The estimation of evapotranspiration with remote sensing began with the support of satellite images, however, technological progress is allowing the incorporation of new imaging platforms, such as images obtained with remotely piloted RPA aircraft, which allow improving the temporal resolution and This is why the present research work was carried out in the experimental irrigation area of UNALM, whose objective was to estimate the evapotranspiration of the rice crop in three varieties¸ V1: IR43, V2: IR71706 and V3: Sahood Ulan 12, applying the model Surface energy balance algorithms for the earth: SEBAL; and the Mapping EvapoTranspiration model at high Resolution with Internalized Calibration METRIC, from the capture of images from multispectral cameras and thermal cameras, mounted on quadcopter-class multirotor RPA, performing a total of 9 flights; A correlation of normalized differential vegetation indices NDVI and IAF leaf area index was performed with two hand sensors: Green Seaker and Ceptometer and a temperature calibration with thermocouples installed in the crop canopy, under saturated soil moisture conditions. constant (E1) and between saturation and field capacity (E2); From which mean ETc values of 2.27 mm d-1 were obtained for E1 and 1.73 for E2 with the SEBAL model and 2.27 mm d-1 for E1 and 1.73 for E2 with the METRIC model, during the tillering phase of the crop; The ANOVA test was performed with p ≤ 0.05, with no significant difference between treatments of the same experiment, but between experiments.
