Abstract: | Recently, the interest in Unmanned Aerial Vehicle (UAV) application in photogrammetric
environment has increased in many countries. The fixed-wing UAV, the model of
EPP-FPV with mounted digital camera Canon S100 was used as a platform for images acquisition. Implemented means are low-cost, mobile and simple. Digital photogrammetry technology with Pix4D software application has been applied for UAV images processing and
area mapping. High quality of images is a significant factor for the efficiency and accuracy
generating standard mapping products. The correctness of digital surface models and
orthophotos mainly depend on camera resolution, flight height and ground control point
(GCP) accuracy. The paper reports on investigations how number of GCPs used for UAV
image transformation influences the mapping results. The demand of such investigations
arises because the flight paths with a fixed wing UAV have general form, in contrast to classical paths which are pricewise straight lines, as well as the flight significantly depends on
weather conditions (especially on wind) and the platform shows considerable tilt because
of its light weight. The results of DSM accuracy investigation demonstrate the quality of
UAV Photogrammetry product with the use of appropriate number of GCPs |
