针对传统水库地形测绘分水上水下工程分别实施,其工程量大,效率低,存在难测、漏测区域等问题,本文提出基于VSur-W的船载移动测量方案.通过具体工程案例和精度评定实验对该系统的适用性进行了分析和实践验证.结果表明:该系统可同步采集坐标系统统一、拼接无缝的水上水下地形地貌点云数据,测绘效率高,成果丰富,一体化测量精度可达到1:2000地形图要求,在水库地形测绘中具有广阔的应用空间.%Aiming at the problems of traditional reservoir topographic surveying, such as underwater engineering and upon water engi-neering implemented respectively, large-scale engineering, low efficiency, difficult to measure and missing area, VSur-W ship borne mobile surveying scheme was proposed. The applicability of the system is verified by the concrete engineering case and the precision e-valuation experiment. The results show that the system can acquire the coordinate data of the topographic and topographic points in a u-nified and seamless manner. The surveying and mapping efficiency is high and the results are rich. The integrated measurement accura-cy cans reach 1: 2000 topographic map.
