The invention relates to a simulation footprint extracting training method and a simulation footprint extracting training device based on the VR technology. Through simulation footprint extracting combining with the VR technology, different footprint remaining scenes are set in a simulation manner, and then an operator can carry out simulation training according to different simulation scenes. Specifically, the simulation footprint extracting training method sequentially comprises the following steps of setting the VR scene, entering the VR scene, carrying out footprint searchlighting, markingthe scene, carrying out shooting for taking evidence, extracting the footprints, and carrying out operating and judging. The device for implementing the method comprises a computer, a VR device accessing to the computer, and an operation handle connected with the VR device, wherein the computer establishes the footprint extracting virtual scenes of different scenes through a unity 3D platform. During the scene training process, the operator can perform simulation learning on how to use relevant devices and instruments including a camera, an electrostatic adsorption instrument and the like, and footprint extracting is correctly carried out according to the steps, so that more intuitive and more vivid sensory stimulation is provided for the operator, and meanwhile, the high-quality and high-reduction-degree scene environment is also provided.
