DEVICE FOR MEASURING TROLLEY WIRE WEAR AND DEVIATION BY IMAGE PROCESSING

摘要

Disclosed is a device for measuring trolley wire wear and deviation that is equipped with: a line sensor image creation unit (4a) that creates a line sensor image comprised of chronologically arranged images taken by means of a line sensor (2); a binarization processing unit (4b) that binarizes the line sensor image to create a binarized line sensor image; a trolley wire wear portion edge detection unit (4d) that detects the edges on either side of a wear portion with respect to the binarized line sensor image; a trolley wire center of gravity position detection unit (4e) that detects the position of the center of gravity from the positions of the edges on either side of the wear portion; a trolley wire deviation real coordinates conversion calculation unit (4f) that detects the actual amount of deviation of the trolley wire from the center of gravity position of the trolley wire; and a trolley wire wear portion width calculation unit (4g) that detects the amount of wear of the trolley wire from the positions of the edges on either side of the wear portion; thus enabling trolley wire wear and deviation to be measured with one device.
