Auxiliary recognition method for gas turbine hole inspection component based on virtual reality technology

Abstract

The invention discloses an auxiliary recognition method for a gas turbine hole inspection component based on a virtual reality technology. The method comprises the following steps of: 1, generating an original model library by using the shape and assembly data of a gas turbine component subjected to forward design or reverse surveying and mapping; 2, importing real-time hole inspection image data of the component of the gas turbine during actual hole inspection inspection into an analysis module; 3, performing feature analysis and extraction on the real-time hole inspection image of the component in an analysis module to generate a digital feature map; 4, matching a corresponding model map from the original model library according to the digital feature map, and generating a virtual three-dimensional image of the component; and 5, superposing a virtual three-dimensional image on the real-time hole inspection image, and attaching auxiliary prompt information such as component names, assembly and orientation features. According to the method, the problem that the component structure and the assembly characteristics cannot be quickly identified during hole inspection of the gas turbine at present is solved, the hole inspection efficiency of the gas turbine component is greatly improved, the reliability of the result is ensured, and technical support is provided for safe operation of a unit.

Description

Technical field [0001] The present invention belongs to the technical field of non-destructive detection, and is specifically a virtual reality technology, auxiliary recognition method based on a virtual reality technology. Background technique [0002] The aperture inspection refers to the use of specialized aperture equipment, and enters the relevant components inside the combustion engine by the reserved hole detection, and effectively mastered and evaluate the combustion engine through the reserved hole detection. Service quality and health status of each component. Regularly controlling the regularity of the combustion machine is a must-have means of safeguarding the security of the unit, and is one of the key links of the daily operation and maintenance of the combustion engine. [0003] Since the number of components in the internal parts of the combustion engine is complicated, when the assembly structure is complicated, there is a case where the structural characteristic...
