3D Image Layer Navigation#
The RadarImager can acquire 3D images of objects moving on a conveyor belt. These 3D images consist of a stack of layers, each representing a different depth in the z-direction. Navigating through these layers allows you to view specific details of the object at different depths.
Navigating through the 3D Image Layers#
Prerequisite
- The RadarImager is setup and the first image is generated.
- The parameter
distanceZToDeepestLayerOfInteresthas been configured appropriately.
To explore the object at different depths, you can navigate through the 3D image layers by selecting
the desired layer using the parameter layerSelection.indexedPositions:
The animation above shows different layers of a pan. The upper layers reveal the handle of the pan, while the lower layers display the bottom of the pan, along with a leaflet and a cord resting on it.
Matching Layers with Depth
Refer to the configuration reference for the parameter layerSelection.indexedPositions
to understand how many layers can be selected and which layer corresponds to which depth.
Finding the layer of interest#
To identify the layer of interest, you can navigate through the layers using the normalization kind
´normalAbs.kind set to LAYER.
This mode normalizes each layer based on its own minimum and maximum values, making it easier to analyze individual layers.
Alternatively, you can use the GLOBAL mode for ´normalAbs.kind,
which normalizes all layers based on the minimum and maximum values across all selectable layers.
This mode is particularly useful for quickly identifying the layer of interest for high-reflective objects.
A recommended strategy is to start with the GLOBAL mode to get an overview of high-reflective layers
and then switch to the LAYER mode for a more detailed analysis.
Below is an example illustrating the difference between the LAYER normalization kind (left) and the GLOBAL normalization kind (right):
