MEDEIROS, Fabrício Ardais et al. On the use of unmanned aerial vehicle for acquisition of georrefecend image data. Cienc. Rural [online]. 2008, vol.38, n.8, pp. 2375-2378. ISSN 1678-4596. http://dx.doi.org/10.1590/S0103-84782008000800046.
The aim of this study consisted in developing and testing an alternative procedure for data acquisition, telemetry, monitoring and geo-referencing in agricultural fields. The proposed approach was implemented by placing dedicated electronic gear onboard Unmanned Aerial Vehicles (UAV). For this purpose an UAV was assembled at the Federal University in Santa Maria, Brazil and equipped with the required hardware for image and control points acquisition. Tests have shown that the proposed approach can be regarded as a valuable tool to detect areas affected by faulty germination, weed infestation and mapping in general. The tests have also shown that poor quality of the acquired image data was the main drawback in the equipment onboard the UAV, pointing to the need to reevaluate the system with regard to this particular aspect.
