Abstract

Last years the interest in using the airborne laser scanning systems has much more increased. One of the applications is the 3-D modeling of the scene. The promising accuracy of the airborne laser scanner measurements is usually 5 - 10 cm in X,Y, and 10 - 30 cm in the Z direction. This does not, however, fully describe the performances of the systems if a 3-D model of a target is needed. How precise and accurate will the 3-D model be, for example? How good does it fit in the real object? In order to answer these questions, a comparison of the three-dimensional models generated from the laser data acquired in different ways must be done. The cheapest and more flexible way to do it is a simulation. This paper examines scanning techniques mainly used in laser remote sensing for topographic and mapping purposes today. A simulation program has been developed for this aim. The scan patterns generated based on those like such commercially available laser scanning system as TopoSys, ALTM-1020, TopEye, and 3-D profilometer create. The program allows to change a number of flight parameters, i.e. the flight speed, the flight altitude, roll, pitch and yaw angles. Basically, the concern was the image geometry. No radiometric analyses were performed. Some example pictures presented. The results showed that the 3-D model generated from the data collected in a way TopoSys does is much accurate and informative compared to ALTM-1020 or TopEye from the point of view of the geometry.
