Automatically recognizing Boytritis in tomato plants
For the EUREGIO-Project ‚Healthy greenhouse‘ (Gezonde kas) we developed a system that measures the photosynthesis activity of tomato plants. Measuring the photosythesis gives an indication of the plant’s stress level, which causes a higher risk of boytritis (mould).
- A 3D camera detects the stem of the tomato plant and determines the position of the system.
- When the system is in front of the tomato plant it illuminates the plant with red light. After that a Chlorophyll fluorescence camera measures the light that the plant emits back (Chlorophyll fluorescence).
- If the plant shows indications of higher photosynthesis, the system spray it with fungicide, so the boytritis doesn’t spread.
