Virtual Reconstruction of a Nest Proves a Crime
When a protected bird's nest is damaged, proving it was active is crucial to prosecute the crime. Experts now turn to 3D digital technology to transform physical remains into irrefutable legal evidence. 🕵️♂️
Capturing Evidence with Millimeter Precision
The first step is to digitalize each fragment found at the scene. A high-precision 3D scanner, such as the Artec Space Spider, is used to record the geometry and texture of the remains, no matter how small. These precise 3D models become the digital material foundation of the investigation.
Forensic Documentation Process:- Fragment Scanning: All recovered remains are digitized to preserve their exact state.
- 3D Model Generation: Each piece is converted into a digital asset with geometric and color information.
- Photogrammetric Reference Creation: Photographs are processed with software like Agisoft Metashape to obtain a verification model.
The technique transforms seemingly unrelated remains into solid evidence that speaks for itself in court.
Assembling the Puzzle in Virtual Space
With the models on the computer, an expert manipulates them in digital sculpting software like ZBrush. Guided by the typical structure of the species, consulted in databases, they join the digital pieces like a complex three-dimensional puzzle. This virtual assembly reconstructs the original architecture of the nest.
Digital Reconstruction Methodology:- Manipulation in ZBrush: Digital pieces are positioned and adjusted to fit precisely.
- Consultation of Ornithological References: Specialized knowledge is used to guide the reconstruction of shape and materials.
- Cross-Verification: The photogrammetric model is used to compare and validate the digital assembly.
Presenting Visual Evidence in Court
The resulting complete 3D model is compelling visual evidence. It allows for clear visualization of the interior chamber and materials, evidencing that the nest was in use. This digital asset is presented in court as objective evidence, helping the judge or jury to understand the magnitude of the damage caused to a protected species. Thus, loose twigs tell their story before the law. ⚖️
