Abstract: An example method for removing an unwanted point from a point cloud is provided. The method includes grouping points of the point cloud based on a frequency of occurrence of the points relative to a vertical axis defined for an environment. The method further includes identifying a first set of points corresponding to an upper boundary of the environment and identifying a second set of points corresponding to a lower boundary of the environment. The method further includes generating a revised point cloud. The revised point cloud excludes points above the upper boundary and points below the lower boundary.

Abstract: An example method for feature extraction includes receiving a selection of a point from a plurality of points, the plurality of points representing an object. The method further includes identifying a feature of interest for the object based at least in part on the point. The method further includes performing edge extraction on the feature of interest. The method further includes performing pre-processing on results of the edge extraction. The method further includes classifying the feature of interest based at least in part on results of the pre-processing. The method further includes constructing, based at least in part on results of the classifying, a geometric primitive or mathematical function that has a best fit to a set of points from the plurality of points associated with the feature of interest. The method further includes generating a graphical representation of the feature of interest using the geometric primitive or mathematical function.
