Study on calculating projection deformation of measured length using an amended particle swarm optimization
In order to best control the projection deformations, this paper studied an amended Particle Swarm Optimization (PSO) algorithm, which could synchronous search multi-dimensional solution spaces those with large differences in magnitudes.To estimate the advantages of this new method, a contrast calculation between PSO algorithm and traditional optimization scheme was made subsequently.When using this modified PSO algorithm presented in this paper, the maximum deformation is 2.04 cm/km.This result indicate that both the location of the central meridian and the mean geodetic height within a same region affect the projection deformations.It could decrease affections of a certain central meridian longitude on projection deformations and expand the permitted differences of geodetic heights of a surveying area.
