OpenDroneMap Outputs

Ang mga nakalista sa ibaba ay ang mga makatutulong na outputs sa ODM procedure.

Point Cloud

odm_georeferencing/odm_georeferenced_model.ply/laz/csv` -- Ang georeferenced point cloud sa iba't-ibang file format

3D Textured Model

odm_texturing/odm_textured_model.obj -- The textured surface mesh odm_texturing/odm_textured_model_geo.obj -- The georeferenced and textured surface mesh

Maaaccess ang point cloud at textured meshes gamit ang Meshlab. Buksan ang Meshlab at piliin ang File:Import Mesh at piliin ang textured mesh mula sa lokasyon tulad ng mga sumusunod: odm_texturing\odm_textured_model.obj

Orthophoto

odm_orthophoto/odm_orthphoto.png -- The orthophoto, pero eto ay simpleng png na walang georeferencing information.

odm_orthophoto/odm_orthphoto.tif -- GeoTIFF Orthophoto. Maaaring gamitin ito sa QGIS bilang raster layer.

DTM/DSM

Ang DTM/DSM ay magagawa lamang kapag ang --dtm o --dsm na opsiyon ang ginamit. Tignan ang tutorial on elevation models para sa mas maraming opsiyon ng paggawa.

Ang data ay maitatago sa:

  • odm_dem/dtm.tif

  • odm_dem/dsm.tif
