Abstract: The present disclosure describes systems and methods for acquiring structural attributes of a building. One such method comprises acquiring, by one or more cameras of an unmanned aerial vehicle, infrared thermal and visible RGB aerial images of a building; identifying structural components of the building based on an infrared thermal aerial image, wherein a floor structure of the building is identified from a color change in the infrared thermal aerial image between the building and a foundation structure of the building; positioning a bounding box around the floor structure of the building present in the infrared thermal aerial image; and estimating a lowest floor elevation of the building by calculating a lowest floor elevation value based on an amount of image pixels representing a distance between a top of the bounding box and a top of the foundation structure of the building. Other methods and systems are also provided.
