COMPARING A SINGLE-SENSOR CAMERA WITH A MULTISENSOR CAMERA FOR MONITORING COFFEE CROP USING UNMANNED AERIAL VEHICLES

There exist two options for digital cameras that can capture the near-infrared (NIR) band. Conventional red–green–blue (RGB, visible bands) with a single sensor provide NIR band visibility based on removal of internal NIR-blocking filter. Alternatively, multisensor have specific each The modified RGB are lower price. In this context, objective study was to compare performance camera obtaining normalized difference vegetation index (NDVI) in an area coffee cultivations. A multispectral five sensors and another only one were used. NDVI field also measured using GreenSeeker handheld manufactured by Trimble. images calibrated radiometrically targets shades gray made napa, calculated after image calibration. calibration curves showed high coefficient determination. value obtained from significant correlation values sensor, making it possible obtain variability pattern index. However, closer sensor.
