sensor-fusion-for-localization-courseware's Issues

[laser_odom状态报错，evo无法评价]-[WEEK2]

#第二章代码# 运行结束时使用rosservice call /save_map 报错,如何解决？

Screenshots
If applicable, add screenshots to help explain your problem.

具体描述

第二章直接法推导最优位姿时使用的右扰动模型，但是第三章又使用了左扰动模型，请问哪一种是适合在帧间匹配时使用？

第一章中网页的虚拟机屏幕分辨率低

第一章中网页的虚拟机屏幕分辨率低
文档说配置参数，查一圈还是不知道怎么配置，
想让这个分辨率改一下

第四章代码

老师，第四章代码未作修改编译后，roslaunch lidar_localization mapping.launch 运行到一半后端节点报错，且transformed_odom不再更新，gnss轨迹能更新，如图所示，未做修改出现该问题原因是和电脑有关嘛？用的本地环境，装的库和readme中版本一致。谢谢老师解答。

代码编译

老师好，我把#include "lidar_localization/models/registration/sicp/ICP.h" 从 scip_registration.cpp移动到 scip_registration.hpp下，编译时产生多次定义的错误，需要注释掉ICP.h中的 IWICP 的命名空间才能通过，是只有我电脑有这个问题吗（虽然并不影响结果），谢谢老师。

第四章代码g2o优化地图时会报Segmentation fault

第四章代码框架在使用时，每次一到g2o优化地图的地方，就会报segmentation fault的错误。比如调用service 优化地图，或者不调用service，但是bag跑到300多秒的时候，由于会自动调用g2o optimize,都会出现segmentation fault。

icp_svd

老师，请问自己实现的icp_svd轨迹前面还正常，后面尺度就越飘越大，有什么解决办法么？

本地ubuntu部署环境,按照cpu.Dockerfile中指导的版本进行安装,编译成功,但是除了master能运行成功,其他分支均报内存异常.

[雷达运动补偿图示的理解]-[WEEK02]

Describe the bug
关于雷达运动补偿的公式图示理解

我画了个图，黑色线代表T0 Ti Pi在世界系下的含义，红色线代表对上图红色框里公式的理解

请问T0 Ti Pi含义的理解是否正确？公式推导的理解是否正确？

evo运行报错

老师，请问这个问题怎么解决呀？在主机和docker上都不行

[docker启动报错]-[WEEK1]-[更换了docker根目录的名称，docker启动报错]

Describe the bug
给repo名称前加了一个01序号，然后原来的docker就无法启动了，报了如下的错误，请问如何解决？

Screenshots

安装完docker后连接镜像源时报错

Error response from daemon: Get "https://registry.cn-shanghai.aliyuncs.com/v2/": unauthorized: authentication required

[docker内git branch显示错误]-[WEEK2]

第一章中网页上的虚拟机，显示不对

文档说配置参数，查一圈还是不知道怎么配置，想让这个分辨率改一下

this is a bug: it should be "Eigen::VectorXd"

Sensor-Fusion-for-Localization-Courseware/workspace/assignments/02-lidar-odometry-basic/src/lidar_localization/include/lidar_localization/models/registration/sicp/ICP.h

Line 367 in 24bd9e9

    
           Eigen::VectorXf P = (Qn.array()*(X-Qp).array()).colwise().sum().transpose()-Z.array();

docker-compose down && docker-compose up出现报错

通过clone新的github上面的工程，再新的下载根目录中查看运行的容器显示没有
itcast@ubuntu:/Sensor-Fusion-for-Localization-Courseware$ docker ps

执行docker-compose down && docker-compose up报错如下
