基于Python实现正射影像图的质量检查与精度统计方法研究

Research on DOM Quality Inspection and Precision Statistics Based on Python

DOM成果质量检查是数字测绘成果质量检查的核心内容之一,本文介绍了DOM质量检查主要的核查内容、方法和评估公式,提出了利用Python语言和FME模板设计对质量检查中需要人工核查的重要环节进行技术优化,实现检查图、表等统计信息的自动化生成,并对流程优化过程中的重要环节进行阐述,有效地提高了DOM成果质量检查效率。

The accuracy of DOM is one of main content in quality inspection of digital surveying and mapping achievements. Primary check content and evaluation formulaeare presented. Based on Python scripts and FME modelsdesign, the core manually - operated process in data inspection optimization is developed. Optimizing program which could automatically generate statistical information such as inspection report and chartistdemonstrated in detailand proved effectively in improving the efficiency of DOM products accuracy check.
