Infrared Thermography Based Smart Irrigation Scheduling for Horticulture Plants

摘要

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 is an effort towards 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.
