  • System and method for vegetation detection from aerial photogrammetric multispectral data
    Patent number: 12718558
    Abstract: Systems and methods for vegetation detection from aerial photogrammetric multispectral data. The method includes: detecting apexes in a height model using Local Maxima (LM) detection; detecting vegetation as detected apexes; performing orthorectification to derive an orthomosaic; generating a fractional map of a vegetation class by applying a Fuzzy classifier on the orthomosaic using the detected vegetation to define the class; generating a binary ridge map using the height model to identify ridges; combining the binary ridge map and the fractional map of the vegetation class to generate a ridge integrated fractional map; performing delineation of individual vegetation on the ridge integrated fractional map on a vegetation class using an active contour algorithm; and outputting the delineated vegetation.
