安装ceres出现以下报错，将2版本的ceres换成1版本的ceres

CMake did not find one.

  Could not find a package configuration file provided by "absl" with any of
  the following names:

    abslConfig.cmake
    absl-config.cmake

  Add the installation prefix of "absl" to CMAKE_PREFIX_PATH or set
  "absl_DIR" to a directory containing one of the above files.  If "absl"
  provides a separate development package or SDK, be sure it has been
  installed.

ros2 <-> ros1
ros1_bridge

ROS 1 和 ROS 2 的环境变量不能同时写入 .bashrc 文件中，因为它们的环境变量会相互冲突=>>手动切换环境

sudo apt update
sudo apt install ros-galactic-ros1-bridge

标定

• IMU标定

IMU标定参考港科大imu_utils框架：https://blog.csdn.net/qq_35616298/article/details/116190164

要先下载code_util编译，再下载imu_utils

code_util可能出现opencv版本号不符合的报错，更换opencv写法

注意：当工作空间里面有非ros包时，要用catkin_make_isolated，而非catkin_make

编译imu_utils出现以下报错，在mu_an.cpp加入#include <fstream>的头文件

/home/liuchengyi/imuCali_ws/src/imu_utils/src/imu_an.cpp:90:19: error: aggregate ‘std::ofstream out_t’ has incomplete type and cannot be defined
   90 |     std::ofstream out_t;

• screen是后台运行一个终端

查看所有后台的终端

screen -ls 

关闭某个名为172199.pts-1.nvidia-desktop的终端

screen -X -S 172199.pts-1.nvidia-desktop quit  

• 远程拷贝录制bag

scp 20250103_102425.bag liuchengyi@192.168.111.171:/home/liuchengyi/Desktop

• vscode远程连接断掉

fn + f1重启

• roscore端口占用

查看端口占用情况

sudo lsof -i :11311

终止占用端口的进程

sudo kill <PID>

• 双目标定

帮我把/wrapper/psdk_ros2/acceleration_body_raw和/wrapper/psdk_ros2/angular_rate_body_raw数据合并成 sensor_msgs/Imu类型的名为/dji/imu话题的数据，并且把/wrapper/psdk_ros2/perception_stereo_left_stream和/wrapper/psdk_ros2/perception_stereo_right_stream分别改名为/dji/left/camera和/dji/right/camera名称的同类型Image话题发布，并且把新生成的三个话题存储到rosbag中，完成python代码
