This study investigates whether spatial alignment in multimodal representation learning degrades modality-specific information—particularly in remote sensing fusion of heterogeneous sources (e.g., optical and SAR). We first establish a theoretical analysis framework revealing how alignment operations inherently erode modality-unique semantic content. To address this, we propose a self-supervised contrastive learning paradigm that jointly optimizes semantic alignment and modality fidelity. Extensive experiments on real-world remote sensing datasets demonstrate that aggressive spatial alignment improves cross-modal consistency but substantially compromises modality-discriminative feature representation. Our method preserves alignment performance while boosting modality-specific representation capability by 12.7% (average improvement). The work provides an interpretable trade-off principle between alignment and specificity for multimodal remote sensing fusion and releases open-source code and a benchmark dataset.
This work addresses the challenging problem of pose estimation and 3D reconstruction for non-cooperative space targets under severe conditions—including monocular imaging, unknown initial pose, limited field-of-view, and non-Lambertian illumination. To this end, we propose an end-to-end framework that jointly optimizes a neural radiance field (NeRF) and camera poses. Our method integrates differentiable rendering with frame-wise pose refinement and introduces a rotation-consistency regularizer to mitigate pose ambiguity and reconstruction degradation caused by sparse observations. Compared to conventional sequential optimization pipelines, our approach achieves higher geometric reconstruction accuracy and more stable pose convergence on synthetic space imagery. It significantly enhances robustness of 3D perception and improves spatial situational awareness under weakly supervised conditions.
