Three-dimensional visual perception technology and simulation of individual soldier in combat

In combat simulation, the research on human simulation is a significant part. The human simulation includes perception, decision, behavior. This paper takes an individual soldier as an example and builds a visual perception model of people in the battlefield environment through visual modeling. The model starts with the human visual mechanism, analyzes and simulates the retinal imaging of the human eye, and proposes a conceptual model of individual soldier perception in a battlefield environment. It is determined that perception content, range, and intensity are the three keys to an individual soldier's visual three-dimensional perception. This paper constructs a perception distance model based on the resolution angle, a perception range model based on environmental occlusion, and a perception intensity model based on environmental information. This paper uses Unity3D software to simulate and verify the model. Its perception effect is good, and the research results can provide adequate support for the visual real-time perception simulation of individual soldiers in the virtual battlefield environment.
