Trolley wire wear measuring device using binary operated images |
摘要 |
A trolley wire wear measuring device includes a processor configured to obtain a pair of line sensor images in which luminance signals of scanning lines are arranged; a differential processor configured to perform a differential process to create a line sensor image; a binary operation processor configured to perform a binary operation process on the line sensor image obtained by the differential process to create a binary operated image in which a worn portion of the trolley wire is emphasized; an edge detector configured to detect edges of both sides of the worn portion in the binary operated image; and a worn portion width calculator configured to calculate a point-to-point distance of the both side edges as a whole width of the worn portion of the trolley wire in the binary operated image and determine a worn portion width of the trolley wire using this whole width. |
