Image files

  • Image type : Preferably undistorted (corrected distortion and Central Principal Point) planar images.
  • File format : Each image is one *.jpg file.
  • File name : Corresponds to the name in the image positions file, see below.

Image Positions File and Camera Calibration

*.xml Bentley export X-right Y-down Yaw, Pitch, Roll angles
Camera calibration information is included in the Bentley export.

  • Value of Coordinates “X;Y;Z” : Any supported coordinate system, decimal notation, without thousands separator.
  • Value of Angles “Yaw, Pitch, Roll” : Supported Mapping Resources, degrees.
  • File format : One *.xml file (UAS module allows import of one camera only so there should be only one Photogroup in the file)
