Overview of the development of video see through technology in mixed reality technology and simulation application

With the wide application of mixed reality (MR) technology in many important fields, MR technology is also becoming increasingly popular in the field of military simulation. By analyzing the differences between video see through and optical see through from principle to application, the advantages of video see through in the field of simulation are listed. By comparing the current situation of MR technology's simulation application, the development status of helmet display, tracking registration, virtual-real occlusion, and human-computer interaction at home and abroad are analyzed in detail. The technical difficulties and future application prospects of video see through are proposed, which provide reference for the research of video see through in the field of virtual reality.
