Multi-dimensional model dimensioning and scale error correction
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.
1. A method of correcting scale for a multi-dimensional building model comprises:
identifying an architectural element located on a plane of the multi-dimensional building model, wherein the identified architectural element includes at least one roof element including one or more of: shingles, gables, eaves, dormers, and gutters;
determining one or more positions of the identified architectural element;
selecting a known relative position of a known similar architectural element, wherein the known relative position of a known similar architectural element includes construction industry standards of a predetermined architectural standard position of a known similar architectural element relative to a building plane;
comparing the determined one or more positions of the identified architectural element to the selected known relative positions of the known similar architectural element to determine an error in position of the identified architectural element;
determining a scale for the plane of the identified architectural element based on the error in position of the identified architectural element; and
scaling one or more planes of the multi-dimensional building model according to the determined scale.
2. 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.
3. The method of claim 1 further comprises reconstructing and rescaling the multi-dimensional building model based on the determined scale.
4. The method of claim 1 , wherein the multi-dimensional building model includes two or more identified architectural elements.
5. 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.
6. The method of claim 1 , wherein the multi-dimensional building model includes imagery rectified and correlated to vertices of geometric planes or polygons of the multi-dimensional building model.
7. A system for rescaling a multi-dimensional building model comprising:
a multi-dimensional building model database operable to store a multi-dimensional building model; and
a processor communicatively coupled to the multi-dimensional building model database and operable to:
identify an architectural element located on a plane of the multi-dimensional building model;
determine one or more positions of the identified architectural element;
select a known relative position of a known similar architectural element, wherein the known relative position of a known similar architectural element includes construction industry standards of a predetermined architectural standard position of a known similar architectural element relative to a building plane, wherein the identified architectural element is at least a first side of a building gable and the selected known relative position of a known similar architectural element includes supporting a first plane identified as an exterior wall at a known distance from an edge of the at least a first side of a building gable;
compare the determined one or more positions of the identified architectural element to the selected known relative positions of the known similar architectural element to determine an error in position of the identified architectural element;
determine a scale for the plane of the identified architectural element based on the error in position of the identified architectural element; and
scale one or more planes of the multi-dimensional building model according to the determined scale.
8. The system of claim 7 further comprises the identified architectural element also including a second side of the building gable and the selected known relative position of a known similar architectural element includes a second plane identified as an exterior wall that is symmetrically positioned with respect to the first plane and a center point of the building gable.
9. A mobile device for a multi-dimensional building model comprising:
a display to display a multi-dimensional building model; and
a processor communicatively coupled to a multi-dimensional building model database and operable to:
identify an architectural element located on a plane of the multi-dimensional building model;
determine one or more positions of the identified architectural element;
select a known relative position of a known similar architectural element, wherein the known relative position of a known similar architectural element includes construction industry standards of a predetermined architectural standard position of a known similar architectural element relative to a building plane, wherein the identified architectural element is a downspout and the selected known relative position of a known similar architectural element includes a position adjacent to at least one plane in the multi-dimensional building model comprising an exterior wall;
compare the determined one or more positions of the identified architectural element to the selected known relative positions of the known similar architectural element to determine an error in position of the identified architectural element;
