Prepare Oblique Data Ultracam Osprey

This page describes how to prepare Ultracam Osprey oblique resources for Orbit.
Using the Vexcel Ultracam Orbit import templates prepared resources can be imported into Orbit.

Today the Ultracam Osprey Camera 1 should not be imported, skip the import step and continue from Camera 2.

Imagery

Image files

  • Files : *.tif files, each oblique image is one tif image file.
  • Naming : Exactly as the result of “Concat([Nr],[Filename_Suffix])”, from the photoposition file bellow.

Image positions and orientations files

  • File : one *.csv or *.txt file for each camera
  • Structure : Flat ascii text file
    • Rows : each image is one record
    • Columns : semicolumn separated (char59), headers, with exact order as the example below.
  • Structure of file name : Exactly as the result of “Concat([Nr],[Filename_Suffix])” from the example bellow.
  • Crs : Any supported projected coordinate system can be used, but all imported oblique resources should have the same crs.
Camera,Nr,X,Y,Z,Rot_X,Rot_Y,Rot_Z
       2;        2336;    1973552.6577;     565548.9593;       1029.4173;   -45.21102;     0.45022;   -90.64410;

Camera calibration

Pixel_Size_mm = 0.00600
Principal_Distance = 123.009695
PPA_X = 6.842097
PPA_Y = 0.014417
Image_Width_mm = 53.40000
Image_Height_mm = 39.90000

DEM

Raster file

  • File : one *.tif file with corresponding *.tfw
  • Naming : free of choice
  • Crs : Any supported projected coordinate system can be used, but all imported oblique resources should have the same crs.
