Crime scene reconstruction plays a crucial role in forensic applications. Recent advancements in technology and the accessibility of 3D imaging techniques has become useful in crime scene investigation. The need for precise mapping and measurements had led to the adoption of laser scanning and 3D modeling softwares. Digital 3D modeling, the process of creating a digital 3D representation of an object or surface, uses the data from laser scanning to recreate a specific space. The creation of digital 3D models of crime scenes help determine the events leading up to a crime. Unlike 2D traditional methods of photographs and sketching, 3D models allow investigators to explore the scene in a 3D world. With the use of virtual reality, users are able to step into the reconstructed space to view the scene from multiple perspectives. Using contactless laser scanners, entire crime scenes are able to be fully documented with minimal physical interaction with the crime scene. Thousands of data points are collected which are put into 3D modeling softwares. This allows for analyses of bloodstain patterns, bullet trajectories, weapons and objects, and human bodies all in a 3D space. Since it is a newer technology, there are several considerations when it comes to accuracy when implementing these technologies in a court setting, however accuracy increases with skilled professionals and research.
