Frame synchronization detection technology is the key of virtual reality frame synchronization, which directly determines the immersion and interaction effect of mine emergency rescue virtual simulation scene. However, the existing frame synchronization detection technology cannot meet the special needs of multi-channel and high real-time of mine rescue virtual reality. In order to solve this problem, this paper puts forward the realization way of frame synchronization technology suitable for mine emergency rescue virtual simulation. The implementation approach takes the composite design of blind frame synchronization detection and high-speed parallel frame synchronization detection technology as the core, and cooperates with high-performance LDPC channel coding and high-speed parallel module to realize the detection of high-speed data flow, which provides an idea for realizing the frame synchronization of mine emergency rescue virtual simulation. By using these technologies, the real-time and synchronization of images, sounds and actions in different scenes of mine emergency rescue virtual simulation are greatly improved, and the immersion of virtual-real interaction and multi-person collaboration is improved.
