Abstract
Provided is an aerial line extraction system including: an area-of-interest cropping unit that crops a region where a point cloud data of aerial lines is assumed to exist as an area of interest by setting coordinates of utility poles as a reference from a three-dimensional point cloud data of a three-dimensional shape that includes the aerial lines and trees installed in the air via the utility poles; an aerial line candidate extraction unit that extracts a candidate point cloud data of the aerial lines from the three-dimensional point cloud data in the area of interest; and an aerial line model estimation unit that estimates a model of the aerial lines on the basis of the extracted candidate point cloud data of the aerial lines.
