These are OpenCV bindings for SBCL. They do not promise to be complete, though eventually I hope to have fairly complete coverage of OpenCV functionality. This package depends on the cffi package and libffi. I use Quicklisp to set up my Lisp environment.
This package is known to work in the following configurations.
- Mac OS 10.6, sbcl 1.0.45 (MacPorts), OpenCV 2.2 (MacPorts)
- Ubuntu 10.10 (64-bit), sbcl 1.0.40, OpenCV 2.1
If you have gotten cl-opencv to run with some other combination of OS and software versions, please let me know.
- Install OpenCV from MacPorts:
port install opencv - Install libffi from MacPorts:
port install libffi - In your lisp environment, make sure that cffi is available. In
Quicklisp you would just do
(ql:quickload "cffi"). - Run
makeandsudo make installin the top-level directory to build and install the glue code library.
- Install OpenCV from the repos:
sudo apt-get install libhighgui-dev. - Install libffi from the repos:
sudo apt-get install libffi - In your lisp environment, make sure that cffi is available. In
Quicklisp you would just do
(ql:quickload "cffi"). - Run
makeandsudo make installin the top-level directory to build and install the glue code library.
If CFFI has problems loading the library, be sure that:
- your lisp and your OpenCV library are both 32 bit or both 64 bit; and
- if you installed OpenCV to a non-standard location, you might try
adding that path to
cffi:*foreign-library-directories*.
Different camera support different resolutions and framerates. The tests assume a camera capable of about 30 fps at 640x480. Adjust the values at the top of test.lisp to match your camera. A program like VLC can help you determine those.
