参考拓扑驱动的宽场显微成像非参数化畸变校正OA

A reference topology driven non-parametric distortion correction method was proposed.Firstly,a multi-chain neighborhood tracing algorithm was designed,in which the local connectivity prior of feature point arrays was utilized to replace global coordinate constraints,and the reference topology of distorted lattices was robustly constructed without pose information.Subsequently,based on the reference topology,correction benchmarks were hierarchically established via a center-anchored strategy,and a radial basis function(RBF)interpolation model was introduced to reconstruct and superimpose distortion components,whereby the composite distortion field was accurately reconstructed.Simulation results show that robust distortion correction is achieved by the proposed method under challenging conditions such as large-angle rotation,composite distortion,and missing feature points.Experimental results of distortion correction for large-field-of-view stitching of display panels demonstrate that the geometric consistency of component circuits in the stitching area is significantly improved by the proposed method.
