Abstract
A system for visual inspection of signal lights at a railroad crossing includes a data source comprising a stream of images, the stream of images including images of signal lights at a railroad crossing, an inspection module configured via computer executable instructions to receive the stream of images, detect signal lights and light instances in the stream of images, encode global information relevant to ambient luminosity and return a first feature vector, encode patch information of luminosity of detected signal lights and return a second feature vector, concatenate the first feature vector with the second feature vector and return a concatenated feature vector, and decode the concatenated feature vector and provide status of the signal lights.

A system for visual inspection of signal lights at a railroad crossing, the system comprising:
- a data source comprising a stream of images, the stream of images including images of signal lights at a railroad crossing,
- an inspection module configured via computer executable instructions to receive the stream of images,
- detect signal lights and light instances in the stream of images,
- encode global information relevant to ambient luminosity and return a first feature vector,
- encode patch information of luminosity of detected signal lights and return a second feature vector,
- concatenate the first feature vector with the second feature vector and return a concatenated feature vector, and
- decode the concatenated feature vector and provide status of the signal lights.
A method for visual inspection of signal lights at a railroad crossing, the method comprising, through operation of at least one processor and at least one memory:
- receiving a stream of images,
- detecting signal lights and light instances in the stream of images,
- encoding global information relevant to ambient luminosity and return a first feature vector,
- encoding patch information of luminosity of detected signal lights and return a second feature vector,
- concatenating the first feature vector with the second feature vector and return a concatenated feature vector, and
- decoding the concatenated feature vector and providing status of the signal lights.
