如何为Python安装opencv 2.9?


23

我遇到了与帖子中所述完全相同的问题,答案中的某人建议您升级到opencv版本2.9。我想知道怎么做?我通过执行安装了现在拥有的版本

sudo apt-get install python-opencv

另外,如何检查我现在正在运行的版本?我在Ubuntu 13.10上

编辑:

girardengo回答后,我知道我的版本是2.4.5,谢谢!


我可以知道如何键入“ version ”命令吗?

在安装OpenCV的开发版本之前,建议使用以下代码来设置捕获大小(从您发布的链接中假设我使用的是python):

import cv2

cap = cv2.VideoCapture(device_no)
cap.set(cv2.cv.CV_CAP_PROP_FRAME_WIDTH, width)
cap.set(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT, height)

要安装opencv的开发版本(今天为3.0.0-dev),请按照以下步骤操作:

cd $HOME
mkdir opencv_src
cd opencv_src/
git clone https://github.com/Itseez/opencv.git
cd opencv/
mkdir release
cd release/
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install

我尝试了您建议的命令,但这些命令不适用于我的罗技c910相机。我现在正在编译/安装最新版本,然后查看是否有所不同。谢谢

很奇怪,我有一台C920,使用opencv 2.4.5(默认的13.10版本)可以正常工作。您可以在此处

它没有与开发:(我会记住这解决,并张贴有关该错误消息我得到一个新的问题的工作。

嗨,evan54,很好奇-您使用的是Mac吗?另外,您是否根据上述说明安装了2.9或3.0?如果您在python中使用过opencv 3.0,您是否仍将其称为cv2?

有时您必须链接模块cd ~/.virtualenvs/cv/lib/python2.7/site-packages/ && ln -s /usr/local/lib/python2.7/site-packages/cv2.so cv2.so

打开终端,然后启动python interpeter:

python

然后,导入opencv:

import cv2

最后,打印版本:

cv2.__version__

如果要安装opencv的最新开发版本,则可以从此处按照opencv官方文档的说明进行操作
