1. A computer-implemented method of inspecting a structure, the method comprising:
- deploying a three-dimensional (3D) data collection system including one or more 3D scanners;
physically tethering via a tether the 3D data collection system to a device on the ground;
transmitting, by a laser projector of the one or more 3D scanners, a plurality of laser pulses directed toward a surface of a structure;
detecting, at a laser light sensor of the one or more 3D scanners, the plurality of laser pulses after the plurality of laser pulses have reflected off of the surface of the structure;
generating, by one or more processors, a 3D model of the surface of the structure based on the detected plurality of laser pulses;
automatically analyzing, by the one or more processors, the 3D model of the surface of the structure to identify one or more features of the surface of the structure;
generating, by the one or more processors, an estimate of a condition of the surface of the structure based on the identified one or more features; and
storing to memory the generated estimate of the condition of the surface.

Abstract
In a computer-implemented method and system for capturing the condition of a structure, the structure is scanned with a three-dimensional (3D) scanner. The 3D scanner generates 3D data. A point cloud or 3D model is constructed from the 3D data. The point cloud or 3D model is then analyzed to determine the condition of the structure.
