macでOpenCV2.3.1＋Python
OpenCVをPythonで使いたい！！ってことで入れてみました。
事前準備
前OpenCVは入れていたので、いろいろ省略。
ビルド
いつもはcmake-guiを使うんだけど、PythonのPATHの設定方法がいまいちわからなかったので、コマンド実行しました。
＊ここを参考にさせて頂きました

cmake
こんな感じになりました。

よし、PythonのPATHがちゃんと通ったぞっ（＾－＾）
make & make install
普通にmakeしましょう。
しかしビルド早いなぁー。昔は１時間ぐらいかかってた気がするー
実行してみる
とりあえずimport
$ python Python 2.7.2 (default, Jan 7 2012, 15:15:33) [GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import cv2 Segmentation fault: 11
あれれ？動かない^^;

うん、Pythonあるぞ？
。。。
あぁ、PATHか。
ということで、PATHを通す
export PYTHONPATH=$PYTHONPATH:/usr/local/opencv/lib/python2.7/site-packages/
動いた(・∀・)
OpenCV同梱のPythonのサンプルを動かしてみる
とりあえず、カメラでも動かしてみよう。
import cv2.cv as cv
import time
cv.NamedWindow("camera", 1)
capture = cv.CaptureFromCAM(0)
while True:
img = cv.QueryFrame(capture)
cv.ShowImage("camera", img)
if cv.WaitKey(10) == 27:
break
これを実行
python camera.py
なんか画面に顔がー！！誰だー！
あ。自分か(´・ω・｀)
ということでおしまい！
