Abstract: The present disclosure provides a method and a system for modelling a poor texture tunnel based on a vision-lidar coupling. The method includes: obtaining point cloud information collected by a depth camera, laser information collected by a lidar, and motion information of an unmanned aerial vehicle (UAV); generating a raster map based on the laser information, and obtaining pose information of the UAV based on the motion information; obtaining a map model through fusing the point cloud information, the raster map, and the pose information by a Bayesian fusion method; and correcting a latest map model by feature matching based on a previous map model.

Abstract: The present disclosure discloses a moving-track sharing method and apparatus, and a storage medium. The method includes: receiving, by an instant messaging client, a track-sharing instruction, wherein the track-sharing instruction is used to instruct the instant messaging client to share a real-time moving-track of a first terminal in a moving event, and the instant messaging client is located on the first terminal; generating, by the instant messaging client, a first track-sharing event in response to the track-sharing instruction; and sending, by the instant messaging client, the first track-sharing event to a server, wherein the first track-sharing event is used to instruct the server to share a real-time moving-track of the first terminal in a manner specified by the track-sharing instruction.

Abstract: A method, a device, and a system for processing information of a vehicle are disclosed. In the embodiments, information about a connected vehicle is acquired, and a display image of a virtual vehicle is generated; driving information of the connected vehicle is acquired; whether the vehicle is currently in a driving state is determined according to the driving information; and when the connected vehicle is in the driving state, an orientation of a head of the virtual vehicle is adjusted to keep consistency with an orientation of a head of the connected vehicle; and when the connected vehicle is in a non-driving state, an orientation of a head of the virtual vehicle is adjusted towards a location of the connected vehicle.
