Similar to this error previously in opencv, I get the following error when importing cv-bridge: A module that was compiled using NumPy 1.x cannot be run in NumPy 2.0.0 as it may crash. To support both 1.x and 2.x versions of NumPy, modul...
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.listWebsite may be down. 解决方法,执行下面指令 1、cd /etc 2、sudo gedit hosts 1. 2. 这是要修改个根目录下etc文件夹中hosts文件,在里面添加 151.101.84.133 raw.githubusercontent.com 1. 修改完后保存退出,...
然后去Github的网站github.com/ros-percepti,下载vision_opencv包,里面有cv_bridge,我下载的是1.14的版本,3.几的和2.多的应该是为ROS2准备的,编译通不过下载好之后解压,进入文件,打开cv_bridge,修改cmakelist文件,主要是将里面的opencv版本改一下打开终端mkdir build cd build cmake .. sudo make ...
思路来自github.com/open-mmlab/m。例程中是从本地读取bin格式的文件,而ros中需要在回调函数中调用。那么就先把pointcloud2转为numpy类型,numpy类型就可以输入到mmdet3d框架中了。核心代码如下: from mmdet3d.apis import init_model, inference_detector from mmdet3d.core.points import get_points_type #填写自己...
Failed to connect to raw.githubusercontent.com port 443: Connection…… 我们需要在域名解析查询网站上查询对应的 ip ,然后添加到 hosts 中,域名解析网站推荐:http://dbcha.com/?t=1675223502 sudo gedit /etc/hosts 添加后如下: 这样我们再次执行就不会报错了 ...
第一个终端输入:roscore 第二个终端输入:rosrun turtlesim turtlesim_node 第三个终端输入:rosrun turtlesim turtle_teleop_key 二、PX4源代码配置 1、安装git工具:sudo apt install git 2、克隆源代码及子模块(需要科学上网,自行搜索):git clone --recurse-submodules --branch v1.12.3 https://github.com/PX4...

这里我使用cv_bridge + face_racognition在ROS系统下进行人脸识别项目的开发。关于face_recognition的内容大家可以自行百度,在CSDN可以直接下载整个项目。https://github.com/ageitgey/face_recognition 我这里也提供了我自己整理好的代码文件...
