3rdTech Virtual Crime Scene at SIGGRAPH 2002

DeltaSphere 3D Scanner Captures Staged Murder for Model Reconstruction

CHAPEL HILL, N.C., July 22, 2002 Visitors to the 3rdTech booth at SIGGRAPH 2002 will be able to walk around in a double murder crime scene. The staged murder scene was accurately captured, with full color, by 3rdTech’s DeltaSphere-3000 3D Laser Scene Digitizer. Walking around the scene is accomplished with 3rdTech’s HiBall-3000 Wide Area Tracker.

  The DeltaSphere-3000 3D Scene Digitizer is a portable, fast and accurate 3D Scanner designed for digitizing ‘room-sized’ spaces and objects. This makes it well suited for crime and accident scene capture and reconstruction. Instead of sending teams of law enforcement officers to make hundreds of manual measurements taking many hours or days, the DeltaSphere-3D Scanner can capture millions of measurements in just 20 minutes. Multiple, detailed scans of a room can be made in an hour or two enabling the measurement of objects and the distance between any two points. In addition, the data can be used to fully reconstruct a model of the crime scene for both investigation and use in the courtroom.

  The murder scene shown at SIGGRAPH will also demonstrate the realistic color captured with the DeltaSphere-3000 Scanner. Amazingly realistic models, in some cases indistinguishable from video of the scene, can be displayed from any viewpoint. The model being shown at SIGGRAPH was developed from the DeltaSphere’s data using the powerful PolyWorks application from InnovMetric Software (www.innovmetric.com).
