Abstract

A system and method are provided for identifying scale, scale error, or improper positioning during construction or reconstruction of a multi-dimensional (e.g., 3D) building model using known architectural dimensions. The system identifies architectural elements that have known architectural standard positions relative to planes within the multi-dimensional model. Dimensional measurements of architectural elements in the multi-dimensional model (poorly scaled) are compared with known architectural standard dimensions, with or without scale error, to properly scale, rescale or position one or more planes within the multi-dimensional building model.

Claims

1. A method of correcting a multi-dimensional building model comprises:

automatically identifying an architectural element located within the multi-dimensional building model, wherein the multi-dimensional building model includes a plurality of facades, wherein each faç

ade of the plurality of facades has been previously rectified and correlated to vertices of geometric planes that make up at least a portion of the multi-dimensional building model and wherein the architectural element is distinct from and automatically identified separately from the faç

ade;

determining a position of the identified architectural element within the multi-dimensional building model;

identifying at least one plane within the multi-dimensional building model with a predetermined known relationship to the identified architectural element;

determining an error in position of the identified at least one plane based on a comparison of the predetermined known relationship to the identified architectural element within the multi-dimensional building model; and

moving a first position of the identified at least one plane to a second position within the multi-dimensional building model based on the determined error in position.

2. The method of claim 1, wherein the identified architectural element includes a roof overhang and the at least one plane includes at least an exterior wall placement relative to an edge of the roof overhang.

3. The method of claim 1, wherein the identified architectural element is a downspout, the at least one plane includes an exterior wall, and the predetermined known relationship includes a position adjacent to the exterior wall.

4. The method of claim 3, the position adjacent to the exterior wall is adjusted for a predetermined known gap between the downspout and the exterior wall.

5. The method of claim 1, wherein the predetermined known relationship between the identified architectural element and one or more associated planes in the multi-dimensional building model is based on geometrically calculating a relative measurement relationship.

6. The method of claim 5, wherein the relative measurement relationship is symmetry.

7. The method of claim 5, wherein the relative measurement relationship is symmetry, the identified architectural element is a gable, the at least one plane in the multi-dimensional building model includes two or more walls supporting the gable, and the predetermined known relationship to the identified architectural element includes wall positions equidistant from a center of the gable.

8. The method of claim 1, wherein the multi-dimensional building model includes any of:

a two-dimensional (2D) building, a three-dimensional (3D) building or a building interior.

9. The method of claim 1 further comprises reconstructing the multi-dimensional building model based on the second position.

10. The method of claim 1, wherein the identified architectural element includes roof features including any of:

shingles, gables, eaves, dormers, gutters, chimney structures, pipe stacks, turbine vents, skylights, dormers, solar panels, fans, gutters, fascia boards, or rakes.

11. The method of claim 1, wherein the multi-dimensional building model includes two or more identified architectural elements.

12. The method of claim 1, wherein the error in position includes one or more dimensional errors associated with any of:

width, height, length, depth, radius, diameter, circumference, or perimeter.

13. A system for correcting a multi-dimensional building model comprising:

a multi-dimensional building model database operable to store a multi-dimensional building model, wherein the multi-dimensional building model includes a plurality of facades and wherein each faç

ade of the plurality of facades has been previously rectified and correlated to vertices of geometric planes that make up at least a portion of the multi-dimensional building model; and

a processor communicatively coupled to the multi-dimensional building model database and operable to;

automatically identify an architectural element located within the multi-dimensional building model, wherein the architectural element is distinct from and automatically identified separately from the plurality of faç

ades;

determine a position of the identified architectural element within the multi-dimensional building model;

identify at least one plane within the multi-dimensional building model with a predetermined known relationship to the identified architectural element;

determine an error in position of the identified at least one plane based on a comparison of the predetermined known relationship to the identified architectural element within the multi-dimensional building model; and

move a first position of the identified at least one plane to a second position within the multi-dimensional building model based on the determined error in position.

14. The system of claim 13, wherein the architectural element includes roof features including any of:

shingles, gables, eaves, dormers, gutters, chimney structures, pipe stacks, turbine vents, skylights, dormers, solar panels, fans, gutters, fascia boards, or rakes.

15. The system of claim 13, wherein the error in position include one or more dimensional errors associated with any of:

width, height, length, depth, radius, diameter, circumference, or perimeter.

16. A method of correcting a multi-dimensional building model comprises:

identifying an architectural element located on or near a faç

ade of the multi-dimensional building model, wherein the multi-dimensional building model includes a plurality of facades, wherein each faç

ade of the plurality of facades has been previously rectified and correlated to vertices of geometric planes that make up at least a portion of the multi-dimensional building model and wherein the architectural element is distinct from and identified separately from the facade;

determining one or more positions of the identified architectural element;

automatically selecting known relative positions of known similar architectural elements based on known relationships between the identified architectural element and one or more associated planes in the multi-dimensional building model;

determining a corrected position for the identified architectural element based on an error in position of the identified architectural element compared to the relative positions of known similar architectural elements; and

correcting positioning of the identified architectural element for one or more planes of the multi-dimensional building model according to the error in position of the identified architectural element.

17. The method of claim 16, wherein the plane includes an exterior wall, the identified architectural element is a downspout, and the known relationships include a position adjacent to the exterior wall.

18. The method of claim 17, wherein the position adjacent to the exterior wall is adjusted for a predetermined known gap between the downspout and the exterior wall.

19. The method of claim 16, wherein the identified architectural element is at least a first side of a gable and the known relationships include supporting a first plane identified as an exterior wall at a known distance from an edge of the gable.

20. The method of claim 19, wherein the identified architectural element is a second side of the gable and the known relationships include a second plane identified as an exterior wall that is symmetrically positioned with respect to the first plane and a center point of the gable.
