一起学ROS+AI 开篇 ros部署yolov8

博主是新手小白,所以该专栏名为“一起学ROS+AI”,本篇为此专栏第一篇,欢迎一起学习交流。

环境 ubuntu20.04+ros2 foxy

假设环境已经搭建好,以后再补上环境安装篇。

yolov8在ros2上github地址:

GitHub - mgonzs13/yolov8_ros: Ultralytics YOLOv8 for ROS 2

为了方便使用,fork到gitee,也可也使用下面这个链接:

https://gitee.com/chenjianbin0822/yolov8_ros

步骤:

1. source /opt/ros/foxy/setup.sh

2. 按照仓库Installation进行安装:

$ cd ~/ros2_ws/src
$ git clone https://github.com/mgonzs13/yolov8_ros.git
$ pip3 install -r yolov8_ros/requirements.txt
$ cd ~/ros2_ws
$ rosdep install --from-paths src --ignore-src -r -y
$ colcon build

博主之前已经测试过,从以下开始

2.1. rosdep install --from-paths src --ignore-src -r -y

显示:#All required rosdeps installed successfully

2.2 colcon build

显示:

Starting >>> yolov8_ros
Starting >>> yolov8_msgs                 
Finished <<< yolov8_ros [1.98s]                                                 
Starting >>> yolov8_bringup
Finished <<< yolov8_bringup [5.05s]                                                         
Finished <<< yolov8_msgs [35.2s]                       
                      
Summary: 3 packages finished [36.9s]

3. 执行:. install/setup.sh, 注意,有个”."符号

4. 启动人体关键点算法:

ros2 launch yolov8_bringup yolov8.launch.py model:=yolov8m-pose.pt

显示:

[INFO] [launch]: All log files can be found below YOURPATH/.ros/log/2023-12-16-11-19-34-170991-ubuntu2004-rdk-34339
