Question

我在运行$ sudo apt-get install python-opencv的python中安装opencv并成功安装。但是在运行此代码时

import opencv
import opencv.highgui
import time
import commands

def get_image():
    image = opencv.highgui.cvQueryFrame(camera)
    return opencv.adaptors.Ipl2PIL(image)

camera = opencv.highgui.cvCreateCameraCapture(-1)

while 1:
    image = get_image()
    image.thumbnail((32, 24, ))
    image = tuple(ord(i) for i in image.tostring())
    x = int((int((max(image) / 256.0) * 10) + 1) ** 0.5 / 3 * 10)
    cmd = ("sudo su -c 'echo " + str(x) +
        " > /sys/devices/virtual/backlight/acpi_video0/brightness'")
    status, output = commands.getstatusoutput(cmd)
    assert status is 0

得到关注错误

$ python bright.py 
Traceback (most recent call last):
  File "bright.py", line 1, in <module>
    import opencv
ImportError: No module named opencv

你能帮我吗？

Answer 1

您应该导入cv2而不是opencv，也没有highgui。您可能需要查看docs

Answer 2

要安装opencv for python，您需要命令
$ pip install opencv-python
要导入它以便在应用程序中使用，调用包的导入是
import cv2

ImportError：在Ubuntu 14.04中安装python-opencv后没有名为opencv的模块
