#### :white_check_mark: 方法一Linux Shell安装开发版
2021-12-29 16:47:23 +08:00
2022-01-16 17:14:22 +08:00
- 第一步:克隆项目
```shell
git clone https://gitee.com/CV_Lab/opencv_webcam.git # 克隆项目
```
- 第二步:创建虚拟环境
2021-12-29 16:47:23 +08:00
```shell
# 创建conda虚拟环境以python 3.8为例
2022-01-23 21:45:26 +08:00
conda create -n ows python==3.8 # 虚拟环境名称为ows
conda activate ows # 激活虚拟环境
2022-01-16 17:14:22 +08:00
```
- 第三步:安装脚本
```shell
2021-12-29 16:47:23 +08:00
pip install -r ./requirements.txt -U # 安装OpenCV Webcam脚本
```
2022-01-07 13:29:26 +08:00
#### :white_check_mark: 方法二pip 快速安装PyPi版
2021-12-29 16:47:23 +08:00
2022-01-23 21:45:26 +08:00
- 第一步创建ows虚拟环境参见方法一
2021-12-29 19:56:07 +08:00
- 第二步执行pip指令
```shell
2022-01-24 10:50:30 +08:00
pip install opencv-webcam-script==0.4.0
2021-12-29 19:56:07 +08:00
```
- 第三步编写python程序
```python
from opencv_webcam.opencv_webcam import webcam_opencv
2022-01-06 21:33:05 +08:00
# 例举两个功能
webcam_opencv() # 常规调用
webcam_opencv(is_autoSaveFrame=True) # 自动保存帧
2022-01-24 08:08:00 +08:00
webcam_opencv(is_autoSaveFrame=True, is_compress=True) # 压缩帧
2021-12-29 16:47:23 +08:00
```
2021-12-31 23:38:11 +08:00
2021-12-31 23:54:16 +08:00

2022-01-23 20:11:17 +08:00
xhost +local:root # 允许root用户访问正在运行的X服务器重要
2022-01-24 16:19:40 +08:00
sudo docker run --name=ows --ipc=host -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY --device=/dev/video0:/dev/video0 zengdockerdocker/opencv-webcam-script:v0.4 # 创建名称为ows的容器
2021-12-31 23:38:11 +08:00
```
2022-01-16 17:14:22 +08:00

2021-12-31 23:38:11 +08:00
2022-01-16 17:14:22 +08:00
```shell
python3 opencv_webcam.py # 运行脚本程序
python3 opencv_webcam.py -isasf # 自动保存帧
2022-01-24 07:41:31 +08:00

sudo docker cp 容器名称:容器目录 本机宿主目录
sudo docker cp ows:/usr/src/app/WebcamFrame /home/用户名 # 举例
2022-01-25 20:40:21 +08:00
# 退出ows容器
exit
# 启动并进入ows容器
sudo docker start ows
sudo docker exec -it ows /bin/bash
