摘　　要：提出一种面向高边坡全息监测的旋转多基线数字近景摄影测量方法。通过对非量测相机进行精密检校,采用多周期旋转多基线方式对边坡进行摄影,构成连续像对,采用光束法平差生成边坡高密度三维点云数据序列,实现对边坡变形全息监测。试验表明:该方法获取的点位精度最优达到0.9毫米,具有较好的精度和可靠性,能够满足工程的应用要求。The paper proposed a rotating multi-baseline digital close-range photogrammetry method for high slope holographic monitoring.Through the precision calibration of the non-measuring camera,the multi-cycle rotating multibaseline method is used to photograph the slope,and the continuous image pair is formed.The high-density three-dimensional point cloud data sequence of the slope is generated by the beam method to realize the slope deformation Holographic monitoring.The experimental results show that the accuracy of the method is 0.9 mm,which has good accuracy and reliability,and can meet the requirements of engineering application.
