树莓派USB摄像头拍照
可以使用Python中的Picamera库来实现这个功能,以下是示例代码:
1. 导入Picamera库
```
import time
import picamera
```
2. 等待2秒
```
time.sleep(2)
```
3. 初始化摄像头
```
with picamera.PiCamera() as camera:
```
4. 设置摄像头参数(如分辨率、帧率、白平衡等)
```
camera.resolution = (1920, 1080)
camera.framerate = 30
camera.awb_mode = 'auto'
```
5. 拍照并保存图片
```
camera.capture('image.jpg')
```
完整代码:
```
import time
import picamera
time.sleep(2)
with picamera.PiCamera() as camera:
camera.resolution = (1920, 1080)
camera.framerate = 30
camera.awb_mode = 'auto'
camera.capture('image.jpg')
```
希望能够帮到您。
