使用VS2008编译OpenCV2.2,在F:/CV/OpenCV/OpenCV-2.2.0/Build/Python2.6/Lib/site-packages目录下,
生成cv.lib和cv.pyd两个文件。
1、 将F:/CV/OpenCV/OpenCV-2.2.0/Build/bin添加到系统环境变量中;
2、 将cv.lib 和 cv.pyd文件拷贝到python安装路径下的E:/programs/Python2.6.5/Lib/site-packages目录中;
然后即可以使用OpenCV的python rapper了。/(^o^)/~
下面以提取surf特征,并绘制到原图上为例:
from numpy import *
import cv
img = cv.LoadImage('F:/removed_haze.jpg')
gray = cv.CreateImage(cv.GetSize(img), 8, 1)
cv.CvtColor(img, gray, cv.CV_BGR2GRAY)
(keys, descs) = cv.ExtractSURF(gray, None, cv.CreateMemStorage(0), (0, 300, 3, 1))
for key, desc in zip(keys, descs):
r = key[2]
cv.Circle(img, key[0], r, cv.RGB(255,255,0), 1, cv.CV_AA)
angle = key[3]
sx = key[0][0]
sy = key[0][1]
ex = sx + r * cos(angle/360 * pi)
ey = sy + r * sin(angle/360 * pi)
cv.Line(img, (sx,sy), (ex, ey), cv.RGB(0, 255, 0), 1, cv.CV_AA)
cv.ShowImage('test', img)
cv.WaitKey(0)
