  • Publication number: 20230100515
    Abstract: A system, apparatus, computer program product, and method use a convolutional neural network to auto-determine a first floor height (FFH) and a FFH elevation (FFE) of a building. The FFH, and FFE of the building are determined with respect to the terrain or surface of the parcel of land on which the building is located. In turn, by knowing the FFH and/or FFE of the building on the parcel, it is possible to use that information while performing a flood risk assessment to a property without requiring a personal inspection of the parcel by a human.

  • Patent number: 11612960
    Abstract: Laser additive manufacturing and a method for preparing thin-walled preforms by laser metal deposition and follow-up rolling. This can solve the problems that when the existing laser metal deposition technology prepares the thin-walled preforms, the limit width size of a molten pool at high power affects the forming wall thickness of the preforms so that it is difficult to prepare preforms with wall thickness less than 2 mm, and the problems of poor surface quality and low accuracy of preforms due to convex and concave peaks caused by the interlayer overlapping, but also can solve the problems that a laser beam with a preset trajectory cannot act on the end surfaces of the preforms due to preform deformation caused by residual stress in a printing process so that the preforms cannot be continuously formed.
