The invention discloses a
forsythia suspensa growth vigor monitoring method based on unmanned aerial vehicle
remote sensing, and particularly relates to the technical field of unmanned aerial vehicle
remote sensing monitoring. S2, calculating a
vegetation index; s3, obstacle recognition; s4, evaluating the growth vigor; and S5, grade drawing. According to the method, a structured
data set is constructed through integration of
multispectral data and space coordinates, a high-resolution
vegetation index map is generated in a pixel-by-pixel calculation mode, non-
vegetation obstacles are accurately recognized by combining
band ratio analysis and threshold judgment,
vegetation index change trends are analyzed through
time series data, and phenological period
standard interval deviation is calculated. Spatial growth trend grade distribution is generated through mapping evaluation coefficients, the
processing logic realizes closed-loop linkage of
data acquisition and analysis, eliminates interference of non-target ground features, improves the accuracy of monitoring results, establishes a dynamic evaluation mechanism, and provides reliable basis for precise
agricultural management.
