基于Unity3D的自航耙吸船三维疏浚辅助监控系统
A 3D Dredging Auxiliary Monitoring System for Self-Propelled Trailing Suction Hopper Dredger Based on Unity3D

中国疏浚业的现代化历程已逾百年，自新中国成立以来，该行业经历了从缓慢到迅速的发展阶段。尽管疏浚船的高效作业得益于先进的可视化系统，但现有系统在效率和精度方面仍有待提升。为解决这一问题，本文研发了一套基于Unity3D的自航耙吸船三维疏浚辅助监控系统，并成功应用于实体疏浚船。该系统采用数字孪生技术，通过骨骼系统构建了1:1精细化的“船舶–设备–部件”数字孪生体，实现了对施工作业船的精确模拟。通过整合传感器数据并将其转化为三维模型的动作驱动数据，这些数据与船舶数字孪生体紧密结合，实现了数字孪生体与实际船舶动作状态的无缝同步。这一创新系统的开发，不仅提高了疏浚作业的质量和效率，而且为疏浚行业的智能化和自动化转型提供了强有力的技术支持，预示着该行业可持续发展的未来。
The modernization journey of China’s dredging industry has spanned over a century. Since the founding of the People’s Republic of China, the industry has gone through stages of development from slow to rapid. Although the efficient operation of dredging vessels benefits from advanced visualization systems, there is still room for improvement in terms of efficiency and accuracy in existing systems. To address this issue, this paper has developed a 3D dredging auxiliary monitoring system for self-propelled trailing suction hopper dredgers based on Unity3D, which has been successfully applied to a physical dredging vessel. The system utilizes digital twin technology to construct a 1:1 refined “ship - equipment - component” digital twin body through a skeletal system, achieving precise simulation of the construction vessel. By integrating sensor data and converting it into motion-driven data for the 3D model, these data are closely integrated with the digital twin of the vessel, achieving seamless synchronization between the digital twin’s motion state and the actual vessel. The development of this innovative system not only improves the quality and efficiency of dredging operations but also provides strong technical support for the intelligent and automated transformation of the dredging industry, heralding a sustainable future for the industry.
