The Balat Project

1
The Balat Project

• Architectural Photogrammetric Application

2
The Aim Of The Project

• Obtain 3D Information for the Architectural
  Restoration.
• Obtain 3D Cad model for animation or
  visualisation for the real issue of this
  historical site.

The Procedure of The Work

• Data Acquisition
• Geodetic Network
• Measuring The Control Points
• Taking Images From The Facades With The
  Photogrammetric Cameras

• Photogrammetric Restitution
• Digital Photogrammetric Methods
• Analytic Stereo Restitution

Data Acquisition

• Geodetic Network Design
• Polygonation for the Facades.
• Geodetic measurements for Control Points signaled
  on the Facades.
• The instrument of this work was Pentax ATS-102
  with 2 miligon angular precision.
• The network adjustment had been made with 2.5 cm
  accuracy for each direction of all control points
  on the facades.
• Photogrammetric data capture had been done with
  three cameras
• Rollei(with 50mm and fish eye focuses), UMK
  (with 100mm focus length), P31(with 45mm focus
  length) of which the inner orientation parameters
  were well known.

Photogrammetric Restitution

• Digital and Analytical Photogrammetric
  Application
• Digital Restitution was done with photogrammetric
  software Pictran D-B.
• Bundle Block Adjustment was done with Pictran B
  with less than 0.5cm accuracy in the object
  scale.
• The model had been measured with Pictran D on the
  same projection plane which determinated also
  less than 0.5 cm accuracy.
• The Analytic Stereo Plotter KERN DSR-11 was used
  for determining the 3D properties of the
  important details of the facades, for example
  the distance of the balcony from the main facade
  and the depth of the frame of the windows.
