System and method for construction estimation using aerial images

摘要

A system and method for construction estimation using aerial images is provided. The system receives at least one aerial image of a building. An estimation engine processes the aerial image at a plurality of angles to automatically identify a plurality (e.g., perimeter and interior) lines in the image corresponding to a plurality of features of a roof the building. The estimation engine allows users to generate two-dimensional and three-dimensional models of the roof by automatically delineating various roof features, and generates a report including information about the roof of the building.

1. A system for construction estimation, comprising:
a computer system for receiving at least one aerial image of a building; and an estimation engine in said computer system for processing the aerial image to estimate one or more features relating to a roof of the building, the estimation engine:
processing the aerial image with a filter to compute a likelihood for each point in the aerial image indicating whether the point represents a roof line;scanning the aerial image at a first angle to obtain first image intensity data;rotating the aerial image to a second angle different from the first angle;scanning the aerial image at the second angle to obtain second image intensity data;processing the first and second image intensity data to automatically identify a plurality of lines in the aerial image corresponding to one or more features of the roof;constructing a two-dimensional model of the roof using the plurality of lines identified in the aerial image; andmanipulating the two-dimensional model into a three-dimensional model of the roof by displaying the two-dimensional model superimposed onto an oblique image of the roof and allowing the user to click and drag perimeter and interior points of the two-dimensional model to corresponding points on the oblique image of the roof.
