Agisoft

This page describes the original Agisoft aerial mapping resources for Orbit import.

Use the corresponding Orbit Import Template to import the described original data.
It is recommend to read first Orbit Mapping Resource.

Planar Images

Image files

  • Image type: Undistorted (corrected distortion and Central Principal Point) planar images.
  • File format: Each image is one *.jpg file.
  • Filename: Exactly as in image positions file, see below.
  • Folder structure: All files in one folder.

Image Positions File

  • File format: One ASCII file.
  • File structure Rows: The first line is the header, each image is one record.
  • File structure Columns: space-separated (char9), with exact order as the example below (more columns are allowed but first 7 should be as shown below).
  • Value of Filename: Filename as on disk, with file extension.
  • Value of Coordinates: any supported coordinate system can be used, Long/Lat order for geographical coordinates, decimal notation, without thousands separator.
  • Value of Angles “Omega;Phi;Kappa” : Omega, Phi, Kappa orientation angles, degrees.

In Agisoft post-processing software v1.4 export of Image Positions is called 'Export Cameras'. For more information please refer to Agisoft Manual

Camera calibration file

The camera calibration information can be found in the “Report” exported from Agisoft

  • File format: One *.pdf file, containing among others camera calibration information (camera name, sensor width in pixels, sensor height in pixels, sensor pixel size in micron, F pixels, Cx pixels, Cy pixels) and CRS.

The camera calibration parameters must be entered before Create Run, the 1st step of the Import Run procedure.
To facilitate import, your specific camera calibration values can be registered inside the Orbit template to avoid entering these values at import each time. Contact Orbit Support if assistance is needed.

Point Cloud

  • File format : One or more *.las files.
  • File structure : Las version 1.2.

Orthomosaic

The ortho is not a part of the UAS Mapping Run, it can be added separately to the Map view.
Convert the Orthomosaic file into *.omi format for enhanced performance.
