A low-cost, easily transportable Mobile Mapping System (MMS) was designed and built to obtain the direct georeferencing parameters of images; its components are a GPS receiver, a digital compass and a digital camera. The main aim of the system is to directly define the orientation parameters of an image. The accuracy of the 3D coordinates of the points belonging to the object photographed is a consequence of the whole process which involves GPS positioning, compass angle determination, system calibration and any other useful auxiliary data that can be used to improve the accuracy of the system (GCPs coordinates, distance between the object and the camera, etc.). The tests carried out up until now have demonstrated the “theoretical”huge potential of the measuring system as well as its versatility. such as cars, helicopters and boats.
