Abstract
Infrared thermography has gained significant acceptance in agriculture practices for different applications ranging from crop yield estimation, fruit maturity evaluation, plants disease detection, nursery monitoring, bruise detection, irrigation scheduling, etc. The present study proposes using thermal imaging route for developing an efficient irrigation scheduling system for the horticulture plants. The conventional method of using the soil moisture sensors have many limitations, namely it indicates the water content of the soil but doesn’t indicate the actual water needs of the plant. Moreover, correct positioning of the contact sensors on the agriculture filed is also challenging task. Our proposed method aims at establishing a quantitative relationship between the thermal signature and the water stress developed in horticulture plants, through infrared thermography monitoring. The temperature measured is standardized by subtracting the ambient air temperature from mean canopy temperature. The change in the thermal signature of the leaves is a good indicator of the water needs of the plant. This observation helps us in developing a smart irrigation system.
