opencv-无法从raspberry pi上的摄像头捕获帧

OpenCV 依赖于V4L2(Linux视频)模块,因此请尝试在文件底部添加以下行 /etc/modules 重新启动你的覆盆子Pi。

bcm2835-v4l2

我的现在看起来像这样 总计 :

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

bcm2835-v4l2

Broadcom视频Linux 2版 (v4l2)驱动程序在所有后续重新引导时加载。
