但是当我们仅使用Imu进行航位推算来与vio进行对比的时候,需要自己计算零偏。 由于手机的imu的精度较低,所以对其进行精细化的标定对于导航性能的提升也较为有限,并且随着数据采集的过程中,手机发热导致imu的物理结构改变,使得零偏、比例因子、不正交等误差也会发生改变。因此,简单的方法为直接静置一小段时间,将平均值当...
Camera IMU calibration using an Extended Kalman Filter is a method for estimating the extrinsic parameters between a camera and an inertial measurement unit (IMU). This process involves fusing data from both sensors to accurately determine the spatial relationship between them. The Extended Kalman ...

A video tutorial for the IMU-camera calibration can be found here: (Credits: @indigomega) How to use it The intrinsic parameters of the IMU (e.g. scales, axis misalignment, nonlinearities,...) need to be calibrated beforehand and its correction applied to the raw measurements. If not, on...
