根据提供的引用,调节摄像头焦距可以使用cv2库中的函数。引用中提到可以使用以下代码弹出一个设置界面,在这个界面中找到合适的焦距:
```python
m_capture_0.set(CV_CAP_PROP_SETTINGS, 1)
```
然而,引用指出在Mac下的OpenCV并没有实现CV_CAP_PROP_SETTINGS和CV_CAP_PROP_FOCUS,同时V4l包也没有在Mac下的实现,因此在Mac下貌似不能设置第三方摄像头的焦距。但是,有些人可以通过调用USB的底层函数实现设置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
