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...
options = cameraIMUCalibrationOptions creates options for calibrating a transformation between a camera to an IMU with default properties for the estimateCameraIMUTransform function. options = cameraIMUCalibrationOptions(Name=Value) sets properties using one or more name-value arguments. ...
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 ...

标定板可以通过这里进行下载并打印出来:https://github.com/ethz-asl/kalibr/wiki/calibration-targets 打印之后将棋盘格贴在墙上(官方的相机内参标定方法是移动棋盘格相机不动,但是由于纸张不好移动,实际上我标定的时候是动手机纸不动)所以,我在标定内参、以及相机_imu联合标定的时候,实际上用的都是同一组数据(不知...
Camera/IMU boresight calibration is a critical element in the mapping process when using GPS/IMU in the direct georeferencing mode of mapping or even when using the aerotriangulation mapping. Several researchers proved the need for an optimal boresight calibration process, procedure, and software tools...
此功能读取IMU的当前测量值。 基于此测量值(和R_ {IMU} ^ {USV}),它将IMU坐标系中定义的无穷大点旋转到世界坐标系。 通过将所选点从世界坐标投影到摄影机平面,我们可以获取水平线的大致位置。 运行演示 要运行示例校准,只需调用demo_calibration.m脚本。 该脚本需要两个输入参数:(1)MODD2数据集根目录的路径...

In particular, the VIO includes only an Inertial Measurement Unit (IMU) and a camera. In this paper, we present a novel calibration approach for accurate deployment of monocular VIO. For this purpose, the hybrid optimization algorithm is used for calibrating the camera intrinsic and camera–IMU ...
在vio系统中,camera-imu间内外参精确与否对整个定位精度起着重要的作用。所以良好的标定结果是定位系统的前提工作。 目前标定算法主要分为离线和在线标定,离线标定以kalibr为代表,能够标定camera内参、camera-imu之间位移旋转、时间延时以及imu自身的刻度系数、非正交性等。
