Abstract: Quick fix technology for hydraulic turbine runner is one of the bottlenecks exerts adverse influence on operation efficiency and economic efficiency of hydropower station. Based on digital photogrammetry technology, space reverse engineering technology is proposed in this paper to realize fast digital measurement for the runner as well as digital modeling which provides the basis for maintenance and defects treatment. The paper introduces the digital measurement, digital modeling and repair process based on v-stars digital photogrammetry technology. It is of great value in further study and application.

Key words: hydraulic turbine runner, digital photogrammetry technology, reverse engineering, modeling
