Abstract
The present application involves a railroad track asset surveying system comprising an image capture sensor, a location determining system, and an image processor. The image capture sensor is mounted to a railroad vehicle. The location determining system holds images captured by the image capture sensor. The image processor includes an asset classifier and an asset status analyser. The asset classifier detects an asset in one or more captured images and classifies the detected asset by assigning an asset type to the detected asset from a predetermined list of asset types according to one or more features in the captured image. The asset status analyser identifies an asset status characteristic and compares the identified status characteristic to a predetermined asset characteristic so as to evaluate a deviation therefrom.

41. A railroad track asset surveying system comprising:
-
an image capture sensor mounted on a railroad vehicle; a location determining system for images captured by the sensor; and an image processor comprising; an asset classifier for 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 in the captured image; and an asset status analyser for identifying an asset status characteristic and comparing the identified status characteristic to a predetermined asset characteristic so as to evaluate a deviation therefrom. - View Dependent Claims (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. A railroad track asset surveying 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 and comparing the identified status characteristic to a predetermined asset characteristic so as to evaluate a deviation therefrom.

81. 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 (82, 83, 84, 85)
