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

问题描述

我正在尝试获取两个立体图像的深度图.我已经从

I am trying to get the depth map of two stereo images. I have taken the code from this documentation.

我收到以下错误:

Traceback (most recent call last):
  File "depth.py", line 9, in <module>
    stereo = cv2.createStereoBM(numDisparities=16, blockSize=15)
AttributeError: 'module' object has no attribute 'createStereoBM'

我的代码是:

import numpy as np
import cv2
from matplotlib import pyplot as plt

imgL = cv2.imread('tsukuba_l.png',0)
imgR = cv2.imread('tsukuba_r.png',0)

stereo = cv2.createStereoBM(numDisparities=16, blockSize=15)
disparity = stereo.compute(imgL,imgR)
plt.imshow(disparity,'gray')
plt.show()

我进入了Python行解释器，并编写了以下代码:

I entered the Python line interpreter, and wrote the following code:

import cv2
help(cv2)

在cv2中没有名为createStereoBM的函数.

There is no function called createStereoBM in cv2.

顶部提供的链接中的代码是否错误?我在Ubuntu 12.04中使用Python 2.7.3. 该代码是否可能适用于Python 3及更高版本?

Is the code wrong in the link provided at the top? I am using Python 2.7.3 in Ubuntu 12.04. Is it possible that the code is meant for Python 3 and above?

请帮助.

推荐答案

请改用此功能

stereo = cv2.StereoBM(cv2.STEREO_BM_BASIC_PRESET,ndisparities=16, SADWindowSize=15)
