Abstract: A method for autonomously navigating an aerial vehicle along a railroad track includes obtaining, from one or more cameras coupled to the aerial vehicle, image data reproducible as an image of a portion of the railroad track, identifying, based at least in part on the image data, a first rail and a second rail of the portion of the railroad track, determining, based at least in part on the identified first and second rails of the portion of the railroad track, a centerline of the portion of the railroad track, and generating, based at least in part on the determined centerline, flight instructions to cause the aerial vehicle to move relative to the railroad track.

Abstract: A method for inspecting a railroad track include detecting, using one or more sensors of an inspection system, movement of a transport device along the railroad track, responsive to the detecting, automatically actuating one or more cameras of the inspection system, receiving, from at least one of the one or more cameras, first image data reproducible as a first image of a first portion of the railroad track, analyzing the first image data to identify the presence or absence of one or more features of interest on the first portion of the railroad track; determining a first location of the transport device, and associating the first location of the transport device with the first image data.
