Comparison and Real-Life Test of Three Technical Schemes of Holographic Perception of Tunnel Traffic Operation

In view of the problems that the holographic sensing technology scheme of tunnel traffic operation has not yet formed theoretical support, the technical path is not clear, and the landing deployment scheme is not mature, the research and comparative test are carried out around three mainstream holographic sensing schemes: Iidar, millimeter wave radar and high-definition video. Three different holographic sensing schemes are compared and analyzed from several dimensions, such as technical route, deployment scheme, collection results of holographic sensing elements, and detection and analysis of tunnel safety incidents. The research results show that the holographic perception requirements of tunnel traffic operation can be met under the reasonable technical deployment conditions of the three schemes. Lidar has great advantages in detection accuracy, millimeter wave radar has great advantages in anti-jamming, and high-definition video has great advantages in color acquisition.
