摘要：

Cases of ship-bridge collision accidents are large problems in many countries. Bridge markings are crucial factors of such problems. However, there is lack of adequate and scientific quantitative analysis and effective setting and evaluation methods in bridge markings setting. The popular methods are still based on experience and afterwards adjustment. Thus, this paper puts forward a resolution to set and evaluate bridge markings based on 3DGIS and VR, for aiding navigation safety and securing bridge self-security. A new framework of bridge markings setting and simulation system based on 3DGIS and VR is proposed. Some key techniques and algorithms including 3D environment simulation, dynamic effects, and simulation, setting and efficiency evaluation of bridge markings are discussed in detail. Based on the above algorithms and strategies, a Bridge Markings Setting and Simulation System based on 3DGIS and VR was developed and applied in Guangdong Marine Safety Administration Bureau.
