Controle estatístico de processo aplicado à GCP’s em mapeamento aerofotogramétrico com uso de vant

The use of Unmanned Aerial Vehicles (UAVs) is rapidly growing in several areas of knowledge. Its wide use is due to the ease of adaptation that these equipments offer to the needs of each project, since the characteristics of the images are directly related to parameters such as resolutions, scales and types of sensors, which are chosen according to the need of each work. Although advances in photogrammetry today offer great cost advantages, an intuitive and effective approach to 3D modeling, little is known about which sensor and which software will produce results that can effectively meet users'' requirements. The objective of this work was to analyze the errors of the process involving the RTK (Real Time Kinematic) model used in the collection of GCP points and to evaluate the quality of the process presented by the software Pix4D, having as a data base for evaluation the error report presented by Software for GCPs. Both the horizontal and vertical errors of the RTK model, as well as the errors presented by the coordinates X, Y and Z given by the Pix4D were within the limits of control, indicating, therefore, that in this case the process is under control. Control limits were lower than GSD size.
