ArUco Python wrappers
Project description
python-aruco
SWIG generated Python wrappers for ArUco library. Works with OpenCV Python module cv2 resp. numpy array data types.
Tested on Linux Mint 19 x86_64, OpenCV 4.1.0, ArUco 3.1.12 Python 3.6.9 and NumPy 1.18.0
Installation via pip
- Install / compile OpenCV with Python2 support
- Install / compile ArUco 3.1.12
- run
pip3 install aruco
Installation Python3 via CMake
- Install / compile OpenCV with Python2 support
- Install / compile ArUco 3.1.12
- Install swig3:
sudo apt-get install swig3.0
for Debian/Ubuntu like systems. On 14.04 and other older systems you will need to go to "Software Sources" and check backports in the Updates tab, and reload before installing. - Install NumPy
pip3 install numpy
(maybe you already need it for OpenCV Python support) or install via system package manager. - Build the Python wrapper:
- Create a new directory
build
in this project:mkdir build && cd build
- Run CMake to configure the project:
cmake ..
- Run make to build the wrappers:
make
- Create a new directory
- The built package is now located in
python/dist/
, you can install it via pip:pip3 install python/dist/*.whl
Test
example video
open a prompt in example/
and run: python ./example.py
or python3 ./example.py
fractal marker example
open a prompt in example/
and run: python ./fractal.py
or python3 ./fractal.py
If the Python doesn't find some shared objects, add the library location to LD_LIBRARY_PATH:
export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
Problems
I just tested some basic functions with example/example.py
/ example/fractal.py
.
Please report errors and problems.
- Some return value templates like
std::vector<Point3f>
don't work yet (e.g. formarker.get3DPoints()
)
Thanks
- Thanks to Mizux for the great cmake-swig example project
