github source: https://github.com/googlecartographer/cartographer_turtlebot 1. Building & Installation Installation has been tested on Ubuntu 14.04 (Trusty) with ROS Indigo, but may also work on Ubuntu 16.04 (Xenial) with ROS Kinetic. We recommend us…

1.验证自己的bag cartographer ROS提供了一个工具cartographer_rosbag_validate来自动分析包中的数据.在尝试调试cartographer之前运行这个工具. 操作方式: cartographer_rosbag_validate -bag_filename your_bag.bag 2.创建一个.lua配置文件 cartographer非常灵活且可以配置用于任何机器人上.机器人配置读取来自于一个options的数据结构,该数据结构必须定义在一个Lua脚本里…

1.系统要求 cartographer ROS与Cartographer要求一样,即 64-bit, modern CPU (e.g. 3rd generation i7) 16 GB RAM Ubuntu 14.04 (Trusty) and 16.04 (Xenial) gcc version 4.8.4 and 5.4.0 支持的ROS版本: Indigo Kinetic Lunar Melodic 编译并安装 为了编译Cartographer ROS,推荐使用wstool 和 rosde…

上一节介绍了在cartographer进行建图和定位(在线和离线). 本节将分析cartographer运行时的误差与延迟,主要是在线定位时的,并尝试优化解决. 目录 1,误差分析 a,硬件精度 b,初值敏感 c,计算量大 2,延时优化 本地 全局 减少重复子图 3,简单小结 1,误差分析 建图时的漂移,重影等现象基本可以通过: 确保雷达足够的频率和角度: 建图时移动速度均匀且不要过快: 调整建图参数:足够多的迭代优化: 融合里程计+陀螺仪等方式解决. 这里的误差主要指在实时定位的定位错差. a…

注意在运行bag包,之前需要去执行source install_isolated/setup.bash 1.Deutsches Museum 下载并启动2D的backpack demo: wget -P ~/Downloads https://storage.googleapis.com/cartographer-public-data/bags/backpack_2d/cartographer_paper_deutsches_museum.bag roslaunch cartographer_…

Cartographer is a backpack equipped with Simultaneous Localization and Mapping (SLAM) technology. 1. Platform Dell PC installed Ubuntu 14.4 and ROS Indigo. 2. Building & Installation We recommend using wstool and rosdep. For faster builds, we also re…

What is Cartographer? Google announce the open source release of Cartographer, a real-time simultaneous localization and mapping (SLAM) library in 2D and 3D with ROS support, in October 2016. As Robotics Trends said, "Google wants to democratize the…

中文资料稍后补充 Introducing Cartographer By Tully Foote on October 5, 2016 10:11 AM From Damon Kohler, Wolfgang Hess, and Holger Rapp, Google Engineering We are happy to announce the open source release of Cartographer, a real-time SLAM library in 2D and 3D…

0 引言 刚刚入门学了近一个月的SLAM,但对理论推导一知半解,因此在matlab上捣鼓了个简单的2D LiDAR SLAM的demo来体会体会SLAM的完整流程. (1)数据来源:德意志博物馆Deutsches Museum)的2D激光SLAM数据,链接如下: Public Data - Cartographer ROS documentationgoogle-cartographer-ros.readthedocs.io (2)SLAM过程展示(戳下面的小视频) 2D LiDAR SLAM…

建地图前说明:请确保你的小车已经校正好 IMU.角速度.线速度,虚拟机配置好 ROS 网络的前提进行,否则会造成构建地图无边界.虚拟机端无法正常收到小车主控端发布的话题数据等异常情况!! 1.把小车平放在你想要构建地图的区域内地板上,用资料里的虚拟机,打开一个终端 ssh 过去主控端启动 roslaunch znjrobot bringup.launch. 2.在虚拟机端,再打开一个终端,ssh 过去小车主控端启动, roslaunch znjrobot rplidar.launch 3.在虚拟…
