Abstract:
ZY-1 02E satellite is a Chinese hyperspectral satellite launched in recent years. There are few reports on its application at present, so there is no suitable research method. In this study, rice planting area was extracted from two experimental areas of Fujian Province using Ziyuan No. 1 02E hyperspectral data. A multi-scale spectral feature extraction network Based on spatial neighborhood (MSFEN-BSN) was proposed to solve the high spectral resolution, low spatial resolution and complex and fragmented distribution of crops in the experimental area. The network consists of two modules: Multi-scale Spectral Feature Extraction (MSFE) and Spatial Neighborhood Feature Fusion (SNFF), which can extract spectral features at multiple scales to obtain deep spectral semantics, and fuse spectral-spatial information of neighboring pixels to obtain more effective classification features. The mapping accuracy of rice classification in two experimental areas reached 83.61% and 84.36% respectively, which can meet the needs of practical application. Meanwhile, to prove the robustness of the proposed method, precision verification is carried out on two public vegetation datasets Indian pines (IP) and Salinas Valley (SA). Compared with some traditional vegetation extraction methods and classical deep learning methods, the proposed method has higher precision. © 2024 Copyright held by the owner/author(s).
