环境依赖：PCL1.9 tensorflow1.8.0 ros （pcl1.9 及 ros自行配置 ros配置时推荐用国内源） 2020年最近rosdep不易成功具体方法需要 sudo gedit /etc/resolv.conf 删掉其中所有内容替换为 nameserver 8.8.8.8 #google域名服务 nameserver 8.8.4.4 #google域名服务器 下面开始正题 一、下载源码及虚拟环境 $ sudo apt-get install python-wstool doxygen python3-pip python3-dev python-virtualenv dh-autoreconf $ cd ~/segmap_ws $ catkin init $ catkin config --merge-devel $ catkin config --cmake-args -DCMAKE_BUILD_TYPE=Release $ cd src $ git clone https://github.com/ethz-asl/segmap.git $ wstool init $ wstool merge segmap/dependencies.rosinstall $ wstool update $ virtualenv ~/segmappyenv $ source

SLAM拾萃(1)：octomap

前言 　　大家好，时隔多年之后，我又开始了博客旅程。经历了很多事情之后呢，我发现自己的想法真的很简单：好好读书做课题，闲下来时写写博客，服务大家。所以我会继续写SLAM相关的博客。如果你觉得它对你有帮助，那是最好不过的啦！写作过程中得到了许多热心读者的帮助与鼓励，有些读者还成了要好的朋友，在此向大家致谢啦！关于SLAM，读者也会有很多问题。由于我个人精力和学力都有限，无法一一回答，向大家说声抱歉！有些共同的问题，我肯定会在博客里介绍的！ 　　前两天刚从珠海开会回来，与中山大学的同学们聚在一起玩耍，很开心！ 　　《一起做》系列已经结束，事实上它是我以前探索过程中的一些总结。虽然仍然有很多令人不满意的地方，不过相信读了那个系列，读者应该对SLAM的流程有一定的了解了。尤其是通过代码，你能知道许多论文里没讲清楚的细节。在这之后，我现在有两个规划。一是对目前流行的SLAM程序做一个介绍，沿着《视觉SLAM实战》往下写；二是介绍一些好用的开源工具/库，写成一个《SLAM拾萃》。我觉得这两部分内容，对读者了解SLAM会有较大的帮助。当然，如果你对我的博客有任何建议，可以在下方评论或给我发邮件。 　　本篇是《SLAM拾萃》第一篇，介绍一个建图工具：octomap。和往常一样，我会介绍它的原理、安装与使用方式，并提供例程供读者学习。必要时也会请小萝卜过来吐槽。（小萝卜真是太好用了

问题 I have rather a basic knowledge in c++ and there is an issue described in the following which is likely rather simple and a based on a syntax mistake but I haven't figured out a way around it. Basically the error I get says: remote_hw_interface_node.cpp:23:68: required from here /usr/include/boost/function/function_template.hpp:231:11: error: no match for call to ‘(boost::_mfi::mf1<void, ROBOTHardwareInterface, const boost::shared_ptr<sensor_msgs::JointState_<std::allocator<void> > > >&>)

问题 I'm able to display data from two topics but I can't do use and compute data in real time from these two topics in ROS (written in Python code).

ROS message_filters::TimeSequencer

问题 I'm trying to delay processing of some input received via ros topics and as I was reading over the message_filters package information, TimeSequencer seemed to do just this. They even include some example code which I copied, but cannot get it to compile whatsoever. I have pasted the small test program that produces errors here: #include "ros/ros.h" #include <message_filters/subscriber.h> #include <message_filters/time_sequencer.h> #include <std_msgs/String.h> void callback(const std_msgs:

How to source additional environment in pycharm?

由 南笙酒味 提交于 2020-06-17 02:01:18
问题 I have a ROS application which has a work space with a setup.bash file and another python script with its own virtual environment. So far this is what I do in my terminal: 1_ pipenv shell (to activate my python virtual environment). 2_ source ../ros_workspace/devel/setup.bash 3_ python some_python_script.py This code works as I expect. However, I want to do the same and run this script in pycharm, where my virtual environment is already activated. But how do I source the setup bash
