Claim 16:
17. A method of detecting railroad track misalignments via a railroad track misalignment system, comprising:
receiving, via a first imaging sensor coupled to a rail vehicle, a first rail view of a first section of a first rail;
generating first imaging data related to the first rail via the first imaging sensor;
receiving, via a second imaging sensor coupled to the rail vehicle, a second rail view of a second section of the first rail;
generating second imaging data related to the first rail via the second imaging sensor; and
generating inertial sensor data, via an inertial sensor, to provide an estimation of a railcar's velocity, heading, and orientation; and
comparing, via an edge processor, the first and second or a third and fourth imaging data to determine whether any differences between the first and the second imaging data or the third and the fourth imaging data exceed an adaptive anomaly threshold, to detect railroad track misalignments.
