Visual positioning method and apparatus, electronic device and system

A visual positioning method and apparatus, an electronic device, and a system are provided. The method includes: detecting a lane line of a vehicle traveling road surface based on a video stream of the vehicle traveling road surface that is collected by a camera mounted on a vehicle; determining first reference point information at a current angle of view of the camera according to a detection result of the lane line; determining a third homography matrix according to the first reference point information and second reference point information, where the second reference point information is reference point information at a previous angle of view of the camera, the position of a second reference point corresponds to that of a first reference point, and the third homography matrix is used for representing a mapping relationship between a coordinate of the camera at the current angle of view and a coordinate of the camera at the previous angle of view; determining a first homography matrix according to the third homography matrix and a predetermined homography matrix; and performing positioning according to the first homography matrix.

Trajectory prediction method and apparatus, device, storage medium and program

Provided are a trajectory prediction method, an electronic device, and a storage medium. The method including that: a motion intention of an object is determined according to time-series location information and time-series posture information of the object, where the time-series location information is position information of the object at different time points within a preset time period, and the time-series posture information is posture information of the object at different time points within the preset time period, where the posture information at different time points includes orientation information of multiple parts of the object at the different time points; and a future trajectory of the object is determined according to the time-series location information, the time-series posture information and the motion intention.
