How many photos do you need for photogrammetry?

Photogrammetry Training Expert on UrbanPro.com

Introduction

As an experienced tutor registered on UrbanPro.com specializing in Photogrammetry training, I understand the importance of capturing the right number of photos for successful photogrammetric processes.

Importance of Adequate Photo Coverage

Photogrammetry relies on the accurate reconstruction of a 3D model from 2D images. To achieve optimal results, it's crucial to capture a sufficient number of well-distributed photos.

Factors Influencing Photo Quantity

1. Object Complexity: The complexity of the object being modeled plays a significant role. Intricate or detailed subjects may require more photos for accurate representation.

2. Resolution of Camera: Higher resolution cameras capture more details, reducing the need for an excessive number of photos. However, a balance must be maintained.

3. Overlap and Coverage: Adequate overlap between photos ensures better reconstruction. Typically, a 60-80% overlap is recommended for terrestrial photogrammetry.

Recommended Number of Photos

1. Small to Medium Objects:

   • For simpler objects, a minimum of 30-50 photos is recommended.
   • Maintain a consistent angle and distance for each shot to ensure comprehensive coverage.

2. Large and Complex Objects:

   • Larger or more complex subjects may require 100 or more photos.
   • Ensure varied perspectives and angles to capture all details.

Online Coaching and Practical Guidelines

When providing online coaching for Photogrammetry, I emphasize the following practical guidelines:

1. Hands-On Practice:

   • Encourage students to apply theoretical knowledge through hands-on exercises.
   • Provide assignments with varying object complexities to develop a real-world understanding.

2. Simulation Tools:

   • Introduce students to photogrammetry simulation tools to practice capturing the right number of photos in a controlled environment.
