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...

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 ...

Kalibr是一个十分强大的工具箱,提供了很多工具。我们可以使用calibration validator进行标定的验证,原理是对重投影误差进行量化分析。大家可以自行验证。工具使用上一步骤的camera标定结果以及标定板的yaml文件,具体命令如下: kalibr_camera_validator --cam camchain.yaml --target target.yaml ...
