Simulation research of crime scene based on UDK

The sence simulation is an important part of virtual reality system, it provides powerful methods support to the research of forensic science. First, we research the mainstream virtual engine and choose the UDK (Unreal Development Kit) for simulation, which is fully functional and easy to be used. Then, the prototype system of three-dimensional reconstruction for crime scene was established. The flow of virtual reality simulation, scene management, model and texture were discussed. Finally, this paper takes murder case as an example and finds a solution for the problem of scene investigation and reconstruction, which can promote the development of criminal technology, observe the crime scene from Multi-angle and improve the efficiency and the accuracy of judgment.
