摄影地质快速编录的关键技术研究

Technique study on fast log of photographic geology

针对现行水电工程、地下工程施工地质编录方法的不足,进行了摄影地质快速编录技术与方法的研究。在数字相机量测化改造的基础上,综合应用近景摄影测量、图像处理和GIS技术,设计开发了基于数字相机的摄影地质编录信息系统。该系统以高边坡、大洞室为对象,具有数字摄影、正射影像制作、图像镶嵌、编录要素提取与产状量测、编录成果CAD制图等功能,实现了数据采集、机助处理与成图的一体化作业模式,提高了地质编录的工作效率和成图精度,为施工地质编录提供了新的手段与途径。

Due to the shortage of geological log methods on hydroelectric engineering and underground engineering, the photographic methods based on digital camera were studied in this paper. Integrative application of technology of close shot photogrammetry, digital image processing and GIS, the photographic geological log information system was developed. The system has the functions of digital photography, orthoimage production, inlay image, log factors extracting and measure, CAD drawing etc. The methods can improve work efficiency and higher precision. It provides a new method for the geological log. 
