摘要
本文针对大比例尺地形图传统数学精度检验工作中内外业分离、效率不高且易出错等问题,提出内外业一体化的数学精度实时检测与评定方法。通过移动智能终端与全站仪之间建立实时通信,对现场检测坐标与受检成果特征点进行自动匹配,并利用简编码过滤候选匹配点以提高自动匹配准确率,最后开发软件对全流程进行了实现。在质检项目中测试了内外业一体化模式的工作效率,并验证了同名点自动匹配过程中简编码过滤对准确率的提升效果。与传统检验手段相比,该方法效率高,易回溯,且在高程检测中可减少内插对结果造成的影响。
Aiming at the problems of separation of internal and external industries,low efficiency and error-prone in traditional position accuracy inspection of large-scale topographic maps,this paper proposes a real-time detection and evaluation method of position accuracy integrating internal and external industries.The real-time communication between the mobile intelligent terminal and the total station was established to automatically match the field detection coordinates with the feature points of the detected results,and the simple coding was used to filter the candidate matching points to improve the automatic matching accuracy.Finally,the software was developed to realize the whole process.In the quality inspection project,the working efficiency of internal and external industry integration mode was tested,and the improvement effect of simple coding filtering on accuracy in the process of automatic matching of points with the same name was verified.Compared with the traditional inspection methods,this method has high efficiency,easy backtracking,and can reduce the influence of interpolation on the results in the elevation detection.
