Title:
WIRE MEASUREMENT DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2016/208463
Kind Code:
A1
Abstract:
A wire measurement device is provided with: a first line camera (11) and a second line camera (12) for capturing an image of a wire, the first line camera (11) and the second line camera (12) being disposed at both ends in a railroad-tie direction on a rooftop (10a) of a railroad car (10) and each inclined toward the center in the railroad-tie direction of the railroad car (10); and an image processing unit (9) for detecting sliding surface information and wire information of a wire as a measurement object from an image captured by the first line camera (11) and an image captured by the second line camera (12) and calculating the height and deviation of the wire by performing a mapping of the wire among the captured images using the wire information and the sliding surface information.
