 , further comprising: using a first fitting algorithm to determine the first plane of the corner which corresponds to the first set of points of the group of points; using a second fitting algorithm to determine the second plane of the corner which corresponds to the second set of points of the group of points; and using a third fitting algorithm to determine the third plane of the corner which corresponds to the third set of points of the group of points.
