这里用源码安装
#
git clone https://github.com/MichaelGrupp/evo.git
cd evo
# 安装在系统的python2 使用清华源 并开启usr
#可以尝试安装在python3pip install --editable . --upgrade --no-binary evo -i https://pypi.tuna.tsinghua.edu.cn/simple --user#出现问题
#更新numpy 和matplotlib的版本
pip install numpy --upgrade --user
pip install matplotlib --upgrade --user
#如果更新不了 发现加上清华源即可
pip install numpy --upgrade --user -i https://pypi.tuna.tsinghua.edu.cn/simple
pip install matplotlib --upgrade --user -i https://pypi.tuna.tsinghua.edu.cn/simple再次在python2.7装，找不到evo_traj，pip uninstall evo了，以下信息 :
装在了 ./local ？？？ 什么情况
solved 2020.12.21
首先git所有的内容，采用编译安装的方法
git clone https://github.com/MichaelGrupp/evo.git
cd evo现在evo又更新了，支持python3.6+，还是习惯用python2.7, 切到这个分支tag https://github.com/MichaelGrupp/evo/tree/v1.12.0
git checkout v1.12.0安装就完了，pip对应python2, pip3默认对应pthon3
pip install --editable . --upgrade --no-binary evoWARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

于是 用sudo ，evo可以被tab了

修改mskcf 保存轨迹
参考 https://github.com/symao/msckf_vio/blob/evaluation/src/msckf_vio.cpp
https://github.com/symao/vio_evaluation
修改msckf源码，用tum格式（为了便于用evo 进行euroc的评价）
在msckf_vio.cpp开头增加如下
#在头文件增加
#include <thread> #在这一句map<int, double> MsckfVio::chi_squared_test_table; 大概50行之后增加：
#if 1
static const int p_max_cnt = 10000;
static const int p_cols = 8;
static double *p_log_data = new double[p_max_cnt * p_cols];
static int p_cnt = 0;
void mylog()
{FILE* fp = fopen("/home/lincent/s_msckf_ws/vio.txt","w");int k = 0;while(1){if(k < p_cnt){for(int i=0; i<p_cols; i++){if(i > 0) fprintf(fp, " ");fprintf(fp, "%f", p_log_data[p_cols * k + i]);}fprintf(fp, "\n");fflush(fp);k++;}else{usleep(100000);}}fclose(fp);
}
static std::thread th_log(mylog);
#endif完成上述 大约在470行
if (processing_time > 1.0/frame_rate) { ...} 后增加:
#if 1const auto& s = state_server.imu_state;const auto& p = s.position;const auto& q = s.orientation;const auto& v = s.velocity;const auto& ba = s.acc_bias;const auto& bg = s.gyro_bias;double *lp = p_log_data + p_cnt * p_cols;lp[0] = s.time;lp[1] = p(0);lp[2] = p(1);lp[3] = p(2);lp[4] = q.w();lp[5] = q.x();lp[6] = q.y();lp[7] = q.z();//lp[8] = v(0);//lp[9] = v(1);//lp[10] = v(2);//lp[11] = ba(0);//lp[12] = ba(1);//lp[13] = ba(2);//lp[14] = bg(0);//lp[15] = bg(1);//lp[16] = bg(2);//lp[17] = processing_time;p_cnt++;
#endif重新编译msckf，运行得到结果vio.txt
#！！！注意：这里一定要用release进行make，不然运行会出现大问题
catkin_make --pkg msckf_vio --cmake-args -DCMAKE_BUILD_TYPE=Release
source devel/setup.bash
#运行，结束得到 位姿txt
