Abstract

The invention discloses an indoor vehicle navigation method, a vehicle-mounted terminal, a field end server and a system. According to the method disclosed by the invention, the UWB positioning information of the vehicle-mounted terminal on the carrier can be fused with other auxiliary positioning data through the receiving field end, and the more accurate first positioning data is obtained and sent to the vehicle-mounted terminal. The first positioning data containing the UWB positioning information is fused with the inertial navigation data of the carrier at the vehicle-mounted terminal, so that the self positioning precision of the vehicle-mounted terminal is improved, the real-time performance, stability and precision of positioning of the vehicle in an indoor site are greatly guaranteed; therefore, even under the condition of no GNSS signal coverage, indoor vehicle automatic navigation can be realized based on a high-precision positioning result.

Description

technical field [0001] The disclosure belongs to the technical field of intelligent driving, and in particular relates to an indoor vehicle navigation method, a vehicle terminal, a field server and a system. Background technique [0002] In the intelligent driving technology of vehicles, high real-time and accurate positioning information is required for trajectory planning or automatic parking. Vehicle positioning technology generally relies on GNSS (Global Navigation Satellite System) positioning, but in indoor venues, there is often no GNSS signal coverage or GNSS positioning stability cannot be guaranteed, resulting in the inability of vehicles to realize automatic navigation and parking in indoor venues. Contents of the invention [0003] Embodiments of the present disclosure provide an indoor vehicle navigation method, a vehicle-mounted terminal, a field server, and a system, which can improve the real-time performance and accuracy of vehicle positioning, help meet t...
