Zone Types
Zones are the main method to configure the on-device processing pipeline. Each zone analyzes particular input data (e.g., the enclosed point cloud or detected objects) using specific algorithms. Further, a set of zone-specific parameters can be configured to adjust behavior and output.
The following zone types are available:
-
Exclusion Zone: Excludes a section of the scene from processing
-
Occupancy Zone: Determines if the area is free or occupied
-
Security Zone: Generates alarms when the zone is penetrated
-
Volume Zone: Measures the enclosed volume
Parameters
All zone types share common parameters. Not every parameter is exposed through the WebGUI. To see the full list of parameters look at the configuration API definition.
General
- Name
-
The name of the zone. Can be set to an arbitrary string which helps to recognize it in the 3D scene.
- Disabled
-
This boolean property can be used to disable the particular zone for processing. When zones are temporarily not required this flag can be used.
Instead of deleting a zone when it is not required just disable it by setting this parameter to
true. The zone appears greyed out in the viewer of the WebGUI when disabled.
Geometric
- Shape
-
A zone is represented as a rectangular cuboid that serves as an enclosing volume around a region of interest in the scene. It is defined by its three-dimensional geometric parameters:
-
Position: Distance from the origin to the zone center point: \((p_x,p_y,p_z)\)
-
Orientation: Rotation with respect to origin orientation: \(R\)
-
Dimension: Size of the zone edges in x, y, and z direction: \((d_x,d_y,d_z)\)
