Flight Altitude Of Uas And Overlap Of Images By Multispectral Camera Optimization For Crop Scouting

Abstract

When preparing a crop scouting mission using UAS, two parameters are set: flight altitude and overlap of images. In practice, crop scouting is most often done at altitudes of 70 to 100 meters, and the switchover is most often between 50 and 100%. The research question that is dealt with in this paper is whether there is a significant difference in the obtained light reflection indexes and consequently postprocessed vegetation indexes, depending on height and overlap. The flight height of the UAS dictates spatial resolution, and the switching dictates the time resolution of the reconnaissance. The research was carried out on the experimental plot of barley. The missions were consecutive and performed in perfect weather conditions. The sky was clear, and the light was approximately uniform during all missions with variable heights and overlaps.
