OVERHEAD LINE POSITION MEASURING DEVICE AND METHOD

摘要

An overhead line position measuring apparatus which also enables contactless three-dimensional position measurement using an inspection car as to an overhead line other than a contact wire. The overhead line position measuring apparatus includes: first and second three-dimensional measuring devices; first and second cameras; a region of interest setting part for setting at least one region of interest based on angle data and distance data generated by each of the first and second three-dimensional measuring devices; an image processing part for performing image processing on each of first and second image data respectively generated by the first and second cameras to mask the image except for the region of interest, and accumulating the first and second image data into amemory; an overhead line extracting part for extracting an overhead line satisfying a predetermined condition from a two-dimensional image represented by each of the accumulated first and second image data; and an overhead line position calculating part for calculating a position of the overhead line in relation to the railway vehicle based on coordinates of the overhead line extracted by the overhead line extracting part.
