Python-OpenCV基本操作方法详解
cv2.imread函数是用来读取图像的,而不是读取视频。要读取视频,可以使用cv2.VideoCapture函数。这个函数可以从视频文件或摄像头中读取图像。例如,你可以使用以下代码读取视频文件:
```python
cap = cv2.VideoCapture("01.mp4")
```
其中"01.mp4"是视频文件的路径。你也可以使用数字0来代表摄像头设备,例如:
```python
cap = cv2.VideoCapture(0)
```
这样就可以从摄像头中读取图像了。希望这个回答对你有帮助。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
