摘要
针对当前地理信息产品质检软件检查数学精度和要素属性正确性方面功能不足的问题,提出了基于激光点云、影像、视频、POS等多源数据联合检查数学精度和要素属性的软件系统构建方法,并从总体架构设计、数据库设计、功能设计等方面介绍了系统设计理念。实践证明,该系统检查结果可靠,能够大大提高精度检测和属性评估的效率,对地理信息产品质量控制具有重要意义。
Aiming at the problem of insufficient function in checking mathematical accuracy and correctness of element attributes in current geographic information product quality inspection software,a software system construction method based on LiDAR,image, video,POS and other multi-source data joint inspection precision and attribute is proposed.The system design concept is introduced from the aspects of overall architecture design,database design and functional design.Practice has proved that the system has reliable inspection results,which can greatly improve the efficiency of precision detection and attribute evaluation,and is of great significance for the quality control of geographic information products.
