Document Type and Number:
WIPO Patent Application WO/2024/070612
Kind Code:
A1
Abstract:
Provided is a line abnormality detection system which further accurately detects lines in a shorter time. The line abnormality detection system 10 comprises line sensor cameras 11a, 11b, a storage unit, a train line fitting detection unit, a line detection unit, and a line abnormality detection unit. The line sensor cameras 11a, 11b image lines (a suspension line 4, a trolley line 5, a hanger 6) from the vehicle roof 2 of a moving vehicle 1. The line fitting detection unit detects, from image data, a fitting (the hanger 6) accompanying the line. The line detection unit calculates a likelihood indicating the degree at which fittings can be combined in a straight line shape, and detects the lines (the suspension line 4, the trolley line 5) from the image data on the basis of the likelihood. The line abnormality detection unit detects the abnormality of the lines (the suspension line 4, the trolley line 5) from line detection information and the line images.
