针对现有的三维激光扫描系统采空区地理坐标定位方法存在的设备移动困难,测量环境要求高,安装拆卸工序繁琐等问题,对三维激光扫描系统在地下采空区环境下的地理坐标定位原理和定位方法进行了研究,提出了一种基于三脚架支撑的轻便、简捷、高效的坐标定位方法。设计了一种现场试验方案,对该方法的数据处理精度进行验证,并采用该方法对采空区进行实地精准探测。结果表明：①基于该方法获得的数据模型与基于现有方法获得数据模型在空间位置上具有很高的吻合度,2种模型间的体积差在工程精度范围内可忽略不计,基于三角架坐标定位法具有与现有的坐标定位方法具有基本一致的工程精度；②采用该方法获得的探测数据构建了采空区精确三维模型,能够为采空区治理提供有价值的参考数据。上述研究结果进一步表明,基于三脚架地理坐标定位法具有设备搬运、组装和拆卸简便等优点,有助于解决现有坐标定位方法所存在的问题,对于提高采空区三维激光扫描的工作效率具有一定的效果。

In view of the problems such as difficulty in equipment moving,high requirements for measuring environment and the complicated process of the equipment installment and remove that exist in the process of georeferenced coordinate set-ting of goaf by using the existing three-dimensional scanning system,the georeferenced coordinate positioning principle and co-ordinate positioning method of the three-dimensional scanning system under the complicated environment of mine goaf are re-searched. A portable,concise and efficient coordinate positioning method based on tripod support is introduced. A field test plan is designed so as to verify the data processing precision of the method,besides that,the new coordinated positioning method is adopted to conduct field accurate detection on mine goaf. The research results show that:①the spatial locations of the data model obtained by the new coordinate positioning method have good alignment with that by the existed coordinate positioning method. The volume differences between both models is very small,which can be neglected within the scope of engineering pre-cision;The engineering precision of the new coordinate positioning method based on the tripod support is basically identical to that of the existed coordinate positioning method;②based on the detection data obtained by using the new coordinate positio-ning method,the accurate three-dimensional model of goaf is established,which can provide valuable reference data for mine goaf governance. The above research further show that,the new georeferenced coordinate positioning method based on tripod support has the advantages of easily handling,assembly and disassembly,and it is good for solving the existing problems of co-ordinate positioning method and improving the efficiency of the three-dimensional scanning on cavity.
