US Patent 11598631 Determining depth of buried assets

Techniques for determining a depth of a buried asset are provided. A first point on an AR model of the buried asset is identified. The first point is where a depth of the buried asset is to be determined. An AR device is used to determine coordinates of a second point on a surface corresponding to the first point on the AR model. Coordinates of a third point on the buried asset corresponding to the first point on the AR model are determined. The depth of the buried asset is determined based on the coordinates of the second point on the surface and coordinates of the third point on the buried asset.
