Research Progress in Data Fusion of LiDAR and Hyperspectral Imaging Technology
In recent years,in order to improve the classification accuracy of ground objects,break through the technical system of single sensor,and make up for the limitations of single data source application,multi-source remote sensing data fusion has become a research hotspot concerned by many scholars in the field of remote sensing.The fusion technology of optical image and LiDAR point cloud data of hyperspectral remote sensing technology provides a feasible scheme to improve the accuracy of ground object recognition and classification at the technical level,breaks the technical upper limit of single sensor,and provides a new solution for the integrat-ed acquisition of target three-dimensional space-spectral information.At the same time,it lays a foundation for the research of hyperspectral LiDAR imaging technology.This paper reviews the development history of Li-DAR and hyperspectral imaging data fusion,discusses the main fusion methods and research progress at the fea-ture level and decision level,introduces the commonly used feature level fusion and decision level fusion meth-ods in detail,summarizes the latest research algorithms and discusses their challenges and future development and application prospects.Finally,the future development of LiDAR and hyperspectral imaging data fusion is prospected systematically.
