Unmanned Aerial Vehicles (UAVs) have become an attractive data acquisition platform in photogrammetric applications. As we know, the fundamental photogrammetric and remote sensing problem is the determination with high accuracy of the attitude, the position and the intrinsic geometric characteristics of the sensor. At the beginning, the aerial photogrammetric systems had a fairly low accuracy position, but today’s, the new aerial photogrammetric systems allow the real-time determination of all parameters of exterior orientation with a good enough accuracy. Because of this, the advantage is that we can achieve direct georeferencing without needing to determine the coordinates of ground's control points, before or after the photogrammetric flight. In this paper I present some practical results of so called direct georeferencing of digital images, using of direct measurements of the image’s exterior orientation parameters by a GNSS/IMU system. This application is achieved by the aid of the collinearity concept, and just for a good accuracy estimation of the method, I have used few ground control points.
