ABSTRACT
Obtaining photogrammetric data such as digital images or laser point clouds using a plane or a helicopter is already very common. These methods are used in case of large surface areas. For several years, experiments using a variety of unmanned aerial vehicles (UAV) for measurements have also been carried out. However, the UAVs are capable of imaging very small objects (point object) with the use of non-metric cameras, while gyrocopters, compared with currently used aircraft are characterized by: high maneuverability and low minimum speed-through, much lower costs of purchase and use, and ease of transport. Therefore, they are used wherever the use of both plane, and helicopter, as well as ground-based measurements is uneconomical. This article presents an initial attempt to assess the quality of the photogrammetric data obtained from gyrocopter. GPS/INS data, images from digital camera and point clouds from airborne laser scanner are analyzed considering the stability of the flight of gyrocopter and hence the quality of the obtained data, and their usefulness in generating further products, such as digital terrain models, orthophotomaps, or 3D buildings models. The results provide information necessary at the stage of planning photogrammetric mission with the use of gyrocopter.
