基于Pix4D Mapper的无人机数据处理

Pix4D Mapper-based UAV Data Processing

随着无人机技术以及数字摄影遥感技术的发展,越来越多的无人机内业处理软件如雨后春笋般出现在市场中,其中Pix4D Mapper以其出色的处理正射影像的质量和速度得到航测市场的青睐。本研究以Pix4D Mapper为例,对大疆精灵4RTK数据处理得到数字正射模型DOM,利用南方CASS9.1根据DOM进行数字线划图DLG的绘制并对成果进行精度验证分析。验证结果表明:所测的9个点的平面误差均在±5 cm以内,最大点的误差为5号检查点的Y方向上为4.9 cm,最小的误差为6号点Y方向上的误差1.2 cm,可为实际项目作业提供参考。

With the development of UAV technology and digital photography remote sensing technology,more and more UAV interior processing software have sprung up in the market.Pix4d Mapper is favored by the surveying and mapping aerial survey market for its excellent quality and speed in processing orthophoto images.In this study,the aerial survey processing software pix4d mapper is taken as an example to process the indoor data of DJI Phantom 4 RTK to get the dom of digital orthophoto model.The South cass9.1 is used to draw the DLG of digital line drawing according to the DOM,and the accuracy of the results is verified and analyzed,which provides a reference for the actual project operation.The verification results show that the plane error of the measured 9 points is within±5 cm,the maximum error is 4.9 cm in the Y direction of checkpoint 5,and the minimum error is 1.2 cm in the Y direction of checkpoint 6,which can provide a reference for the actual project operation.
