Abstract: This application relates to a method for training a trajectory estimation model. The method includes: obtaining first IMU data in a first time period; obtaining second IMU data, where the first IMU data and the second IMU data use a same coordinate system, and the second IMU data and the first IMU data have a preset correspondence; in a feature extraction module, extracting a first feature of the first IMU data, and extracting a second feature of the second IMU data; in a label estimation module, determining a first label based on the first feature, and determining a second label based on the second feature; determining a first difference between the first label and the second label; and performing a first update on a parameter of the feature extraction module and a parameter of the label estimation module in a direction of reducing the first difference.
