摘要 三维激光扫描和无人船测量技术近年来快速发展,沿海吹填区拥有陆地浅水结合的特殊地貌。针对载人测量船难以进入测区,吹填沙地接触式测量效率低、存在危险等情况,本文探讨与研究基于三维激光扫描仪、无人船的水上水下综合测量关键技术。钦州三墩填海区应用该技术,能高效获取地形三维坐标,符合相关规范要求,可以减少生产成本,提高生产效率,但无法实现水下全覆盖扫测。 Three-dimensional laser scanning and unmanned ship measurement technologies have advanced rapidly in recent years.Coastal reclaimed areas have distinctive landforms combined with shallow water.For manned measurement ships,it is difficult to enter the measurement area,and the contact measurement efficiency of dredging sand is low and dangerous.Discuss and review the fundamental technologies of water and underwater comprehensive survey based on 3 D laser scanner and unmanned ship.The application of this technology in Qinzhou Sandun Reclamation Area can efficiently obtain terrain three-dimensional coordinates,comply with applicable specifications,reduce production costs,is improved production efficiency,but it is impossible to achieve subsurface full coverage scanning.
