摘　　要：为满足工程施工地质编录的信息化需求,解决开挖洞室影像采集、处理、建模及后续地质编录应用难题,通过对当前开挖洞室常用人工光源、影像采集手段、实景建模方法的分析研究,提出了基于洞室断面环状影像采集技术和空间影像信息差分技术的实景建模解决方案,并结合模型浏览器和自主开发软件,实现了实景模型地质编录功能。将该技术成功应用于陕西东庄水利枢纽工程施工洞室,结果表明:该技术以较低的影像采集成本和技术应用门槛,实现了开挖洞室实景模型构建和后续地质编录,大大提高了现场施工地质工作的效率和成果质量。研究成果可为水利工程施工实景地质编录提供参考。In order to meet the needs of geological record informationization in engineering construction and solve the application problems of excavation cavern image acquisition, processing, modeling and subsequent geological cataloging, we proposed the technical solution of cross-sectional circular photography and image position and orientation system calculation tailored for the reality modeling of caverns based on deep investigations in construction light source, photography method and reality modeling method.The consequential geology recording method was conducted on reality model viewer and self-developed program.This technology was successfully applied to a construction cavern in Dongzhuang Water Conservancy Project in Shaanxi Province.The results showed that the technique was distinguished by its lower costs in image collection and reduced barriers to technological application.It could successfully facilitate the construction of reality models and the subsequent geological recording in caverns excavation, markedly enhancing the efficiency and quality of geological work conducted on-site.The research results can provide a reference for the realistic geology recording of hydraulic engineering construction.
