Track summary

The Track Summary module summarizes tracks generated by the Fusion Tracker module.

Since a track summary instance is dependent on data from a Fusion Tracker module instance, any configuration on the Fusion Tracker module can affect this module's output. For example, features such as

• Best Snapshot
• Geographic Coordinates

on the Fusion Tracker module instance will also effect what can be summarized using this module.

Instances

A device is preconfigured with a fixed number of instances of this module type.

There is one instance of the track summary module for each instance of the Fusion Tracker module.

Function

This module provides data organized as an object's track summary, that includes the track itself as well as some aggregate property data from the object's state.

Properties

• Classes - A set off all plausible classes, each score summarized
• Vehicle Colors - A set off all observed colors, each score summarized
• Human Upper Clothing Colors - A set off all observed colors, each score summarized
• Human Lower Clothing Colors - A set off all observed colors, each score summarized
• Observations - Represents the object track as a list all of all observations of the recorded of the object, including a bounding box for each observation
• Image - The best image snapshot of the object
• Min and Max speed - The min and max speed of the object
• Start Time - Start time of the track, when the object was first detected
• End Time - End time of the track, when the object was last observed
• Duration - The duration of the track, i.e. elapsed time between first and last observation
• End Reason - Indicates why a track ended

Output protocols

This module's output can be retrieved using a variety of methods. Depending on what method is used the data can be sent on different formats, below is a full list of ways to retrieve the output.

Protocol	Name	Format	Guide
MQTT	com.axis.consolidated_track.v1.beta	ADF Consolidated Track	scene metadata over MQTT
Message Broker	com.axis.consolidated_track.v1.beta	ADF Consolidated Track	Build an ACAP that consumes scene metadata

Limitations

• If 10 minutes have passed, the track is ended prematurely to conserve memory and a new track is started with a new id.
• There is no way of connecting summarized object tracks back to object produced by Fusion Tracker module.
