Investigation of Pix4Dmapper automatic data-processing technology in unmanned aerial vehicles

Remote sensing by unmanned aerial vehicles (UAVs) is widely used in various fields due to of its advantages of high mobility, timeliness, high resolution, and low cost. However, due to the characteristics of UAVs and the limitations of traditional data-processing technology, UAV data processing has become a major problem in UAV applications. In this paper, we discuss the combination of UAV automatic data-processing technology with Pix4Dmapper software, and apply this concept to actual work. We investigate the use UAV remote sensing data in aerial triangulation computation, adjustment calculations, orthophoto corrections, and mosaic automatic processing technology. The results show that UAV data are quickly stitched and calibrated and an orthophoto map generated, which technically supports the rapid and automatic processing of UAV data.
