Research on Binary Compression of VRML File for Power Transmission Patrol Inspection Visualization
摘要
Abstract
Virtual reality modeling language(VRML)is a primary file format used in power visualization systems for transmitting 3D models.In the context of transmission line inspection and maintenance,existing VRML files often exhibit large data volumes and complex structures,resulting in low compression rates and limited transmission efficiency.To address these challenges,a binary compression encoding method for VRML files is proposed in this paper.By employing structural hierarchy parsing,attribute difference marking,and a local consistency compression strategy,the proposed method effectively eliminates redundant node structures and point attribute data.Experimental results show that,under optimal compression conditions,the method achieves a compression ratio of up to 26∶1 on typical inspection models,significantly outperforming traditional general-purpose compression tools,while preserving the visualization quality and structural integrity.These results confirm the method's practicality and strong potential for engineering deployment.关键词
