SEMANTIC LABELING OF NEGATIVE SPACES - A simplified explanation of the abstract

• This abstract for appeared for patent application number 18209582 Titled 'SEMANTIC LABELING OF NEGATIVE SPACES'

Simplified Explanation

This abstract describes a method for defining a negative space in a three-dimensional scene model. The method involves obtaining a three-dimensional model of a physical environment and identifying a subspace within that model that contains fewer points than a specified threshold. The method then determines a semantic label for this subspace and generates a characterization vector that includes information about the spatial extent of the subspace and its semantic label.

Original Abstract Submitted

In one implementation, a method of defining a negative space in a three-dimensional scene model is performed at a device including a processor and non-transitory memory. The method includes obtaining a three-dimensional scene model of a physical environment including a plurality of points, wherein each of the plurality of points is associated with a set of coordinates in a three-dimensional space. The method includes defining a subspace in the three-dimensional space with less than a threshold number of the plurality of points. The method includes determining a semantic label for the subspace. The method includes generating a characterization vector of the subspace, wherein the characterization vector includes the spatial extent of the subspace and the semantic label.
