Automatic counting carried out by machine learning and subsequently, NDVI classification of each plant thanks to the multispectral orthophoto.
(Orthophoto carried out with the aerial images of the Agrowing A7R4 sensor and the Agisoft Metashape software for the post-processing part).
Above, the multispectral orthophoto (NIR-G-R) built with Agisoft Metashape software.
Thanks to the quality and high resolution of the images recorded by the Agrowing multispectral sensor, the orthophoto built at sub-centimeter resolution make it possible to precisely count the number of plants (3675 lettuces in totality from the extract above) and to then classify them according to their relative plant vigor (based on the calculation of the NDVI index).
Thus, it becomes possible to isolate each plant according to their vigor (low or high) and to easily identify, for example, plot areas with low or high yield.
