Abstract
The present application involves a railroad track inspection system comprising a plurality of track scanning sensors, a data store, and a scan data processor. The data store is used for storing track scan data recorded by the track scanning sensors. The scan data processor is used for automatic analysis of the track scan data upon receipt thereof to detect one or more track components within the scan data from a predetermined list of component types according to one or more features identified in said scan data. The system comprises a common support structure to which the track scanning sensors, the data store and scan data processor are attached, the common support structure having a mounting for attachment of the system to a railway vehicle in use.

34. A railroad track inspection system comprising:
-
a plurality of track scanning sensors; a data store for storing track scan data recorded by the track scanning sensors; and a scan data processor for automatic analysis of said track scan data upon receipt thereof to detect one or more track components within the scan data from a predetermined list of component types according to one or more features identified in said scan data; wherein the system comprises a common support structure to which the track scanning sensors, the data store and scan data processor are attached, the common support structure having a mounting for attachment of the system to a railway vehicle in use. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95)

96. A railroad track inspection method comprising:
-
operating an image capture sensor mounted on a railroad vehicle during motion of the railroad vehicle along a track; determining and logging a location of the image capture sensor for each image captured by the sensor; and automatically processing the captured images upon receipt using one or more computer processor by detecting an asset in one or more captured image and classifying the detected asset by assigning an asset type to the detected asset from a predetermined list of asset types according to one or more feature identified in the captured image, and identifying an asset status characteristic including the recognition and measurement of defects and comparing the identified status characteristic to a predetermined asset characteristic so as to evaluate a deviation therefrom.

97. A data carrier comprising machine readable code of the operation of railroad track asset survey image processor configured to:
-
receive images captured by an image capture sensor mounted on a railroad vehicle during motion of the railroad vehicle along a track; log a geographic location for each image captured by the sensor; process the captured images by detecting an asset in one or more captured image and classifying the detected asset by assigning an asset type to the detected asset from a predetermined list of asset types according to one or more feature identified in the captured image; and identify an asset status characteristic and comparing the identified status characteristic to a predetermined asset characteristic so as to evaluate a deviation therefrom, and output an asset status indication based upon said deviation. - View Dependent Claims (98, 99, 100)
