cv_bridge

Introduction

cv_bridge converts between ROS 2 image messages and OpenCV image representation for perception applications. As follows:

cv_bridge overview

This ros2 branch initially derives from porting on the basis of ros kinetic branch

Installation

Firstly, it assumes that the ROS 2 core has already been installed, please refer to ROS 2 installation to get started.

Install dependencies

OpenCV3+ is a must to install, please refer to the official installation guide from OpenCV Tutorials Since ROS 2 uses Python 3, please make sure that python3-numpy is installed, or install like this:


sudo apt install python3-numpy


The cv_bridge python backend still has a dependency on python boost (equal or higher than 1.58.0), and install them as follows in Ubuntu:


sudo apt install libboost-python-dev


Build and Test

Fetch the latest code and build


cd <YOUR_ROS2_WORKSPACE>/src
git clone https://github.com/ros-perception/vision_opencv.git -b ros2
cd ..
colcon build --symlink-install


Run the tests

Python tests have a dependency on OpenCV Python support. To install it:


sudo apt install python3-opencv


Next to prepare runtime environment and run tests:


source <YOUR_ROS2_WORKSPACE>/install/local_setup.bash
colcon test


Known issues

  • boost endian: remove boost endian APIs with standard C++ 11 or higher instead
  • Not tested with Windows or macOS environments so there may be issues building or running

The cv_bridge python backend still has a dependency on python boost (equal or higher than 1.58.0), and install them as follows in Ubuntu:


sudo apt install libboost-python-dev


Build and Test

Fetch the latest code and build


cd <YOUR_ROS2_WORKSPACE>/src
git clone https://github.com/ros-perception/vision_opencv.git -b ros2
cd ..
colcon build --symlink-install


Run the tests

Python tests have a dependency on OpenCV Python support. To install it:


sudo apt install python3-opencv


Next to prepare runtime environment and run tests:


source <YOUR_ROS2_WORKSPACE>/install/local_setup.bash
colcon test


Known issues

  • boost endian: remove boost endian APIs with standard C++ 11 or higher instead
  • Not tested with Windows or macOS environments so there may be issues building or running

cv_bridge

Introduction

cv_bridge converts between ROS 2 image messages and OpenCV image representation for perception applications. As follows:

cv_bridge overview

This ros2 branch initially derives from porting on the basis of ros kinetic branch

Installation

Firstly, it assumes that the ROS 2 core has already been installed, please refer to ROS 2 installation to get started.

Install dependencies

OpenCV3+ is a must to install, please refer to the official installation guide from OpenCV Tutorials Since ROS 2 uses Python 3, please make sure that python3-numpy is installed, or install like this:


sudo apt install python3-numpy


The cv_bridge python backend still has a dependency on python boost (equal or higher than 1.58.0), and install them as follows in Ubuntu:


sudo apt install libboost-python-dev


Build and Test

Fetch the latest code and build


cd <YOUR_ROS2_WORKSPACE>/src
git clone https://github.com/ros-perception/vision_opencv.git -b ros2
cd ..
colcon build --symlink-install


Run the tests

Python tests have a dependency on OpenCV Python support. To install it:


sudo apt install python3-opencv


Next to prepare runtime environment and run tests:


source <YOUR_ROS2_WORKSPACE>/install/local_setup.bash
colcon test


Known issues

  • boost endian: remove boost endian APIs with standard C++ 11 or higher instead
  • Not tested with Windows or macOS environments so there may be issues building or running

cv_bridge

Introduction

cv_bridge converts between ROS 2 image messages and OpenCV image representation for perception applications. As follows:

cv_bridge overview

This ros2 branch initially derives from porting on the basis of ros kinetic branch

Installation

Firstly, it assumes that the ROS 2 core has already been installed, please refer to ROS 2 installation to get started.

Install dependencies

OpenCV3+ is a must to install, please refer to the official installation guide from OpenCV Tutorials Since ROS 2 uses Python 3, please make sure that python3-numpy is installed, or install like this:


sudo apt install python3-numpy


The cv_bridge python backend still has a dependency on python boost (equal or higher than 1.58.0), and install them as follows in Ubuntu:


sudo apt install libboost-python-dev


Build and Test

Fetch the latest code and build


cd <YOUR_ROS2_WORKSPACE>/src
git clone https://github.com/ros-perception/vision_opencv.git -b ros2
cd ..
colcon build --symlink-install


Run the tests

Python tests have a dependency on OpenCV Python support. To install it:


sudo apt install python3-opencv


Next to prepare runtime environment and run tests:


source <YOUR_ROS2_WORKSPACE>/install/local_setup.bash
colcon test


Known issues

  • boost endian: remove boost endian APIs with standard C++ 11 or higher instead
  • Not tested with Windows or macOS environments so there may be issues building or running

Firstly, it assumes that the ros2 core has already been installed, please refer to ROS2 installation to get started if the ros2 core isn’t ready to use

Install dependencies

OpenCV3 is a must to install, please refer to the official installation guide from OpenCV Tutorials Since ros2 bases on python3, please make sure that python3-numpy is installed, or install like this:


sudo apt install python3-numpy


Now cv_bridge python backend still has dependency on python boost (equal or higer than 1.58.0), and install them as follows in Ubuntu 16.04:


sudo apt install libboost-python1.58.0
cd /usr/lib/x86_64-linux-gnu/ && sudo ln -s libboost_python-py35.so libboost_python3.so


Build and Test

Fetch the latest code and build


cd <YOUR_ROS2_WORKSPACE>
git clone https://github.com/ros-perception/vision_opencv.git
cd vision_opencv
git checkout ros2
colcon build --symlink-install


Run the tests

Python tests have dependency to opencv python support and install it:

pip3 install opencv-python


Next to prepare runtime environment and run tests:


source <YOUR_ROS2_WORKSPACE>/install/local_setup.bash
colcon test


Known issues

  • boost endian: remove boost endian APIs with standard C++ 11 or higer instead
  • Not verify with Windows and OS X environment and there may be building or running issues

cv_bridge

Introduction

cv_bridge converts between ROS 2 image messages and OpenCV image representation for perception applications. As follows:

cv_bridge overview

This ros2 branch initially derives from porting on the basis of ros kinetic branch

Installation

Firstly, it assumes that the ROS 2 core has already been installed, please refer to ROS 2 installation to get started.

Install dependencies

OpenCV3+ is a must to install, please refer to the official installation guide from OpenCV Tutorials Since ROS 2 uses Python 3, please make sure that python3-numpy is installed, or install like this:


sudo apt install python3-numpy


The cv_bridge python backend still has a dependency on python boost (equal or higher than 1.58.0), and install them as follows in Ubuntu:


sudo apt install libboost-python-dev


Build and Test

Fetch the latest code and build


cd <YOUR_ROS2_WORKSPACE>/src
git clone https://github.com/ros-perception/vision_opencv.git -b ros2
cd ..
colcon build --symlink-install


Run the tests

Python tests have a dependency on OpenCV Python support. To install it:


sudo apt install python3-opencv


Next to prepare runtime environment and run tests:


source <YOUR_ROS2_WORKSPACE>/install/local_setup.bash
colcon test


Known issues

  • boost endian: remove boost endian APIs with standard C++ 11 or higher instead
  • Not tested with Windows or macOS environments so there may be issues building or running

    • Add comprssed_imgmsg_to_cv2: Convert the compress message to a new image.
    • Add compressed image tests.

    - Add time to msgs (compressed and regular). add enumerants test for compressed image. merge the compressed tests with the regular ones. better comment explanation. I will squash this commit. Fix indentation fix typo mistage: from .imgmsg_to_compressed_cv2 to .compressed_imgmsg_to_cv2. remove cv2.CV_8UC1 remove rospy and time depndency. change from IMREAD_COLOR to IMREAD_ANYCOLOR.

    - keep the OpenCV error message. from: https://github.com/ros-perception/vision_opencv/pull/132#discussion_r66721013 add debug print for test. add case for 4 channels in test. remove 4 channels case from compressed test. add debug print for test. change typo of format. fix typo in format. change from dip to dib. change to IMREAD_ANYCOLOR as python code. (as it should). rename TIFF to tiff Sperate the tests one for regular images and one for compressed. update comment
