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.
