The present work study aimed at evaluating the accuracy of the computerized algorithm included in the TaurusWebs ® software, which allows to calculate the percent of crude protein (% CP) in the dry matter of grasses, from images of grasslands taken by a drone with Red Green Blue – RGB- cameras. The %PC measurements calculated by the algorithm were compared to a reference, Near Infrared Reflectance Spectroscopy (NIRS), from the Corpoica (Agrosavia) Laboratory calibrated for grasses. Forty-two samples were taken for NIRS, 18 of high tropic grasses in Cundinamarca: kikuyo, Pennisetum clandestinum; false poa, Holcus lanatus; Brazilian grass, Phalaris arundinacea and 24 from the low tropics in Tolima, Colombia: pangola, Digitaria decumbens; pará, Brachiaria mutica; Bermuda, Cynodon dactylon and coloswana, Bothriochloa pertusa. The results of the NIRS were compared against the evaluations ...

The aim of this study to the evaluate the precision of the Red, Green, Blue (RGB) image analysis algorithm included in the TaurusWebs V2017® software for calculating the percentage of neutral detergent fiber (NDF) in the dry matter of grasses, from images of the grasslands taken by a drone with RGB camera. The results were compared with NDF values calculated with near infrared spectroscopy (NIRS). Forty-two samples were taken for NIRS: 18 from grasses from the high tropics in Cundinamarca: kikuyu (Pennisetum clandestinum), velvet grass (Holcus lanatus) and reed canarian grass (Phalaris arundinacea) and 24 from the lower tropics in Tolima, Colombia: pangola (Digitaria decumbens), para (Brachiaria mutica), Bermuda grass (Cynodon dactylon) and silver grass (Bothriochloa pertusa). The results were compared against 180 evaluations made with the algorithm of the images of the same grasses whe...
