Using Metashape For Thermal Image Photogrammetry

Thermal infrared (TIR) imaging is a powerful technology for understanding ecosystem processes and sustainable agricultural systems. TIR sensors are becoming increasingly common on drones, and the applications of TIR images are increasing. Single TIR photos or TIR videos can be invaluable for infrastructure inspections or in search-and-rescue operations. In agriculture and natural resources, the power of TIR data comes when multiple photos can be combined into orthomosaics of large fields or landscapes. However, TIR imagery has some unique traits that can make it challenging to work with it in photogrammetry applications. In this lab, we will work through import, alignment, and creation of TIR orthomosaics. For a great introduction to drone/UAS thermal imaging, check out this (open-access!) paper by Messina and Modica (2020) - https://doi.org/10.3390/rs12091491.
