[Support]: Counting cars in a static image during set interval

[danodemano]

Describe the problem you are having

I hope this is the right place to ask and I assume the answer is no but I'm in search of a solution and since Frigate is already up and running with a Coral TPU I'd like to leverage that if possible.

My state has public camera feeds for various state routes and freeways. One particular interchange I pass through a lot is under construction and traffic fluctuates a lot. I would love to have this as a "car count" sensor in Home Assistant so I can determine if I go that way or not. I already have the Frigate/MQTT/HA integration working.

Hopefully that makes sense. Here is a link to the camera feed I'm hoping to use. I'd like to pull that image every 15-30 seconds and count the cars then pass that to HA. https://itscameras.dot.state.oh.us/images/CMH/I-71_at_US-36.jpg

Thanks so much!

The Frigate HA integration provides a sensor.<camera_name>_<object_name>_count sensor for each camera and object that shows the number of objects of a type currently in the frame. That sensor should get you what you need.

Thanks for that. I guess the rest of the puzzle though how would I go about grabbing that image every say 30 seconds and processing it for vehicles? Can a static image even be used as a camera?

is there a reason why more frequent updates would be a problem?

[danodemano]

More frequent updates wouldn't be a problem at all, just wasn't sure if that would add too much load to anything. Currently with 12 cameras:

Inference Speed: 27.96 ms
CPU: 55.5%
