时-谱动态约束的光谱波段自适应成像探测
Spectral band adaptive imaging detection with temporal-spectral dynamic constraints
摘要
Abstract
Spectral detection technology holds significant application value in the field of UAV perception,where its multi-dimensional information acquisition capability substantially enhances target recognition accuracy and environmen-tal adaptability.However,conventional hyperspectral imaging systems,relying on fixed-band acquisition modes,suf-fer from complex hardware architectures,low efficiency,and high data redundancy,thereby failing to meet the de-mand for rapid and low-cost target detection in UAV platforms.To address these challenges,this paper proposes an adaptive spectral band imaging detection algorithm,enabling dynamic adjustment of spectral parameters and the de-sign of structurally simplified optical imaging systems.First,a spectral imaging quality evaluation framework based on information entropy and target separability is established to quantitatively assess the recognition contributions of narrow-band spectral data.Second,a spectral adaptive model incorporating constraints of minimum switching time intervals and maximum spectral switching ranges is developed,achieving an optimal balance between target feature discrim-inability and data dimensionality reduction.Finally,an integrated imaging detection system structure is designed using array-based optical modules.Experimental results validate the effectiveness of the proposed method,offering a novel and efficient solution for UAV-based spectral perception.关键词
