  • Patent number: 11967006
    Abstract: Systems and methods for generating a road map are provided. The methods include obtaining a navigation route for a navigation terminal and a current location of the navigation terminal. The methods further include obtaining road network data associated with the current location of the navigation terminal based on the navigation route and the current location of the navigation terminal. The road network data includes a plurality of links and a plurality of nodes. Each node is connected to one or more links including at least one type of links. The methods further include determining a level for each node. The methods further include determining one or more target links for the at least one type of links connected to the node based on the level of the node. The methods further include generating a road map based on the target links.

  • Patent number: 11719623
    Abstract: The present invention belongs to the technical field of new energy detection, in particular to a material uniformity detection device and method. The purpose of the present invention is to provide a material uniformity detection device which can meet the requirement of detection of diversified materials such as biomass slurry aiming at the problem of difficulty in quantifying uniformity state of the biomass slurry. The sample pool is driven by the rotating lifting device for lifting and spiral motion, data collection is performed on the sample pool in the form of a certain path, and an image is established for the relationship between a large number of light intensity values of transmission light and heights measured for multiple times to respectively display the uniformity of horizontal layering and uniformity in the vertical direction, to judge the overall uniformity of the material samples.
