Imagery

Panoramas

Image files

  • Image type : Ladybug 5 or Ladybug3, equirectangular panoramas
  • Image resolution : ratio 2×1, 8000×4000 advised for Ladybug 5, 5400×2700 for Ladybug 3
  • Files : *.jpg files, each image is one jpg file
  • File name : exactly as “Filename” value of photo position file, see below
  • Folder structure : all files in one folder

Image positions and orientations file

  • Files : one asccii *.txt file
  • Rows : each image is one record
  • Columns : tab separated (char9), headers, with exact order as the example below
  • Value “Filename” : file name as on disk, with file extension
  • Value “Latitude”, “Longitude” : any supported projected coordinate system can be used, but all mobile mapping resources should have the same crs
