How to install Kalibr I was confused about installing Kalibr, but there is no even one hint in README.md. I just put them in the catkin_ws, in which so many ROS packages are also there. Unsuccessfully, it can't be compiled one by one packages by the
单目相机IMU标定 该论文将相机IMU标定分为两个大方面: 一. 使用基函数来估计时间偏差 二. 相机和IMU的空间位置转换 校准变量:重力.外参旋转和平移.时钟偏移.IMU位姿.加速度计偏置.陀螺仪偏置. 校准过程: (1) 校准前有如下假设: a. 相机内参已知 b. IMU噪声和偏置模型已知 c. 对重力有个初始猜测值 d. 对外参有个初始估计值 e. 标定板的参数是知道的,所以我们可以算出每个标志点的空间位置 f. 知道像素点和空间点的对应关系 (2) IMU位姿使用6阶B样条来表示,首

1. 第一步初始化imu外参(可以从参数文档中读取,也可以计算出),VINS中处理如下: # Extrinsic parameter between IMU and Camera. estimate_extrinsic: # Have an accurate extrinsic parameters. We will trust the following imu^R_cam, imu^T_cam, don't change it. # Have an initial guess about e
