Change Detection Model

A Change Detection Model is a digital representation that identifies and visualises physical differences between two or more 3D datasets captured at different points in time. It is commonly used in construction, infrastructure maintenance, asset monitoring, and environmental studies to track modifications, degradation, or progress.

The model typically compares point clouds, mesh models, or other spatial datasets to detect positional changes, deformations, or object additions/removals. It can automatically generate deviation maps, colour-coded visualisations, or alerts based on predefined thresholds.

Change Detection Models play a key role in quality assurance, construction progress tracking, and condition assessments. In industrial environments, they help ensure that physical changes align with design plans, enabling proactive maintenance and reducing the risk of costly errors.
