Abstract: Systems and techniques for detecting and recognizing a railcar identifier are described herein. An image of a railcar can be captured by an image sensor and provided to processing circuitry of a controller. A bounded portion of the image corresponding to the railcar identifier can be identified and a character recognition process can be performed to identify respective values for characters of the railcar identifier. A check digit can be computed using the identified values to validate the railcar identifier. In some examples, the bounded portion of the image can be automatically adjusted when the check digit fails to validate the railcar identifier.

Abstract: A method can include receiving a first railcar data set from a first image capture device. The first railcar data set can include a first image of a portion of a first railcar, which can include a representation of a first railcar identifier. Receiving a second railcar data set from a second image capture device. The second railcar data set can include a second image of a portion of an unknown railcar, which can include a representation of a second railcar identifier. The method can include using the representation of the first railcar identifier, identifying one or more characters in the first railcar identifier, and using the representation of the second railcar identifier, identifying one or more characters in the second railcar identifier. Determining a railcar identifier recognition result for the first railcar based on a correspondence between the identified characters in the first and second railcar identifiers.

Abstract: Systems and techniques for detecting a railcar identifier are described herein. A method can include receiving railcar image information including at least an image portion that contains, or is likely to contain, a railcar identifier for a first railcar at a data input stage of a railcar identification processor. The method can also include analyzing the railcar image information to identify characters of the railcar identifier for the first railcar at a recognition stage of the railcar identification processor. The analyzing of the railcar image information can include using two or more of a confidence algorithm, a result frequency algorithm, and a per-character algorithm. The method can also include providing a first recognition result with information about the identified characters of the railcar identifier for the first railcar at an output stage of the railcar identification processor.
