Patent Images
1. A system for computing and displaying a roundness error of an object, comprising:
- a colors specifying module configured for specifying a plurality of different colors, wherein each of the colors represents a specific error range of points;
a points receiving module configured for receiving a point cloud of the object;
a circle fitting module configured for fitting a circle based on points in the point cloud using a least square method;
a distance computing module configured for computing an error of each point in the point cloud based on the circle;
a points colorizing module configured for colorizing the points in the point cloud according to the errors of the points and the specified colors;
an outputting module configured for generating a graphic roundness error analysis report comprising the specified colors, the circle, the colorized points, and outputting the graphic roundness error analysis report; and
at least one processor that executes the colors specifying module, the points receiving module, the circle fitting module, the distance computing module, the points colorizing module, and the outputting module.

Abstract
A method and system for computing and displaying a roundness error of an object specifies different colors that respectively represents an error range of points. The method and system receives a point cloud of the object and fits a circle based on the point cloud. The method and system computes an error of each point in the point cloud by computing a distance between the each point and the circle, colorizes the points in the point cloud according to the errors and the specified colors, and generates and outputting a graphic roundness error analysis report.
