我首先使用这个从源安装了openCV。当我测试它时,它工作得很好。
在我安装了,打开python3并运行import cv2之后,得到了以下错误:
Python 3.5.2 (default, Nov 17 2016, 17:05:23)

我用cuda支持编译了OpenCV,它在一个不使用ROS的程序中运行得很好。
我在ROS Kinetic中创建了一个节点,它使用OpenCV CUDA实现算法并使用catkin_make编译它,并指向/usr/local中的OpenCV安装。catkin_make的输出如下所示:
-- The C compiler identification is GNU 5.4.0
-- The CXX compiler identification is GNU 5.4.0
-- Check for working C compiler: /usr/bin/gcc

我想安装sudo apt-get install ros-kinetic-cv-bridge,但有时忽略安装ros-kinetic-opencv3
当使用此命令sudo apt-get install ros-kinetic-cv-bridge时,两者都类似于以下输出:

我开发了一些ROS软件包,我想把这些包放在一个码头容器中,因为一直安装所有的ROS软件包都很繁琐。因此,我创建了一个dockerfile,它使用一个基本的ROS映像,安装了所有必要的依赖项,复制了我的工作区,在docker容器中构建了工作区,并随后获取了所有内容。您可以在这里找到码头文件:

我正在尝试在ubuntu16.04上安装动态ros,遵循http://wiki.ros.org/kinetic/Installation/Ubuntu指南。 当我在terminal:sudo apt-get update中编写代码时,问题开始了,结果的简历是这样的: W: The repository «http://packages.ros.org/ros/ubuntu $ (lsb_release Release» does not have a Publication file.

当试图将mavros添加到时,我rosdep抛出一个错误。
按照指令的指示,我将以以下方式结束:
rosdep install --from-paths src --ignore-src -y
但是得到错误:

几个小时以来,我患上了一种很好的未治疗的依赖型癌症,我在ROSAnswers中问过这个问题,在那里我被告知这是一个Ubuntu问题,因此我在这里提出问题。
