Applicability of SLAM (simultaneous localization and mapping) technology for mine surveys and subsequent 3D modelling of post-extracted surfaces is assessed. The resulting surface geometry is validated via terrestrial laser scanner (TLS) acquired reference data. Typical discrepancies remained within 2 and 5 cm in horizontal and vertical directions, respectively. Discrepancies between TLS, SLAM-enabled handheld scanner and conventional surveying results are small and fully satisfy the contemporary accuracy requirements, yet evidence that the conventional mine survey results are affected by the subjectivity of the surveyors. The SLAM-enabled laser scanning hence appears to be the most suitable method for underground mining surveys.

使用支持 SLAM 的手持式激光扫描仪在地下矿山勘测中取得进展

评估了 SLAM(同时定位和映射)技术在矿山勘测和后续提取后表面的 3D 建模中的适用性。由此产生的表面几何形状通过地面激光扫描仪 (TLS) 获取的参考数据进行验证。水平和垂直方向的典型差异分别保持在 2 和 5 厘米以内。TLS、支持 SLAM 的手持式扫描仪和传统测量结果之间的差异很小,完全满足当代的精度要求,但有证据表明,传统的矿山测量结果受到测量员主观性的影响。因此,启用 SLAM 的激光扫描似乎是最适合地下采矿调查的方法。
