In today’s rapidly evolving world, the use of photogrammetry software has become a cornerstone of aerial mapping and drone surveys. This article explores on uses of photogrammetry software, shedding light on its functionalities, pricing considerations, and specialised applications in the spheres of aerial mapping and drone surveys.

Understanding Drone Photogrammetry Software

Understanding photogrammetry software

Photogrammetry software serves as a powerful catalyst in the conversion of two-dimensional photographs into precise 3D models and maps. Let’s delve deeper into its essential aspects:

  • Image Processing: This software initiates the process by analyzing a series of overlapping images taken from various angles. It intelligently identifies common points within these images, establishing reliable reference points.
  • 3D Reconstruction: Using these reference points, the software goes on to craft intricate 3D models or maps of the surveyed area. It accommodates both close-range and aerial photogrammetry, rendering it versatile for a myriad of applications.
  • Orthomosaics: A remarkable feat of this software is its ability to seamlessly stitch images together, giving birth to orthomosaics. These are geometrically corrected aerial images, ensuring a uniform scale throughout the entire image.

How does Drone Photogrammetry software works?

Photogrammetry software works via analyzing the spatial relationships and perspectives within multiple images to reconstruct the shape and dimensions of the photographed subject. Here’s a simplified explanation of how photogrammetry software works:

1. Image Acquisition:

Multiple photographs of the same object or scene are captured from different viewpoints. These images should ideally have a significant overlap to ensure accurate reconstruction.

2. Feature Extraction:

The software identifies and extracts distinctive features or points within each image. These features could be corners, edges, or other unique patterns that can be easily matched across multiple photos.

3. Matching Features:

Corresponding features in different images are matched by analyzing their positions, orientations, and descriptors. This process establishes correspondences between points in different photographs.

4. Solving Geometry:

Using the matched features, the software calculates the camera positions and orientations for each image in 3D space. This step involves solving the geometry of the scene based on the known camera parameters and the identified feature correspondences.

5. Point Cloud Generation:

The software generates a point cloud, which is a set of 3D coordinates representing the locations of the matched features in the real-world space. This point cloud is essentially a sparse representation of the object’s surface.

6. Surface Reconstruction:

The sparse point cloud is used to create a denser and more detailed point cloud, often referred to as a dense point cloud or a 3D point cloud. Additional algorithms may be employed to interpolate and fill in gaps between points.

7. Mesh Generation:

The point cloud is then used to create a surface mesh, connecting the points to form a continuous 3D representation of the object’s surface. The mesh consists of vertices, edges, and faces that define the object’s geometry.

8. Texture Mapping (optional):

If the original images contain color information, the software can map the textures from the images onto the generated 3D model, providing realistic visual details.

9. Refinement (optional):

Some photogrammetry software may offer tools for refining the generated model, such as smoothing surfaces, removing outliers, or adjusting parameters to enhance the accuracy and visual quality.

The final output is a 3D model that closely represents the shape and structure of the photographed object or scene. Photogrammetry is widely used in fields such as archaeology, geology, forestry, urban planning, and computer graphics for applications like virtual reality and video game development.

The financial aspect of photogrammetry software can be a pivotal factor in your decision-making process. Price points can vary widely depending on several factors, including features, capabilities, and licensing options. Here’s a breakdown:

  • Open-Source Software: Open-source photogrammetry tools like MicMac and VisualSFM stand as accessible options, as they are freely available. These are ideal for smaller projects or individuals working with limited budgets but there can be certain issues with the free version.
  • Commercial Software: Aerologixmaps Commercial photogrammetry software often offer more advanced features and comprehensive support. Prices can range from a few hundred to several thousand dollars, depending upon the edition and licensing terms.
  • Subscription Models: Some software providers extend subscription-based pricing models. This allows users to access the software for monthly or annual fees, catering to the flexibility required for short-term projects.

Aerial mapping stands as one of the foundational applications of photogrammetry. It enables surveyors, cartographers, and environmental scientists to craft intricate maps and topographic models of expansive areas. Photogrammetry software tailored for aerial mapping often incorporates specialised features such as:

  • Georeferencing: Guaranteeing that the produced maps accurately align with real-world coordinates.
  • Digital Elevation Models (DEMs): Facilitating the extraction of elevation data from imagery, which is then employed to generate detailed 3D terrain models.
  • Automatic Tie Point Detection: Streamlining the alignment process by autonomously identifying common points within images, significantly expediting the mapping process.
