【摘要】：使用三維激光掃描技術(shù)獲取沉陷區(qū)內(nèi)三層框架結(jié)構(gòu)建筑物點云數(shù)據(jù),并使用隨機抽樣一致性算法(RANSAC)提取建筑物點云正交三軸特征線,擬合滿足最小二乘情況下特征線的交點為特征點。對比兩期數(shù)據(jù)間特征點變化以獲取建筑物變形規(guī)律,并與概率積分法提取的地表移動變形規(guī)律進行對比。實驗結(jié)果表明:該方法提取建筑物變形規(guī)律與概率積分計算地表移動變形規(guī)律相近,建筑物最大下沉值700mm,整體向東北方向傾斜,傾斜角度與豎直方向呈8.8'。建筑物向東北方向最大水平移動657.78mm,與南北軸線呈28.39°,最大拉伸變形1.69mm/m。
[Abstract]:The use of 3D laser scanning technology to obtain the settlement of three storey frame structure building in the area of point cloud data, and using the random sample consensus (RANSAC) algorithm to extract building point cloud three orthogonal axis lines, fitted under the condition of least squares intersection feature lines as feature points. Comparison of the two data points between the changes in order to obtain the deformation law of buildings. With probability integral method and extract the surface movement and deformation were compared. The experimental results show that the integral calculation of surface movement and deformation of similar rules and probability of the extraction method of deformation of buildings, building the sinking value of 700mm, the overall tilt to the northeast, the tilt angle and the vertical direction is 8.8'. building to the Northeast in the maximum horizontal movement is 657.78mm. 28.39 degrees and the north-south axis, the maximum tensile deformation of 1.69mm/m.
