Metropolis Microservices for NVIDIA Jetson - Metropolis Analytics Microservices
The Analytics Microservice takes the inference metadata and processes it to generate alerts and metrics. These metrics can be obtained by a client app via the Web API. It enables users to obtain metrics of the environment surrounding a camera.
Behaviour Analytics modules
FOV
This metric uses the full field of view of the camera to track and count people in it. With that, it can generate alerts and time-based metrics. The following alerts can be set:
- Occupancy Counts
- Occupancy Alerts
- Occupancy Alter Rules
- Increment Alert
- Occupancy Alert
- Occupancy Switch Alert
The API documentation for FOV metric is here.
Trip-wire
A line can be set so an event is sent every time a person moves through said line. It provides time-based alerts and metrics. The following alerts can be used:
- Crossing Count
- Crossing Alerts
- Flowrate Alerts
The API is documented here.
ROI
This is similar to the FOV metrics, but using a set region of the camera view, not all of it. The rules that can be set are:
- Increment Alert
- Occupancy Alert
- Occupancy Threshold switch
The documentation for the ROI API is here.
