Estimation of Coniferous Forest Height using Stereo Images of GF-7 Satellite and Airborne Lidar Data
IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2022Forest height is a key parameter of forest spatial structure, which is useful for forest management and ecosystem modelling. High resolution stereo images of satellite can be used to reconstruct the surface of ground objects.

Impact of atmospheric correction on 3D reconstruction using GF-7 satellite imagery
Third International Conference on Remote Sensing, Mapping, and Geographic Information Systems (RSMG 2025)The GF-7 satellite possesses stereoscopic imaging capability, which can generate surface point clouds through dense matching in 3D reconstruction. Conventional photogrammetric processing directly uses uncalibrated digital number (DN) images, and the ...

AbstractQuantifying surface deformation due to earthquake-related surface rupturing is a critical research focus. Localized offsets on the primary fault can be obtained via field measurements of dislocated landforms. However, effectively quantifying distributed deformation, which can extend for tens to hundreds of meters around the fault zone, has only

Robust Coregistration of GF‐7 Panchromatic and Multispectral Satellite Imagery
Photogrammetric RecordHigh‐precision coregistration of panchromatic (PAN) and multispectral (MS) satellite images is critical for remote sensing applications. The traditional methods use image matching to obtain homologous image points and then establish a mapping ...
