Burglaries in vacation apartments, whether by deception or unauthorized access, present a particularly complex crime scene. After the incident, the urgency to resume tourist activity alters or erases crucial evidence. Photogrammetry and 3D laser scanning emerge as vital tools to comprehensively document the post-event state, immortalizing the altered scene with millimeter precision before any intervention, thus preserving its probative integrity.
Intruder Capture and Vector Analysis Methodology
The documentation begins with a laser scan that generates a geo-referenced point cloud of the entire space, including windows, locks, and possible forced entry points. Complemented with high-resolution photogrammetry, a photorealistic textured model is obtained. This digital twin allows for vector analysis: reconstructing the most probable trajectory of the perpetrator from the entry point to the stolen objects, measuring exact distances, and simulating lines of sight to determine what could or could not be seen from a specific position, contrasting with contradictory statements.
Probative Value and State Comparison in Trial
The greatest forensic value arises from contrasting the 3D model of the altered scene with the virtual reconstruction of the original state, based on inventories and pre-burglary photos. This objective comparison, presentable in any browser or virtual reality system, allows the jury to navigate both versions, intuitively visualizing discrepancies and the mechanics of the crime. The 3D scene thus becomes a clear, irrefutable narrative proof that transcends cold verbal descriptions or isolated photographs.
