基于窄带反射滤光阵列的光谱偏振形貌多模态成像方法
Spectral-Polarimetric Multimodal Imaging Method Based on Narrowband Reflective Filter Arrays
摘要
Abstract
To meet the demands for precise target recognition and multidimensional information acquisition in complex scenarios,this paper precents an integrated multispectral-polarimetric-topographic imaging system sharing a common optical path.The system employs a narrowband reflective filter array and a micro-polarization modulation array to capture multispectral,multi-polarization-state images.It is compactly integrated with the topographic channel of a near-infrared lidar,enabling simultaneous acquisition of multispectral-polarimetric information along with intensity and depth data.Building upon this foundation,an automatic tri-modal registration and fusion algorithm is propased for intensity-spectral-depth data.Through scale estimation,coarse registration via similarity transformation,fine registration based on mutual information,and edge-phase correlation,the algorithm achieves pixel-level alignment of the three modalities within a common field of view and enables multi-pseudo-color fused display.Indoor experimental results demonstrate stable imaging quality and registration accuracy sufficient for multimodal information fusion.Multispectral polarization and topographic data exhibit strong complementarity in material differentiation,edge enhancement,and spatial-structure representation.This study provides a theoretical basis and technical support for material identification,structural perception,and multidimensional collaborative detection of complex targets in the field of aerospace remote sensing and related applications.关键词
