CLAIMS:

1 . A plant cultivation system, which includes

plant sensors in the form of image sensors, arranged to capture digital plant images;

processing hardware including a processor, a data storage facility in communication with the processor and input/output interfaces connectable to the plant sensors and in communication with the processor, the hardware being configured to implement a convolutional neural network (CNN) trained from a library of plant images to recognize predefined plant conditions from the digital plant images captured by the image sensors and to provide a matching score of a plant image when compared to the predefined plant conditions with which the CNN has been trained; and

a reference library containing treatment regimes associated with predefined plant conditions, the output interface of the processing hardware arranged to present the predefined plant condition and associated treatment regime to a user.

2. The plant cultivation system of claim 1 , in which the image sensors are selected from any one or more of visible spectrum sensors, multispectral sensors, hyperspectral sensors, thermographic sensors and Chlorophyll fluorescence sensors.

3. The plant cultivation system of claim 1 , in which the plant sensors additionally include environmental sensors selected from humidity sensors, temperature sensors, pH sensors and CO2 sensors.

4. The plant cultivation system of claim 1 , in which the reference library includes a plant disease database, an insect and pest database and a weather database.

5. The plant cultivation system of claim 1 , in which the CNN is trained with data from the reference library to predict plant growth and yield.

6. The plant cultivation system of claim 1 , in which the plant cultivation system includes a control system and environmental control arrangement, the control system controllably connected to the environmental control arrangement, in use to control a plant cultivation environment.

7. The plant cultivation system of claim 6, in which the environmental control arrangement includes dosing pumps, water pumps, humidity controllers and temperature controllers.

8. The plant cultivation system of claim 7, in which the plant cultivation system is arranged into zones with associated plant sensors and an environmental control arrangement per zone.

9. The plant cultivation system of claim 8, in which each zone is defined in terms of global positioning system (GPS) coordinates.

10. A method of cultivating plants, which includes

receiving plant information from plant sensors, the plant information including digital plant images;

processing the digital plant images with processing hardware, which includes a CNN trained from a library of plant images to recognize predefined plant conditions from the digital plant images and to provide a matching score of a plant image compared to the predefined plant conditions with which the CNN has been trained;

accessing a reference library containing treatment regimes associated with predefined plant conditions; and

presenting predefined plant conditions and associated treatment regimes based on the digital plant images to a user.

1 1. The method of cultivating plants of claim 10, which includes the earlier step of pre-processing digital plant images by means of any one of exposure adjustment, contrast adjustment, gamma correction, rotation, normalization, Sobel filtering and image scaling.

12. The method of cultivating plants of claim 10, in which the step of processing the digital plant images includes learning techniques such as logistic regression, linear discriminant analysis, K-nearest neighbours, decision trees, random forests, Gaussian Naive Bayes techniques and support vector machine techniques.

13. The method of cultivating plants of claim 12, in which the step of processing the digital plant images further includes learning techniques selected from any one or more of image moments, Haralick textures and colour histograms.

14. The method of cultivating plants of claim 10, in which the matching score is in the form of an overall health score, which takes into account all the relevant environmental- and plant factors.

15. The method of cultivating plants of claim 10, in which the step of presenting predefined plant conditions and associated treatment regimes based on the plant images includes providing a visual alert schedule.

16. The method of cultivating plants of claim 15, in which the step of providing a visual alert schedule includes providing alerts in terms of humidity, light, pH, temperature, mineral imbalance, CO2 levels, insects on plants and plant disease detected.

17. A plant cultivation system as claimed in claim 1 , substantially as herein described and illustrated.
