AttributeError:'module'对象没有属性'ORB'

Question

当我运行我的python代码

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()

我收到此错误:

AttributeError: 'module' object has no attribute 'ORB' 

我正在使用python3和opencv3

Answer 1

我也找到了这个.我检查了cv2模块的实际内容ORB_create()而不是找到ORB()

使用该行

orb = cv2.ORB_create()

而不是,orb = cv2.ORB()它会工作.

在Python 3.4上验证,在Windows上使用OpenCV 3,使用OpenCV测试数据集box.png并box_in_scene.png获得以下结果. 注意你必须把None用于outImg该行img3 = cv2.drawMatches(img1,kp1,img2,kp2,matches[:10], flags=2)还-看到我的回答你的其他问题.
