Introduction

• Photogrammetry
• Photogrammetry is the technique of measuring
  objects (2D or 3D) from photogrammes. Its most
  important feature is the fact that the objects
  are measured without being touched.
• Photogrammetry can be divided into
•   Far range photogrammetry
• - Aerial photogrammetry, etc
• Close range photogrammetry
• - Terrestrial Photogrammetry, etc

Basic Knowledge

• Triangulation
• If several objects have previously established
  coordinates, the distance and angle of unknown
  targets can be calculated.
• Metrology
• 3D coordinates can be reproduced from 2D
  photographs.
• Bundle Adjustment
• The most probable coordinates for each object,
  the error estimates, and estimates of precision
  for the entire process are determined through
  this process.

Photogrammetry in Civil Engineering Case 2

• The non-contact measurement is employed because
  of the physical limitations in manual
  measurements.
• Results The widths of cracks change from place
  to place.
• A non-contact measure method improves the
  traditional time-consuming measurement.

CONCLUDING REMARKS

• The photogrammetry technique is a powerful and
  productive tool for accurate and robust
  measurement.
• The technique has been used in Civil Engineering
  due to the following advantages.
• - Time and efforts can be reduced at any
  measurement or surveying work.
• - The measurement can be repeated many times in
  short period.
• The data can be transmitted through network
  immediately.
• Highly concentrated data can be obtained.
• The real-time tracking of measurement is
  possible.
