Application of advanced photogrammetry technologies for dimensional control based on a real project is described in the article. The research contains relative and absolute accuracy assessment of the final products and description of the possible usage of the data. The methodology comprises high speed of field data collection and good detailing level. For application of the photogrammetric approach there is no need in expensive geodetic equipment - data collection being done by standard photo camera. Utilization of the methodology helps to optimize current routines in the field of dimensional control of oil and gas facilities. Products of 3D reconstruction based on photogrammetry methods, point clouds and models draped by raster images help user to make precise measurements directly on the model. Integration of the technology into company production chains helps to cut costs of field-based part of the dimensional control process. In case when field stage of photogrammetric approach is combined with traditional survey using total station or GNSS receiver the precise coordination of 3D models in required coordinate system is possible. It has been planned to research of dependence of real objects complexity on accuracy, quality and details of created models as future development of the thesis. Better understanding of variety of object features may significantly improve the process performance and help to create accurate and detailed models with lower chance of getting bad results.
