||
#### :white_check_mark: 方法一：Linux Shell安装（开发版）
|
||
|
||
```shell
|
||
# 克隆项目
|
||
git clone https://gitee.com/CV_Lab/opencv_webcam.git
|
||
# 创建conda虚拟环境，以python 3.8为例
|
||
conda create -n ow python==3.8 # 虚拟环境名称为ow
|
||
conda activate ow # 激活虚拟环境
|
||
pip install -r ./requirements.txt -U # 安装OpenCV Webcam脚本
|
||
```
|
||
|
||
|
||
|
||
#### :white_check_mark: 方法二：pip 快速安装（API版）
|
||
|
||
- 第一步：创建ow虚拟环境，参见方法一
|
||
- 第二步：执行pip指令
|
||
|
||
```shell
|
||
pip install opencv-webcam-script
|
||
```
|
||
|
||
- 第三步：编写python程序
|
||
|
||
```python
|
||
from opencv_webcam.opencv_webcam import webcam_opencv
|
||
# 直接使用webcam_opencv
|
||
webcam_opencv(device_index=0, quit_key='q', is_autoSaveFrame=False, frame_saveDir='./webcam', frame_nSave=1, is_headSaveFrame=False, frame_capKey='a', is_resizeFrame=False, resize_frame=[640, 480], resizeRatio_frame=1.0)
|
||
```
|
||
|
||
|
||
|
||
#### :white_check_mark: 方法三：docker 镜像安装（容器版）
|
||
|
||
```shell
|
||
sudo docker pull zengdockerdocker/opencv-webcam-script:v0.1 # 镜像拉取
|
||
|
||
xhost +local:root # 配置xhost
|
||
sudo docker run --ipc=host -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY --device=/dev/video0:/dev/video0 zengdockerdocker/opencv-webcam-script:v0.1 # 进入容器
|
||
python3 opencv_webcam.py # 运行脚本程序
|
||
```
