如何为 python 安装 opencv 2.9?

如何为 python 安装 opencv 2.9?

我遇到了与描述完全相同的问题帖子中有人建议你升级到 opencv 2.9 版。我想知道怎么做?我安装了现在的版本,方法是

sudo apt-get install python-opencv

另外,我如何检查我现在运行的是哪个版本?我在使用 Ubuntu 13.10

编辑:

经过 girardengo 的回答,我知道我使用的是 2.4.5 版本,谢谢你!

答案1

在安装 OpenCV 开发版本之前,我建议使用此代码来设置捕获大小(从您发布的链接我假设您正在使用 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(今天的 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

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__

如果你想安装最新的 opencv 开发版本,你可以按照 opencv 官方文档的说明进行操作这里
