Abstract:
Disclosed is a position detection system capable of detecting the position of a line-shaped object. From among two connected lines (E1E2 and E1′E2′) created by connecting opposed intersecting points among four interesting points (E1, E2, E1′, and E2′), a position detection unit (12) treats the one connected line (E1E2) with a length closer to the overall length of a rod (ST) as the position of the rod (ST) that overlaps a coordinate map region (MA).
