Abstract: The technical field of enzyme immobilization, and particularly, an organic-inorganic hybrid nanoflower and a preparation method thereof. The organic-inorganic hybrid nanoflower is a flower-like immobilized enzyme formed by self-assembly of a layered rare earth compound as an inorganic carrier and a biological enzyme as an organic component. The layered rare earth compound is Ln2(OH)5NO3·nH2O, where Ln is one or more of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, or Y, and n=1.1-2.5. The biological enzyme is one or more of α-amylase, horseradish peroxidase, or laccase. A layered rare earth compound is used as the inorganic carrier for the organic biological enzyme to form the flower-like immobilized enzyme. The immobilized enzyme has better stability and higher catalytic performance when compared with a free enzyme.

Abstract: The present disclosure relates to a PointEFF method for urban object classification with LiDAR point cloud data, and belongs to the field of LiDAR point cloud classification. The method comprises: point cloud data segmentation; End-to-end feature extraction layer construction; External feature fusion layer construction; and precision evaluation. The PointEFF method for urban object classification with LiDAR point cloud data fuses point cloud hand-crafted descriptors with End-to-end features obtained from a network at an up-sampling stage of a model by constructing an External Feature Fusion module, which improves a problem of local point cloud information loss caused by interpolation operation in the up-sampling process of domain feature pooling methods represented by PointNet and PointNet++, greatly improves classification precision of the model in complex ground features, especially in rough surface ground features, and is capable of being better applied to the classification of urban ground features with complex ground feature types.
