Nx Meta’s newest patch, Meta R4, is here! This Nx Meta patch is a third preview and sneak peek of the changes coming in the next major release (v5.0). The Meta R4 patch – Meta 220.127.116.11871 R4 – was built with a focus on enhanced Analytic plugin development, interface functionality, and a remodeled Rest API.
With Meta R4, developers can expect a lot of “new”, including:
Read on to learn more.
Nx Meta R4 has a completely new Rest API that has been built based on the widely-used Open API standard for open collaboration among developers.
The updated API documentation is now split into 2 sections – the latest current API (new CRUD-based REST conformant API) and a legacy / deprecated API (v4.2 or earlier).
More information regarding each section can be found in the new preamble of the API Documentation page.
The new Rest API (available in Nx Meta now and in the next major release of Powered by Nx products / Nx Witness VMS) includes:
On the Metadata SDK side of things, Meta R4 brings about 4 new improvements:
Advanced Search for Objects
A new Advanced Search Window interface has been added in Desktop Client for enhanced Analytics Object search. The new interface allows for the easy search of objects filtered by selected attributes and object types from the updated Object Detection Taxonomy (see below).
Taxonomy for Object Detection
Object Detection Taxonomy has been updated with new methods of declaring object types and attributes with the ability to override basic types or create new object types.
Analytics Object Detected Event
A new “Analytics Object Detected” Event has been introduced to the Rules Engine. The new addition extends system automation capabilities, giving developers the ability to refine object detection based on specific object types and attributes (i.e. Mask, Glasses, etc) and configure system reactions to the detection of those specific object types and attributes in supporting cameras.
New analytics sub-plugins are now available as part of the Metadata SDK. Originally demonstrated in the `object_detection` sub-plugin, the below plugins have been broken down into multiple sub-plugins to demonstrate specific analytics features and how to develop them.
New Object Types for Overlays and Telemetry/Tracker Data
New object types have been added for implementing Overlay objects (liveOnly) and Trackers/Telemetry (nonIndexable).
