  • Publication number: 20240099179
    Abstract: The present disclosure provides a machine learning-based hyperspectral detection and visualization method of a nitrogen content in a soil profile. The method includes the following steps: collecting a plurality of soil profile samples; obtaining hyperspectral image data of a soil profile; selecting a plurality of rectangular ranges on a hyperspectral image as region of interest (ROIs), calculating an average spectral curve of all pixels in the ROIs, and analyzing and measuring standard contents of nitrogen in the soil samples corresponding to the ROIs; constructing hyperspectral prediction models of five types of soil nitrogen in the soil profile with reference to different learning algorithms respectively with an average spectrum of ROIs after preprocessing as a predictive variable and a standard soil nitrogen content as a response variable; selecting an optimal prediction model based on evaluation indexes to predict and visualize contents of different forms of nitrogen in the entire soil profile.

  • Patent number: 10397045
    Abstract: A method for migrating a service of a data center is disclosed. When an active data center is faulty, a tunnel processing device disables a locally-saved tunnel entry of a server in the active data center. After receiving a service access request packet from a customer edge router, the tunnel processing device acquires an IP address of a tunnel processing module deployed on a server in a standby data center according to an IP address of a destination virtual machine, encapsulates the service access request packet and routes the encapsulated packet to the tunnel processing module, so as to migrate a data center service from the active data center to the standby data center.
