AOI projection
==============

An AOI3D scene can be rotated and translated according to a pose estimation before to project it onto camera frame as an AOI2D scene.

![AOI projection](../../img/aoi_projection.png)

``` python
...

# Assuming pose estimation is done (tvec and rmat)

# Project AOI 3D scene according pose estimation and camera intrinsic parameters
aoi2D_scene = aoi3D_scene.project(tvec, rmat, aruco_camera.K)

# Draw AOI 2D scene
aoi2D_scene.draw(frame)
```
