Ground-based laser scanning is a modern technology that allows you to obtain automatically information about the spatial position of a large number of points belonging to the surface of the object being shot. In the oil and gas industry, ground-based laser scanning has shown its high efficiency in the process of measuring the geometric parameters of reservoirs for storing oil and oil products. For the full use of this technology today a number of laser scanning techniques for tanks have been developed and indicated in the regulatory documentation of the Russian Federation. At the same time, these methods have some drawbacks that lead to problem situations when it is necessary to conduct laser scanning of tanks in difficult and / or cramped conditions, which are especially typical for tank parks of marine terminals. In addition, these methods do not allow a flexible search for the optimal layout of scanner stations in the presence of requirements for the error of the measurement results. To eliminate the disadvantages inherent in current methods, the authors developed a simple mathematical apparatus that allows to develop a layout of the scanner stations and determine the appropriate boundaries of the scanned sections of the tank surface within the presence of a significant number of structures that impede the direct visibility of the scanned surface of the tank, and when performing work in cramped conditions without the need for complex calculations. In addition mathematical apparatus makes possible to conduct a flexible search for the optimal layout of the scanner stations in the presence of specific requirements for the permissible measurement error during laser scanning of the tank and to determine the measurement error for the selected layout of the scanner stations.
