Study on Extraction of Desert Vegetation Coverage Based on Segment Anything
Fractional Vegetation Coverage(FVC)is one of the important indicators for grassland monitoring and evaluation.Real-time,rapid,and accurate acquisition of FVC forms the foundation of grassland monitoring and evaluation efforts.In this paper aims to solve the vegetation coverage of desert steppe per unit area,select the SAM model,segment the image per unit area in the way of dot or frame,calculate the total number of pixels of vegetation T and the total number of pixels A,and then calculate the vegetation coverage per unit area by F=T/A,and made the vegetation coverage assessment system.The experimental results show that the Segment Anything Model(SAM)model can make the extraction results of vegetation coverage per unit area more accurate and reliable,and reduce the influence of noise on the coverage extraction.
