Abstract
A mesh model of a 3D space is provided with improved accuracy by refining the locations of edges of objects in the space. The mesh model includes vertices which define surfaces of triangles. Triangles are identified which have two vertices in one plane and another, outlier vertex in another, adjacent plane. A line is fitted to the outlier vertices to define an edge of an object, and the outlier vertices are moved to the line, referred to as a mesh-based line. Texture data from images of the space can be used to further refine the edge. In one approach, gradients in grayscale pixels which correspond the vertices of the mesh-based line are used to define a grayscale-based line. The two line definitions can be combined or otherwise used to provide a final definition of the edge. The object can be measured based on the length and position of the edge.
