python – OpenCV找不到ORB

在我的previous question中,我了解到必须安装opencv-contrib才能将OpenCV Python与外部模块(如SIFT)一起使用.但是,在我的项目中,我想使用ORB或类似的东西. cv2.ORB()不起作用,cv2.xfeatures2d.ORB_create()或任何其他命令的凝集也不起作用.

据了解,OpenCV的Python API文档相当差.

如何使用ORB匹配OpenCV Python中的功能?

MWE

#!/usr/bin/python2.7
import numpy as np
import cv2
from matplotlib import pyplot as plt

img = cv2.imread('smallburger.jpg',0)

# Initiate STAR detector
orb = cv2.ORB()

# find the keypoints with ORB
kp = orb.detect(img,None)

# compute the descriptors with ORB
kp, des = orb.compute(img, kp)

# draw only keypoints location,not size and orientation
img2 = cv2.drawKeypoints(img,kp,color=(0,255,0), flags=0)
plt.imshow(img2),plt.show()

CLI输出:

Traceback (most recent call last):
  File "./mwe.py", line 9, in <module>
    orb = cv2.ORB()
AttributeError: 'module' object has no attribute 'ORB'
