Grassland caterpillar larva monitoring and early warning method and system based on unmanned aerial vehicle remote sensing technology

The invention relates to the technical field of grassland caterpillar larva monitoring, in particular to a grassland caterpillar larva monitoring and early warning method and system based on an unmanned aerial vehicle remote sensing technology, and the system comprises a grassland caterpillar larva recognition model, a grassland caterpillar larva prediction model and an early warning coefficient; the grassland caterpillar larva identification model is used for identifying grassland caterpillar larvae; the grassland caterpillar larva recognition model comprises a color optimization attention mechanism; the grassland caterpillars larva prediction model is used for training climate data, geological data and grassland caterpillars larva group data of a to-be-detected area and predicting the accurate number of grassland caterpillars larvae in the current environment; the early warning coefficient is used for calculating the harm degree of the grassland caterpillar larvae through the average density of the grasslan
