The invention discloses a retrieval method based on a domestic aircraft information composite search
system, which belongs to the technical field of commercial aircraft digital-analog, and comprises the following steps: S1, starting digital-analog extraction
automation, S2, extracting digital-analog geometric information, S3, extracting digital-analog three-view information, S4, constructing a digital-analog feature
library, and S5, performing geometric search, three-view search and composite search. The retrieval method of the
system aims at solving the problems that the efficiency of digital-analog search is low and the aircraft
design process is accelerated through compound search of digital-analog geometric search and three-view search. According to the method, geometric information and view information are automatically fused through an
algorithm, accurate matching is ensured, designers can more accurately master manufacturing design details of the aircraft digital-analog
assembly and rapidly access and analyze geometric and view features of the digital-analog
assembly, and powerful support is provided for effectively improving the design quality and accelerating the aircraft
design process.
