摘要
针对目前采煤工作面手工编录方法在效率和精度等方面存在的问题,提出了一种基于近景摄影测量理论的数码影像地质编录方法,该方法采用专门设计的摄影装置快速获取工作面影像,数据处理时,通过断面计算、影像畸变校正与镶嵌、展示影像量测、产状计算与属性描述,实现了施工地质编录方法的手工作业向计算机辅助作业与信息管理的转换。实际应用表明,与现有手工方法相比,利用此方法提高了工作面地质编录的工作效率、完整性、准确性,并有利于提升管理的自动化水平。
In view of the problems in efficiency and accuracy of manual geological logging approaches for coal mining face,this paper proposed a digital photographic geological logging method based on close range photogrammetry. This method took images of the mining face rapidly by a photographic apparatus of special design. During data processing,section calculation,image distortion correction and mosaic, display image measurement,occurrence calculation and attribute description were implemented;therefore,the construction geological logging method was converted from manual work to computer-aided work and information management. The application indicated that the method proposed by this paper had highly improved the efficiency,integrity and accuracy of geological logging of coal mining face,as well as the management automation level in contrast with manual approaches.
