A-Z INTRODUCTION TO MODERN PHOTOGRAMMETRY

AZ-introduction

The basic theory that governs modern photogrammetry is presented. Indicative topics include: What is photogrammetry and how does it compare to competing techniques, basic principles of photography, taking photographs for extracting measurement data, aerotriangulation, internal and external accuracy, photostationary points, best practices, etc.

  • Lenses and Cameras: What is the best combination?
  • Shutter Type: Mechanical vs. electronic/rolling shutter
  • Spatial Analysis: Relationship between geometric accuracy and spatial resolution
  • Photostationary Points: Absolute and relative accuracy

No Prior Knowledge Required

This training is open to everyone, with no prerequisite knowledge or experience required.
