从imshow开始运行OpenCV脚本 [英] Run OpenCV script on start with imshow

问题描述

我在Raspberry Pi上运行一个OpenCV/python脚本，该脚本读取相机并在连接到Pi的RCA监视器上显示流.

I have an OpenCV/python script running at my Raspberry Pi which reads the camera and shows the stream on the RCA monitor connected to the Pi.

现在，我希望在引导时加载脚本.我已经尝试了cronjob @ reboot，/etc/rc.locale，/etc/profile和〜/.bash_profile.

Now I want the script to be loaded on boot. I already tried a cronjob @reboot, the /etc/rc.locale, /etc/profile and ~/.bash_profile.

我看到相机的红灯每次都打开，但不会显示图像.有运行脚本的解决方案吗? (我没有连接任何外部输入设备)

I see the red light of the camera turning on every time, but the image won't be shown. Is there any solution to run the script? (I have no external input devices connected)

谢谢！

I know its quite an old thread, but I thought you might be still interested in a solution that worked for me. Hopefully, that can help you as well:

简而言之:您最有可能在DISPLAY/XAUTHORITY环境变量上遇到问题.

In short: You most likely have problems with the DISPLAY / XAUTHORITY environment variable.
