Agricultural research has experienced a significant advancement with the latest progress in thermal imaging drone technology from Purdue University. The prospect of being able to analyze and apply temperature-based images of fields through the use of drones equipped with thermal sensors has the potential to revolutionize the way agricultural researchers gather and process data, opening up unprecedented opportunities for analysis and application in a wide range of disciplines.
The accomplished team at Purdue’s Plant Sciences has successfully established a groundbreaking protocol for utilizing UAV-based remote sensing thermal imaging. Led by Sungchan “Sun” Oh and guided by Mitch Tuinstra and Yang Yang, the team aims to provide reliable and information-rich data for scientists from various fields in agriculture. This remarkable development is made possible through the cutting-edge UAV technologies provided by GRYFN, a company founded at Purdue.
The incorporation of thermal remote sensing technology has the potential to revolutionize agricultural research by offering a fresh perspective on the various components that drive the success of crops. The use of remote sensors on unmanned aerial vehicles (UAVs) has long been embraced by agricultural researchers. These sensors enable researchers to view crops from the air and examine their structural and functional characteristics. However, the application of thermal sensors has posed a unique challenge due to the difficulty in accurately measuring the surface temperature of a target using conventional sensors such as RGB and LiDAR.
Oh explains, “With thermal imaging, we are able to capture and measure the temperature of a target using different colours which represent varying temperatures. Translating this raw thermal data into a user-friendly format requires meticulously established processes, but the potential for valuable insights is immense.”
The correlation between the temperature of a crop and its overall health and performance is a critical aspect that is being explored by researchers. The thermal data obtained provides valuable information that could be associated with a plant’s growth rate, yield, and even taste. It is also a vital tool for understanding why certain plant varieties thrive under specific conditions while others do not.
Purdue’s Plant Sciences team is committed to creating a user-friendly thermal data product that is easily accessible to agricultural researchers. By flying drones over research plots and processing the raw data into thermal properties in image format, the team is not only paving the way for revolutionary discoveries but also providing actionable data for real-world applications.
The collaboration with GRYFN has further amplified the impact of this development, providing high-end sensors for accurate measurement. The potential to monitor thermal properties of crops during the season with remarkable precision is a game-changer for agricultural researchers. As part of an ongoing effort to create a standard method for processing thermal data, Purdue and GRYFN are actively exploring avenues to make the thermal sensing protocol more user-friendly.
The journey to fully leveraging thermal data for agricultural research is still ongoing, as researchers continue to unlock the enormous potential for this groundbreaking technology. With Purdue’s Plant Sciences team leading the charge, and with the support of innovative companies like GRYFN, the future of agricultural research is looking brighter than ever.
