【摘要】：為解決露天采場安全監(jiān)測中觀測困難、效率低下等問題,結(jié)合引用三維激光掃描和無人機(jī)傾斜攝影等三維測量技術(shù)開展露天采場安全監(jiān)測融合應(yīng)用研究。通過應(yīng)用研究表明:2類技術(shù)結(jié)合應(yīng)用可實(shí)現(xiàn)露天采場生產(chǎn)環(huán)境信息完整三維數(shù)據(jù)采集;通過統(tǒng)一控制點(diǎn)坐標(biāo)系和基于點(diǎn)云特征點(diǎn)的迭代最臨近點(diǎn)配準(zhǔn)算法(ICP)可有效融合2類點(diǎn)云數(shù)據(jù),能構(gòu)建高時(shí)效、高精度、高分辨率的采場三維點(diǎn)云模型;融合的三維模型能直觀再現(xiàn)采場生產(chǎn)環(huán)境,多尺度精準(zhǔn)監(jiān)測安全隱患問題,有效輔助采場生產(chǎn)安全規(guī)劃;該技術(shù)方案彌補(bǔ)了人工安全監(jiān)測缺陷,提高了安全監(jiān)測效率,可適用于礦山尾礦庫、水電大壩等其他危險(xiǎn)源安全監(jiān)測應(yīng)用。
[Abstract]:In order to solve the problems of difficult observation and low efficiency in safety monitoring of open-pit stope, Combined with 3D measurement techniques such as 3D laser scanning and UAV tilt photography, the fusion research on safety monitoring of open pit stope is carried out. The results show that the combination of two types of technology can realize the environmental information of open pit production. Complete 3D data acquisition; Through the unified control point coordinate system and the iterative nearest point registration algorithm based on the point cloud feature point, two kinds of point cloud data can be fused effectively, which can be used to construct the 3D point cloud model with high time-effect, high precision and high resolution. The fusion 3D model can directly reproduce the stope production environment, multi-scale accurate monitoring safety hidden trouble problem, effectively assist stope production safety planning, the technical scheme makes up for the artificial safety monitoring defects, and improves the safety monitoring efficiency. It is suitable for safety monitoring of mine tailings, hydropower dams and other dangerous sources.
