摘要
地质探洞三维重建是抽水蓄能电站工程地质工作数字化的基础。该文针对地质探洞建模面临的特殊挑战,全面系统地提出了一套从光照补偿、数据采集到数据处理的三维重建方案,有效攻克了弱纹理地质探洞三维建模的技术难题。通过精度评估和对比分析,结果表明重建模型不仅能够满足精度要求,而且在纹理细节上展现出清晰、完整且高度逼真的效果,为后续工程的规划、设计、施工提供了高效、准确和可靠的地质信息支持。
3D reconstruction of geological exploration tunnels is the foundation for the digitization of geological work in energy storage power station projects.This article proposes a comprehensive and systematic 3D reconstruction scheme from lighting compensation,data acquisition to data processing to address the special challenges faced by geological exploration tunnel modeling,effectively overcoming the technical difficulties of weak texture geological exploration tunnel 3D modeling.Through accuracy evaluation and comparative analysis,the results show that the reconstructed model can not only meet the accuracy requirements,but also show a clear,complete and highly realistic effect on the texture details,which provides efficient,accurate and reliable geological information support for the planning,design and construction of subsequent projects.
