Patent attributes
The present disclosure is directed to a software tool that engages in an image matching technique. In one implementation, the software tool (i) accesses a set of two-dimensional drawings representative of a construction project, (ii) determines multiple candidate pixel regions for each of the two-dimensional drawings, (iii) compares the candidate pixel regions to identify a set of landmark pixel regions that appear in the set of two-dimensional drawings at a threshold rate, (iv) compare a first subset of landmark pixel regions from a first two-dimensional drawing with a second subset of landmark pixel regions from a second two-dimensional drawing to identify matching landmark pixel regions, (v) project the first and second two-dimensional drawings onto a projection space such that a maximum number of the matching landmark pixel regions align, and (vi) determine an extent of similarity between the projected first and second two-dimensional drawings in the projection space.
