首先,我们直接编译opencv应该就有python的接口:/usr/local/lib/python3.5/dist-packages;发现有cv2.cpython-35m-x86_64-linux-gnu.so文件,说的直接拷贝到env下的site-packages,结果报错; 然后我们本身直接sudo apt-get install python-opencv安装的是直接可以使用的; sudo直接安装按系统默认的python2.7上:/usr/lib/...
cv2.imshow("Lena image",img)cv2.waitKey(0)cv2.destroyAllWindows() 在Python中运行结果如下: 显示图像 使用opencv-python读取本地视频 Opencv-python在线文档中有关于的Python示例代码:https://docs.opencv.org/4.9.0/dd/d43/tutorial_py_video_display.html 代码语言:javascript 代码运行次数:0 运行 AI代码...
🔥1. 安装 OpenCV 模块 OpenCV 已经支持 python 的模块了,直接使用 pip 就可以进行安装,命令如下: pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple some-package 💥2. OpenCV 基本使用 ️读取图片显示图像是 OpenCV 最基本的操作之一,imshow()函数可以实现该操作。如果使用过其他 ...
首先，我们需要安装Python环境及OpenCV模块，这里不再赘述了。安装OpenCV使用下面命令：pip install opencv-python 或 pip install opencv-python-headless 下面这个命令只安装不包含GUI的OpenCV版本。再者，我们需要准备一幅待识别人脸的图像。如下图：此外，如果你想进行人脸检测，还需要下载安装人脸识别模型。人脸识别模型...
pip install opencv-python pip install opencv-python==3.3.0.10 -i https://pypi.doubanio.com/simple 一、读入图像 使用函数cv2.imread(filepath,flags)读入一副图片 filepath:要读入图片的完整路径 flags:读入图片的标志 cv2.IMREAD_COLOR:默认参数,读入一副彩色图片,忽略alpha通道 cv2.IMREAD_GRAYSCALE:读入...
pip install opencv-python pip install numpy 1. 2. 安装numpy和opencv,如图cv是3.4.3版本,numpy是1.15.4版本, 然后我还下载了opencv-contrib-python,这个是扩展包,也用pip就能下载。 然后去看idea,然后可能会发现imread上提示:Cannot find reference ‘imread’ in ‘init.py’ | cv2 ...
