【摘要】：礦區(qū)建筑物或構(gòu)筑物變形監(jiān)測是保證礦山安全開采的一項重要內(nèi)容，傳統(tǒng)變形監(jiān)測方法效率低、安全性低、人力及時間耗費多。三維激光掃描技術(shù)具有掃描速度快、效率高及非接觸的特點，能夠保證作業(yè)人員的安全，并能獲得海量的目標點云數(shù)據(jù)。 本文將三維激光掃描技術(shù)應用于建筑物變形監(jiān)測中，充分利用其技術(shù)優(yōu)勢，對祁東煤礦主井井架進行掃描，獲取了海量點云觀測數(shù)據(jù)，并對觀測數(shù)據(jù)進行拼接、建模，在此基礎上對礦區(qū)井架進行了變形監(jiān)測的研究，取得成果如下： 1、結(jié)合國內(nèi)外現(xiàn)有研究成果，制定了適合祁東煤礦主井井架變形監(jiān)測的技術(shù)方案及數(shù)據(jù)預處理的步驟，并針對本文獲得的井架數(shù)據(jù)找到了合適的分析算法。 2、在處理好的點云數(shù)據(jù)中，根據(jù)變形監(jiān)測的要求，提取特征點用于比較兩期數(shù)據(jù)之間特征點的沉陷變化量和平面位移變化量，計算斜率比較腳架之間角度變化量，并繪制圖表以直觀顯示。 3、對計算結(jié)果進行誤差分析，分析研究了三維激光掃描技術(shù)的主要誤差來源及其減小誤差的措施。 根據(jù)本文處理結(jié)果得到如下結(jié)論：三維激光掃描技術(shù)能夠應用于變形監(jiān)測中，能提高工作效率，，數(shù)據(jù)量也比傳統(tǒng)的變形監(jiān)測詳細，但是其精度還不能夠滿足變形監(jiān)測的要求，還需在硬件和軟件方面加以深入研究，以克服以上問題。
[Abstract]:Deformation monitoring of buildings or structures in mining area is an important part of mine safety mining. The traditional deformation monitoring methods are inefficient, low safety, labor and time consuming. 3D laser scanning technology has a fast scanning speed. The characteristics of high efficiency and non-contact can ensure the safety of operators and obtain massive target point cloud data. In this paper, the 3D laser scanning technology is applied to the deformation monitoring of buildings, and the main well Derrick of Qidong Coal Mine is scanned by making full use of its technical advantages. The massive observation data of point cloud are obtained, and the observed data are jointed and modeled. On this basis, the deformation monitoring of mine Derrick is studied, and the results are as follows:. 1. Based on the existing research results at home and abroad, the technical scheme and data preprocessing steps for monitoring the deformation of main shaft Derrick in Qidong Coal Mine are established, and an appropriate analysis algorithm is found for the Derrick data obtained in this paper. 2. In the processed point cloud data, according to the requirements of deformation monitoring, the feature points are extracted to compare the changes of subsidence and plane displacement between the feature points of the two periods of data, and to calculate the angle changes between the scaffolding compared with the slope. And draw the chart to visualize the display. 3. The error analysis of the calculation results is carried out, and the main error sources of the 3D laser scanning technology and the measures to reduce the errors are analyzed and studied. According to the results of this paper, the following conclusions are obtained: 3D laser scanning technology can be used in deformation monitoring, can improve the working efficiency, and the amount of data is more detailed than the traditional deformation monitoring, but its accuracy can not meet the requirements of deformation monitoring. Further research on hardware and software is needed to overcome the above problems.
