Problems solved by technology
[0004] However, since the positioning information given by the IMU using the positioning system, such as initial position information and initial velocity information, may be inaccurate, as time goes by, the trajectory calculated by the IMU will quickly diverge, and the accuracy cannot meet the requirements for drawing indoor maps. The need for high-precision scenes such as maps under bridges

The invention belongs to the technical field of electric digital data processing and relates to a trajectory calculation method and device, electronic equipment and a storage medium. The trajectory calculation method comprises steps of obtaining to-be-processed data of a positioning system, taking tail point information in the to-be-processed data as a constraint condition, adjusting starting point information in the to-be-processed data according to a dynamic adjustment rule to obtain optimal starting point information, and obtaining a to-be-calculated trajectory according to the optimal starting point information and the tail point information. According to the method, the to-be-calculated track can be obtained by calculating the to-be-processed data content, so track calculation precision is improved.
Description
Technical field[0001]This application relates to the field of Internet technology, in particular to trajectory calculation methods, devices, electronic equipment, and storage media.Background technique[0002]Positioning systems such as GPS have the characteristics of good performance, high precision, and wide application. In some scenarios, such as under bridges, culverts, tunnels, dense buildings and other locations with poor positioning signals, the trajectory between the initial position and the end position may be missing.[0003]In related technologies, an inertial measurement unit (IMU) can be used to realize the IMU trajectory calculation. Among them, in the IMU trajectory calculation, a certain point can be used as the starting point, and the starting point position information and initial speed information of the starting point can be used as the initial parameters to calculate the position of each time point in the trajectory and draw the trajectory based on the change of the...
