Definitions

  • This invention is in the field of building size estimation, and in particular, building floor area estimation.
  • Building floor area is used throughout the construction, real estate, insurance and finance industries. For example, the square footage measurement of a building is used as a main factor in quickly determining the market value of real estate, estimating costs of materials to repair or replace flooring and make other improvements or modifications to the entire building. Thus, accurate floor area measurements are instrumental in these calculations. Current methods of measuring floor area often involve a person having to visit the building and manually measure particular dimensions within the building, or by referring to original plans or blueprints of the building. Manually measuring the dimensions for verification of building floor area is costly and original plans for the building may be unavailable or out of date. Therefore, accurate methods for estimating and verifying floor area that avoid these drawbacks are desirable.
  • a floor area measurement system receives a first and a second aerial image of the building, each of the aerial images providing a different view of the roof of the building.
  • the system correlates the first aerial image with the second aerial image to generate a three-dimensional model of the roof that includes a plurality of planar roof sections that each have a corresponding slope, area, and edges.
  • An adjusted roof model is generated by adjusting a slope of the planar roof sections in the three dimensional model of the roof to substantially zero.
  • This may be performed in a variety of manners, including, for example, removing particular roof features from the model that would not be present in a flat roof with no slope (i.e., "fusing" individual planar roof sections in the model into one flat roof section), such as by removing ridge lines or other features distinguishing individual planar roof sections.
  • This may be performed instead of or in addition to adjusting a slope parameter or variable of each roof section within the roof model to zero.
  • this step may be performed with just one initial aerial image of the building showing a substantially orthogonal view of the building since roof pitch need not be determined and can be assumed to be zero.
  • the system generates the estimated floor area measurement of the building based on the calculated estimated total roof area of the roof after the roof model has been adjusted. This is based on a correlation between the size of the building roof and the size of the building. Typically, the floor area of a single full floor of the building is roughly the size of the roof of the building if the roof were flat with no slope (i.e., virtually turning the roof into another floor). With additional adjustments to the roof area measurements to account for multiple floors, roof overhang, wall width, internal building features such as walls and staircases, and/or obstructed views of the building in the aerial image(s), etc., an even more accurate floor area estimation is generated.

  • the roof area measurement estimation system may be a system integrated with a roof estimation system or other system that provides roof measurements.
  • the roof area may be a system integrated with a roof estimation system or other system that provides roof measurements.

  • the process generates roof edge measurements based on initial roof edge measurements included in the received roof measurements, assuming each section of the roof has no slope regardless of an actual slope of each section of the roof. For example, if the two edges of the gable of a pitched roof are 20 feet and the gable has a pitch angle of 90 degrees, then instead of two edges of 20 feet, the process generates a single roof edge of sqrt(800) ⁇ 28.3 feet.

Abstract

L'invention concerne un système qui génère une mesure de superficie d'étage estimée d'un immeuble sur la base de la surface totale du toit estimée calculée de l'immeuble. Ceci est basé sur la corrélation entre la taille du toit de l'immeuble et la taille de l'immeuble. Généralement, la surface de l'étage d'un seul étage complet d'immeuble est approximativement de la taille du toit de l'immeuble si le toit est plat sans inclinaison (c'est-à-dire, à transformer virtuellement le toit en un autre étage pour générer la surface d'étage estimée). Avec des réglages supplémentaires par rapport aux mesures de superficie pour prendre en compte les multiples étages, l'avant-toit, la largeur des parois, les caractéristiques intérieures de l'immeuble et/ou les vues obstruées de l'immeuble dans la/les image(s) aérienne(s), etc., une estimation de surface d'étage encore plus précise peut être générée.
