基于Pix4Dmapper的应急测绘数据处理技术研究
|
摘要
为了最大程度地满足应急救灾对于时效性的要求,数据的快速高精度处理成为目前研究的热点。以Pix4Dmapper软件为平台,通过不同的处理模式完成了宁夏中卫西北工业园区航测数据的正射影像生产;并对其精度和效率进行了整体分析和评价。结果表明,根据2 000 m和1 000 m相对航高设计完成的航测相机成像作业任务,其成像数据的处理效率和精度满足应急测绘的时效性要求,可为国家和地方应急救灾紧急任务指令决策提供第一手资料和数据服务保障基础。
In order to meet the requirements of emergency response to the urgency maximumly, the rapid and high precision data processing has become a hot topic. In this paper, taking Pix4Dmapper software as a platform, we used different processing modes to complete the aerial data orthographic image production of Ningxia Zhongwei Northwest Industrial Park, and analyzed and evaluated their accuracy and efficiency. The experimental results show that according to the relative aerial height design of 2 000 m and 1 000 m, the processing efficiency and accuracy of the imaging data can meet the timeliness requirements of emergency surveying and mapping, which can provide first-hand result information for national or local emergency surveying and mapping command decision and data services safeguard.
