Research on VR Acquisition Technology of Expressway

With the full saturation of the highway infrastructure, asset management, operation and maintenance, fine service will face a comprehensive upgrade and development. This paper described the principle, technical process and operation method of the virtual reality technology in the application of highway asset management. It provided a new rapid acquisition technology for the asset management of expressway. After the verification of this topic, a number of acquisition technologies such as UAV, laser scanning and 360° panorama can quickly obtain highway asset information, achieve rapid updates of highway assets, meet the needs of meticulous management, highway applications in the promotion of a broad application prospects.
