3D data acquisition
The geometry of the input real object or plant, and possibly other information such as its colours or textures, must be transferred into the computer. This is usually done using passive systems such as cameras (a process called photogrammetry) or active ones such as laser scanners. The result is most often a 3D point cloud or a 3D mesh.
I have not personally designed any acquisition system, but I work with several people doing so. This includes:
The ROMI Plant Imager
The ROMI Plant Imager is a 3D plant phenotyping platform adapted to single-potted plants. It combines a physical scanning station that uses an RGB camera with a powerful image processing pipeline, the Plant Interpreter, to build a 3D representation of plants. Full documentation can be found here.

The GAIA laboratory
The GAIA laboratory is dedicated to research and development in the fields of computer graphics, artificial intelligence and data analysis. Its digitisation hub gathers equipment (cameras, LiDAR, structured light scanners) and expertise for the digitisation of 3D objects, gestures, and physical measurements.
