当我运行python代码时
import numpy as np
import cv2
import matplotlib.pyplot as plt
img1 = cv2.imread('/home/shar/home.jpg',0) # queryImage
img2 = cv2.imread('/home/shar/home2.jpg',0) # trainImage
# Initiate SIFT detector
orb = cv2.ORB()
# find the keypoints and descriptors with SIFT
kp1, des1 = orb.detectAndCompute(img1,None)
kp2, des2 = orb.detectAndCompute(img2,None)
# create BFMatcher object
bf = cv2.BFMatcher(cv2.NORM_HAMMING, crossCheck=True)
# Match descriptors.
matches = bf.match(des1,des2)
# Sort them in the order of their distance.
matches = sorted(matches, key = lambda x:x.distance)
# Draw first 10 matches.
img3 = cv2.drawMatches(img1,kp1,img2,kp2,matches[:10], flags=2)
plt.imshow(img3),plt.show()
我得到了这个错误:
AttributeError: 'module' object has no attribute 'ORB'
我使用的是python3和opencv3

我还发现了这个。我检查了cv2
模块的实际内容,发现是ORB_create()
而不是ORB()
使用这条线
orb = cv2.ORB_create()
而不是orb = cv2.ORB()
,它将会工作。
在Windows上的Python3.4、OpenCV 3上使用OpenCV测试数据集box.png
和box_in_scene.png
进行了验证,结果如下。请注意,您必须将None
outImg
放在行img3 = cv2.drawMatches(img1,kp1,img2,kp2,matches[:10], flags=2)
