AttributeError:“模块"对象没有属性"ORB" [英] AttributeError: 'module' object has no attribute 'ORB'

问题描述

当我运行python代码时

when I run my python code

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

I am using python3 and opencv3

推荐答案

我也发现了这一点.我检查了cv2模块的实际内容，发现是ORB_create()而不是ORB()

I found this also. I checked the actual contents of the cv2 module and found ORB_create() rather than ORB()

使用线路

orb = cv2.ORB_create()

代替orb = cv2.ORB()，它将起作用.

使用OpenCV测试数据集box.png和box_in_scene.png在Windows 3.4上的Python 3.4，OpenCV 3上进行了验证，并具有以下结果. 注意 ，您还必须在img3 = cv2.drawMatches(img1,kp1,img2,kp2,matches[:10], flags=2)行中为outImg输入None.-请参见

Verified on Python 3.4, OpenCV 3 on Windows, using the OpenCV test data set box.png and box_in_scene.png with the following results. Note you have to put in None for outImg in the line img3 = cv2.drawMatches(img1,kp1,img2,kp2,matches[:10], flags=2) also - see my answer to your other question.
