The innovative mobile multi-touch navigation, positioning and DMT Pilot 3D 3D-documentating system developed by the German company DMT GmbH & Co. KG in cooperation with the Institute of Optical Sensor Systems at the German Center for Aviation and Cosmonautics in Berlin is presented in the article. Examples of successful commercial use of the system are given. The main objective of the project is the development of inexpensive passive measuring system that accurately tracks its own movements and operates without external references, for example, to satellite navigation systems or to databases of the accumulated cartographic material. Due to this, it is especially effective in the mines, tunnels or inside the industrial installations. In addition, real-time navigation data after additional processing can also be used for 3D documenting of the area under study, in particular, abandoned mine workings. The system consists of the cable-connected sensor head and the computational unit in the form of the data tablet or rucksack. The computational unit controls the sensor head with the help of the special software, which is based on the navigation module, which allows calculating the position of the device in real time. Processing of the accumulated information about the 3D-object allows to generate the three-dimensional cloud of points, which either is tied to the measuring navigation system, or transformed by the corresponding algorithms into the system of higher level. At the final stage, this data is transformed into the continuous model.
