|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- 第二步:创建虚拟环境
|
|

|
|
```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
|
|
|
|
```
|
|
|
|
|
|

|
```shell
|
2021-12-29 16:47:23 +08:00
|
|
|
|
pip install -r ./requirements.txt -U # 安装OpenCV Webcam脚本
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

#### :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
|
|
|
|
```
|
|
|
