Abstract

User interface systems and methods for roof estimation are described. Example embodiments include a roof estimation system that provides a user interface configured to facilitate roof model generation based on one or more aerial images of a building roof. In one embodiment, roof model generation includes image registration, image lean correction, roof section pitch determination, wire frame model construction, and/or roof model review. The described user interface provides user interface controls that may be manipulated by an operator to perform at least some of the functions of roof model generation. In one embodiment, the user interface provides user interface controls that facilitate the determination of pitch of one or more sections of a building roof. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

Claims

1. A computer-implemented method, comprising:

displaying an aerial image of a building having a roof comprising a plurality of planar roof sections that each have a corresponding pitch;

displaying an interactive user interface control configured to be manipulated by an operator to align with a slope of a first planar roof section of the plurality of planar roof sections in order to specify pitch of the first planar roof section, wherein the interactive user interface control is overlaid on the aerial image of the building having the roof;

receiving, based on alignment of the displayed interactive user interface control, an indication of the pitch of the first planar roof section of the plurality of planar roof sections of the roof of the building;

modifying a model of the roof based on the received indication of the pitch of the first planar roof section; and

generating and output a roof estimate report using a report generation engine, wherein the roof estimate report includes numerical values annotated with corresponding slope, pitches, total area of the roof, identification and measurement of ridges and valleys of the roof, different elevation views rendered from a 3D model of the roof, and lengths of corresponding roof section for each line segment of edges of a plurality of planar roof sections of the roof, wherein the generated roof estimate report is provided for repair or construction of a corresponding roof structure of the building.

2. The method of claim 1, wherein the interactive user interface control is configured to be manipulated by the operator to lie atop the first planar roof section and an adjacent second planar roof section of the plurality of planar roof sections.

3. The method of claim 1, wherein the interactive user interface control is configured to be manipulated by the operator to adjust the shape of the user interface control.

4. The method of claim 3, wherein the interactive user interface control is configured to be manipulated by the operator to adjust the shape of the user interface control, such that the user interface control aligns with the roof.

5. The method of claim 1, further comprising displaying the model of the roof.

7. The method of claim 1, further comprising modifying the model of the roof based on the user interface control.

8. The method of claim 1, wherein the interactive user interface control is adjustable to specify pitch of one or more of the plurality of planar roof sections.

9. The method of claim 1, further comprising transmitting roof measurement information based on the modified model of the roof, the roof measurement information including a measure of the pitch of the first planar roof section.

10. The method of claim 1, wherein modifying the model of the roof includes associating the indicated pitch with a portion of the model of the roof that corresponds to the first planar roof section of the roof of the building.

11. The method of claim 1, further comprising displaying a wireframe rendering of the modified model superimposed on the aerial image of the building.

12. The method of claim 11, wherein displaying the wireframe rendering occurs in response to the receiving of the indicated pitch.

13. The method of claim 1 wherein modifying the model of the roof includes modifying a three-dimensional model of the roof.
