Experimental Investigations to Enhance Precision and Accuracy in UAV Photogrammetry of 3D Model

Unmanned Aerial Vehicles (UAVs) have become a popular tool for photogrammetry applications like mapping and 3D modeling. UAVs offer several advantages over traditional aerial photography, including low-cost, rapid deployment, and the ability to capture high-resolution imagery from unique angles and viewpoints. This paper studies UAV photogrammetry with technology and techniques used to capture, process, and analyze UAV imagery for mapping and 3D modeling applications. Based on the study, the importance of optimal flight planning, image processing, and data fusion techniques in improving the quality and accuracy of the data captured by UAVs is understood. The circular grid plays a vital role since it has better views when compared with rectangular grid so that while converting into 3D model, the object will be well defined.
