摘要
传统算法对斜坡垂直沉降量的计算,与实际勘测值存在误差,为此,提出基于近景摄影测量技术的采矿诱发斜坡移动变形计算。利用近景摄影测量技术,获取斜坡物理参数,并通过单元表达的方式,得到斜坡的移动变形值。实验结果表明,提出算法相比传统算法,提高了垂直沉降量的计算准确度。
There are errors between the calculation of vertical settlement of slope by traditional algorithm and the actual survey value.Therefore,the calculation of slope movement and deformation induced by mining based on close range photogrammetry technology is proposed.Using close range photogrammetry technology,the physical parameters of the slope are obtained,and the displacement and deformation value of the slope are obtained by unit expression.The experimental results show that the proposed algorithm improves the accuracy of vertical settlement calculation compared with the traditional algorithm.
