Add an ArUcoScene
=================
An [ArUcoScene](../../argaze.md/#argaze.ArUcoMarkers.ArUcoScene) class defines ...
Besides, the [ArUcoCamera](../../argaze.md/#argaze.ArUcoMarkers.ArUcoCamera) class projects [ArUcoScenes](../../argaze.md/#argaze.ArUcoMarkers.ArUcoScene)'s layers into its own layers thanks to ArUco markers pose estimations made by its [ArUcoDetector](../../argaze.md/#argaze.ArUcoMarkers.ArUcoDetector).
## Add ArUcoScene to ArUcoCamera JSON configuration file
An [ArUcoCamera](../../argaze.md/#argaze.ArUcoMarkers.ArUcoCamera) instance can contains multiples [ArUcoScene](../../argaze.md/#argaze.ArUcoMarkers.ArUcoScene).
Here is an extract from the JSON ArUcoCamera configuration file with a sample where one scene is added:
```json
{
"name": "My FullHD camera",
"size": [1920, 1080],
...
"scenes": {
"MyScene" : {
"aruco_markers_group": "aruco_description.json"
},
"layers": {
"MyLayer": {
"aoi_scene": "aoi_description.obj"
}
}
},
"layers": {
"MyLayer": {}
}
...
}
```
Now, let's understand the meaning of each JSON entry.
### "MyLayer"
The name of the [ArUcoScene](../../argaze.md/#argaze.ArUcoMarkers.ArUcoScene). Basically useful for visualisation purpose.
### ArUco markers group
...
### Layers
...
### AOI scene
The [AOIScene](../../argaze.md/#argaze.AreaOfInterest.AOIFeatures.AOIScene) defines a set of 2D [AreaOfInterest](../../argaze.md/#argaze.AreaOfInterest.AOIFeatures.AreaOfInterest) registered by name.
