Abstract

This paper presents a method for the automatic identification of wiring routing and electrical topology of large aircraft harnessing mock-ups. This task constitutes one of the initial steps of an enrichment process that seeks to add electrical information to the 3D geometrical representation of the mock-ups in order to perform thermal and electrical simulations with them. The proposed solution uses spatial partition techniques of the scene containing the mock-up, combining both octrees and voxels. This method analyses large mock-ups and offers a good resolution of the wire routing with a low execution time. Results of the implementation are presented and compared with similar algorithms that use alternative partitioning techniques.
