This makes it an excellent tool for measuring structural dimensions and identifying subtle changes in seawall geometry.
Thermal imaging is another valuable tool in seawall monitoring. Drones equipped with thermal cameras can detect temperature variations that may signal water infiltration, hidden voids, or material inconsistencies - issues that might not yet be visible to the naked eye. This thermal data enhances the quality of digital twin models, giving engineers the ability to proactively monitor seawall conditions.
A single drone inspection can cover several miles of coastline in less than two hours, collecting thousands of high-resolution images, elevation measurements, and thermal data in one go.
Creating Accurate 3D Digital Twin Models
Turning raw drone data into detailed 3D digital twin models starts with precise georeferencing. Ground control points are established using GPS coordinates with survey-grade accuracy, typically within 0.3 feet horizontally and 0.5 feet vertically.
The data is then processed through several key steps to ensure accuracy. Photogrammetry software analyzes the overlapping images to identify shared features and calculate camera positions, producing a sparse point cloud that outlines the basic structure. This is densified by adding millions of data points, creating a highly detailed representation of the seawall surface.
Next, a mesh is generated from the dense point cloud, and textures are applied to create a photorealistic 3D model. Quality control checks are performed to ensure there are no coverage gaps and that the geometry is consistent. The process is fine-tuned to balance detail with file size and processing speed, producing models that meet engineering accuracy standards - often within 2–4 inches for large-scale seawalls.
These final 3D models are designed to integrate seamlessly with digital twin platforms, which support various data formats like point clouds, mesh models, orthomosaic images, and thermal overlays.
