A major task of forensic investigations is the documentation and interpretation of evidence to reconstruct a forensically relevant incident. To accomplish this task, a scene is documented not only with photographs but also with 3D documentation technologies. The resulting 3D data are used for 3D visualization and to perform 3D reconstructions. In this article, we present an approach for using forensic 3D data in conjunction with virtual reality to perform scene walkthroughs in the context of witness or suspect interrogations. The aim is to provide a method for scene visits showing the original scene even years after the incident. These scene walkthroughs in VR can be reproduced and allow to see through the eyes of a witness by recording their behavior and actions. These recordings allow subsequent examinations and reconstruction to support the investigation and scene understanding and can be used as evidence in court.
法医调查的一项主要任务是记录和解释证据，以重建与法医相关的事件。为完成这项任务，不仅要用照片记录现场，还要使用三维记录技术。所得到的三维数据用于三维可视化和进行三维重建。在本文中，我们提出了一种将法医三维数据与虚拟现实相结合的方法，以便在询问证人或嫌疑人的背景下进行现场漫游。目的是提供一种即使在事件发生数年之后仍能展示原始场景的现场参观方法。这些虚拟现实中的现场漫游可以重现，并通过记录证人的行为和动作，让人们以证人的视角去看。这些记录便于后续的检查和重建，以支持调查和对现场的理解，并且可在法庭上用作证据。
