I am working on a Coral module that will work with custom models.
That would be amazing, good luck.

I'm looking forward to use them. The default models on mine strangely take 100-200ms to process. It could be because I run blueiris as a VM in Hyper-v and passthrough the pci-e coral directly to the VM, but I was expecting a bit better performance. It is a Ryzen 5800U cpu running it.

Hi Mike,

Curious how you're coming with Coral AI and custom models? I just need to detect people and vehicles. I have a Nvidia 1030 GPU but would consider switching to Coral if much faster?

Thanks,

David

I tried again today with a coral tpu wif m2. Installed without issues. CPAI Dashboard worked with the coral module and achieved inference speeds of 7-9ms on cpai.

But from the Blueiris side - no triggers would trigger the coral to analyise the snapshots. Swapped the module back to GPU and working again.

What am I missing? Some on the BI side? Some config setting in the AI of BI?
Or are the the models of the current cpai module tpu(tf-lite) just not working with BI?

Thanks

I'm not an expert, but I'll try to help. From what I understand, the software movement detection from Blue Iris or the camera own movement sensor via ONVIF will tell Blue Iris to pass that to AI to do the object detection. Just to make it clear, coral does not trigger any detection, it just identifies what is on the image from a trigger that Blue Iris created, and passed the image for it to analise. BI then has configuration to confirm/cancel the detection based on its configuration under the AI tab for each camera.

For example, my decent cameras all trigger ONVIF alerts to BlueIris, then on alert tab of the camera I have the AI configuration as follow:

Also make sure it is using the correct port, codeproject ai changed its port on recent updates:
