individual tree segmentation #656

Closed fvcamargo closed 1 year ago

fvcamargo commented 1 year ago

Hello, I am working with UAV based LIDAR DJI L1 point cloud over cherry orchard.

It does not segment the trees individually, may you check the script, please? Also give me insights about? Thanks

las <- readLAS("Malaucene_6oct_lidar.las")

chm1 <- rasterize_canopy(las, res = 0.5, p2r(0.3), pkg = "raster")
ker <- matrix(1,3,3)
chm1 <- raster::focal(chm1, w = ker, fun = mean, na.rm = TRUE)
ttops3 <- find_trees(chm1, lmf(4, 2))
las4 = segment_trees(las, silva2016(chm1, ttops3))

writeLAS(las4, "Oct6Lidar-.las")

I does not work is not a question. Please elaborate. The code looks good
