我最後把系統改成64位元再照著上面的步驟重複一次就可以使用了
真的非常感謝您!!

这个问题放一边，先不管他。
你这个如果系统是32位的

1. 先看看/lib/modules/6.1.21-v7l+下面有没有build。
2. 如果有，改一下cam_drv_src\rpi-6.1.y\Makefile，手动指定一下KERNEL_ROOT

KERNEL_ROOT=/lib/modules/6.1.21-v7l+/build 

sudo dpkg -i raspberrypi-kernel-headers_1.20230405-1_arm64.deb

uname -a

ls /lib/modules/

可以幫助我嗎?謝謝!

錯誤內容為:
[ WARN:0@0.404] global /home/pi/opencv/modules/videoio/src/cap_gstreamer.cpp (2401) handleMessage OpenCV | GStreamer warning: Embedded video playback halted; module v4l2src0 reported: Device '/dev/video0' does not support 1:4:7:1 colorimetry

請問我是哪裡做錯了嗎?
謝謝您!
