三维地理实体数据质检系统的设计与实现

Design and Implementation of Quality Inspection System of 3D Geographical Entity Data

传统的三维地理实体数据检测方式主要以人机交互的方式进行,效率低、精度差、人为影响较大,不能满足大规模三维实体数据生产的需要。因此,该文设计并实现一款三维地理实体质检系统,并应用于实际工程中。结果表明,该系统能够实现三维地理实体数据数学精度及质量的自动化检测、支持质检记录的回溯查看以及质检结果的汇总评分、质检记录和质检报告的自动化输出等功能,避免了质检过程中人为因素的影响,提高了工作效率,维护了质检工作的规范性。

The detection method of traditional 3 D geographic entity data is mainly in the way of human-computer interaction,it is low efficiency,poor accuracy and great human influence,so it can not meet the needs of large-scale 3 D entity data production.Therefore,this paper designs and implements a three-dimensional geographic entity quality inspection system and applies it to practical engineering.The results show that the system can realize the automatic detection of the mathematical accuracy and quality of 3 D geographic entity data,support the retrospective view of quality inspection records and the summaring and scoring of quality inspection results,and the automatic output of quality inspection records and quality inspection reports.It avoids the influence of human in the quality inspection process,improves the work efficiency and maintains the standardization of quality inspection work.
