Add last_detection attribute? #30

Closed robmarkcole closed 5 years ago

robmarkcole commented 5 years ago

Add attribute to display the time of the last detection of an object? Alternatively we could place the timestamp in the processed image.

this would be helpful for things like cars - where motion is detected (say a tree moves in the wind), and there is a car in the driveway. Simple car > 0 logic would fire alerts all the time. However car new > car old would be useful, so only alerts if a new car is detected.

@jaburges deepstack cannot identify specific cars unfortunately

jaburges commented 5 years ago

no, but it can detect an increase in the number of cars compared to last value. So car on driveway = 1 (so car.old = 1) new car is detected alert is triggered as car.new > car.old

This would also prevent alerts constantly due to the "I see a car" when its been there the whole time.

robmarkcole commented 5 years ago

I don't know what you mean, the state of the sensor is the number of target objects identified. You also have the event image_processing.object_detected which is fired for each object detected.

This would be a nice idea for tracking recognised faces, but maybe should be on the person integration
