研究目的
Investigating the application of unmanned aerial vehicles (UAVs) for photogrammetric studies, including the development of orthophotomaps and numerical models of land cover.
研究成果
The study confirmed the advantages of photogrammetry over other geodetic measurement methods, allowing for the registration of large areas in a short time and at a low cost. The use of UAVs for photogrammetric purposes is highly effective, providing detailed and accurate results. However, attention must be paid to meteorological conditions and the use of photomultipliers for enhancing accuracy.
研究不足
Meteorological conditions such as precipitation and strong wind can hinder UAV incursions. The quality of images can be affected by large clouds reducing contrast. The processing time increases with the number of images taken.
1：Experimental Design and Method Selection:
The study utilized a UAV equipped with a camera and specialized software for photogrammetric processing. The mathematical basis of aerotriangulation was applied to process a series of images.
2：Sample Selection and Data Sources:
The study area was a peninsula located on one of the water reservoirs of the Wa?eckie — Zamkowy lakeland, covered by 73 images.
3：List of Experimental Equipment and Materials:
DJI Phantom 3 Advanced UAV, Sony EXMOR 1/2.3" matrix camera, Huawei P8 Lite smartphone, DJI GO, Ctrl+DJI, and Pix4D Capture software, Packard Bell Easynote TS11HR computer, Pix4D Mapper Pro software, Leica VIVA GS10 receivers, Leica CS15 controllers, Leica GLS30 telescopic poles, Leica AS10 SmartTrack antennas.
4：3" matrix camera, Huawei P8 Lite smartphone, DJI GO, Ctrl+DJI, and Pix4D Capture software, Packard Bell Easynote TS11HR computer, Pix4D Mapper Pro software, Leica VIVA GS10 receivers, Leica CS15 controllers, Leica GLS30 telescopic poles, Leica AS10 SmartTrack antennas.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The UAV flight was planned and executed using Pix4D Capture, images were processed using Pix4D Mapper Pro to generate orthophotomaps and numerical models of land cover.
5：Data Analysis Methods:
The quality of the orthophotomap and numerical model was analyzed by comparing them with orthographic images available on Google Earth.
