空中三角测量成果位置精度检测创新方法与实践

Practice and Innovation of Position Accuracy Inspection of Aerial Triangulation Results

为快速保障新型基础测绘航空摄影数据质量检验工作,提升大范围空中三角测量成果质检工作效率,结合新型基础测绘空中三角测量成果检查与验收实际案例,探讨了空中三角测量成果位置精度检验的内容与方法;补充细化了内外业检测点采集、位置精度统计等现有检验标准相关内容;分析了影响空中三角测量成果质量的主要因素;针对发现的问题,提出了符合现阶段实际需求的质量控制方法,为后期类似成果质量检验提供了经验借鉴。

In order to quickly guarantee the quality inspection of aerial photography data of new basic surveying and mapping and improve the quality inspection efficiency of large-scale aerial triangulation results,we discussed the content and methods of aerial triangulation result position accuracy inspection based on the actual cases of aerial triangulation result inspection and acceptance of new basic surveying and mapping,supplemented and refined the relevant content of existing inspection standards,including indoor and outdoor inspection point collection,and precision statistics standard process.Then,we analyzed the main factors affecting the quality of aerial triangulation results,and put forward quality control methods that met the actual needs of the current stage according to the problems found,providing experience for the quality inspection of similar results in the later stage.
