交流一个阳台自动关灯的问题【利用百度ai完美解决了】

evantalk

阳台的门装了门窗传感器，能实现开门自动亮灯，关门自动熄灯。但是有时候也有人在外面，要关门的情况，怎么办？
感谢萝卜大神共享的方案 @antsunzj，应用云台摄像头+ai人体分析判断人体是否存在    https://bbs.hassbian.com/thread-8097-1-1.html

原理就是通过摄像头截图，上传百度ai，百度“人流量统计”能从图片中识别出有多好个人，如果人数为0可以关灯
正好我阳台有海康威视的摄像头，完美解决了，过程中遇到几个坑跟大家分享一下：

1，新款的摄像头截图url需要摘要认证（用户名和密码），这个用node-red也是可以解决的



2，为了防止人走到边缘误判，可以检查2遍

可以考虑加个人体传感器，不过目前的人体传感器很多都是被动式的，静止不动的话就检测不到

georgewu57

这个时候就需要一个人体传感器了！

用人体传感器的话，要配置等待一段时间没检测到人体活动后关灯，否则很容易误关。这样感觉不太完美，人都进来了，灯还亮着

加个人体传感器，位置选得好一点，延时关闭配置长一点，可以做到几乎不误关。就是会觉得有点不完美，有时候人进来，接受不了灯还亮着就手动关一下，那天自动化就当保底了，至少忘关了也不会一直开着。

其实延时这种做法也是有好处的，可以避免传感器处于临界状态时灯频繁开关

我家要進入後陽台前需經過廚房
所以設計為人體感應只負責開燈, 廚房燈關閉時一併關後陽台燈
