- Photogrammetry Tool for Precision Agriculture

Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring, and interpreting photographic images and patterns of electromagnetic radiation images and other phenomena.

Traditionally, farming is practiced by performing tasks such as planting or harvesting on a predetermined schedule. However, collecting real-time data can help farmers make the best decisions about planting, fertilizing and harvesting crops. This method is called precision agriculture. In this context, there is growing interest in technological tools adapted to crop management strategies. Therefore, this study aims to analyze and compare photogrammetry-based image processing tools in the agricultural field. 

Additionally, a land case study involved using a drone to take multiple photos and analyzing them using photogrammetry software to obtain an orthophoto. This software can help with relevant biomass analysis, drought stress, irrigation scheduling, forecasting agricultural production, monitoring nutrients, pests and diseases affecting photographed crops.
