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
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 summarizedVehicle Colors
- A set off all observed colors, each score summarizedHuman Upper Clothing Colors
- A set off all observed colors, each score summarizedHuman Lower Clothing Colors
- A set off all observed colors, each score summarizedObservations
- Represents the object track as a list all of all observations of the recorded of the object, including a bounding box for each observationImage
- The best image snapshot of the objectMin and Max speed
- The min and max speed of the objectStart Time
- Start time of the track, when the object was first detectedEnd Time
- End time of the track, when the object was last observedDuration
- The duration of the track, i.e. elapsed time between first and last observationEnd 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.
