## Apriltag detection
Allows to detect and get the pose out of CuImages.
They need to be 8bits and with high contrast (see the dynamic thresholding task).
### Configuration
In the Ron file you need to specify the tag family, the tag size and the camera intrinsics.:
```RON
tasks: [
(
id: "pos",
type: "cu_apriltag::AprilTags",
config: {
"tag_family": "tag16h5",
"tag_size": 0.14,
"fx": 1513.93,
"fy": 1513.93,
"cx": 946.84,
"cy": 557.819,
},
),
]
```
### Input
- `CuImage` (required): The CuImage to detect the apriltag on. It should be 8bits and with high contrast.
### Output
- `Pose`: The pose of the detected apriltag in the camera frame of reference (4x4 matrix).
