摘要
针对当前在水上水下一体化测绘内业实际生产中遇到的边岸地面点提取、测量空白区弥补等问题,主要依托TerraScan模块,研究和分析了边岸地面点云提取参数的选取以及通过构建不规则三角网修补和内插测量空白区等高线的方式,提出了消除空白区的辅助性技术。在此基础上,对于水上水下一体化成图流程提出了新的等高线修测方案,完善了整个生产流程,大幅减少了生产过程中人力、物力支出,提高了一体化测绘的精度与效率以及水上水下一体化数字成果的准确性与专业性。
In view of the problems such as the extraction of ground surface points and the compensation of blank areas in the actual production of integrated surveying and mapping in water and above, we analyzed and studied the selection of extraction parameters of ground point cloud and the data filling in the measuring blind spot. On the basis of this, we put forward a technical process for the interior production of integrated surveying and mapping in water and above, which could reduce the manpower and material expenditures in the production process drastically, and enhance the accuracy and efficiency of the digital results of integrated surveying and mapping in water and above.
