A method to realizing automatic matching of optical fiber position units using triangulation

This paper fumishes a optical fiber position units auto-match method for LAMOST using delaunay triangulation method. In order to match the fiber units' pixel coordinates of the camera images with the micron coordinates of LAMOST's focal plane, we need to extract feature of each fiber units and match similar feature in micron coordinates and pixel coordinates. This paper use delaunay triangulation method to extract feature of each fiber unit, and match the fiber coordinate automatically, Relying on the methods mentioned in this papar, we can automatically and accurately achieve fiber unit matching and use it to detect fiber positioning units.
