Simplification and Compression Construction of 3D Model for Substation

Aiming at the characteristics of complex scene and numerous equipment in substation, a simplification and compression construction method for 3D model of substation has been proposed. The 3D model has been constructed based on the substation building and equipment hierarchy, and the model vertex has been simplified according to the different precision requirements of equipment operation and maintenance. A model data compression algorithm with high compression ratio and compression efficiency is proposed to reduce the storage space of complex product model. Finally, a B/S deployment architecture of model simplification services has been designed and implemented, which can meet the needs of complex 3D model scene construction of substation.
