Description

technical field [0001] The present application relates to the technical field of navigation, and in particular to a method, device and electronic equipment for estimating a vehicle trajectory. Background technique [0002] A positioning system such as GPS has the characteristics of good performance, high precision, and wide application. However, in some scenarios, such as under bridges, culverts, tunnels, and places with poor positioning signals, the positioning system of related technologies has a large positioning deviation, and even cannot provide positioning results. The inertial measurement unit (InertialMeasurement Unit, IMU), which includes an accelerometer and a gyroscope, can be used to measure the angular velocity and acceleration of an object in inertial space, and to estimate the trajectory of the object. [0003] However, the related technology uses the trajectory estimation process of the inertial measurement unit to perform parameter coupling on the parameter...
