Abstract
An installation angle calibration method implemented in a vehicle-mounted device includes defining a first coordinate system corresponding to an IMU of a vehicle according to first IMU data obtained from the IMU, and determining a rotation angle of a first coordinate system relative to a second coordinate system where the vehicle is located; updating the first coordinate system based on the first rotation angle, and obtaining a third coordinate system corresponding to the IMU; obtaining the second IMU data of the vehicle, and extracting target peak data from the second IMU data; determining a second rotation angle of the third coordinate system relative to the second coordinate system based on the target peak data; and determining the installation angle of the IMU relative to the vehicle based on the first rotation angle and the second rotation angle.
