摘　　要：提出了一种基于激光点云与建筑信息模型(BIM)技术的复杂舱舱容计算方法。以复杂液货舱三维点云数据为基础,对复杂舱舱壁与内部构件进行了分割;利用BIM技术对舱壁点云数据及船舱构件点云数据进行了三维重建;利用船舱三维模型进行了船舱不同姿态下的实时舱容计算。选用上海某船舱点云数据进行了方法验证,研究结果表明,该方法能够快速、精确地获得船舱不同姿态下的舱容数据,可靠性强,具有很高的实用价值。A calculation method of complex tank capacity is proposed based on the laser point cloud and building information modeling (BIM) technology. The bulkheads and inner components are first segmented based on the three-dimensional (3D) point cloud data of complex tank. The 3D reconstruction is completed based on the point cloud data of bulkheads and inner components through the BIM technology. The real-time calculation of tank capacity in different attitudes is done through the 3D model of tank. The proposed method is evaluated through the point cloud data of a complex tank in Shanghai. The research results show that this method can be used to quickly and accurately acquire tank capacities in different attitudes with high reliability and high practical application value.
