Integrated 3D Farm Modeling with Photogrammetry and Optical Camera Communication

Sensor data acquisition has many benefits in agriculture, and research is actively being conducted into the communication of sensor data. 3D modeling of farmland using photogrammetry has also been reported in several studies. However, there has never been a system that can integrate sensor data acquisition and 3D model generation to create a farmland digital twin. This paper proposes an integrative creation of a farmland digital twin with photogrammetry and Optical Camera Communication (OCC) using a camera. Utilization of OCC as a means of communication allows for high-density sensing at a low cost. This system facilitates decision-making by easily comparing farmland situations in detail. We conducted a preliminary experiment at a haskap farm in Chitose City, Hokkaido to demonstrate the feasibility of the proposed system.
