摄影测量技术在巷道迎头面地质编录中的应用

摘要

煤矿巷道开挖出的迎头面形状不规则,且由于个别地点较危险,地质人员无法进行近距离的量测,因而难以对迎头面进行准确的编录。迎头面摄影测量方法的研究正是为了当开挖过程中遇到特殊的地质构造时,能够采用影像地质编录方法准确快速地完成地质编录。本文着重研究了拍摄巷道迎头面立体像对时使用的特殊控制手段,使其能够满足模型定向定位的需要,并研究了此种方式下立体像对的处理方法,使其能够满足影像地质编录的需要。%In the coal mine, tunnel excavating faces＇ shape is usually irregular, and some places near the tunnel excavating face are very dangerous. Geologists can not measure near the tunnel excavating face, so it is very hard to finish geological logging. The research of tunnel excavating face＇s photogrammetry is in order to complete the work quickly and accurately with the method of photographic geological logging. This paper focuses on the special means of control work and the method of image processing in order to meet the needs of photographic geo- logical logging of tunnel excavating face.
