The invention discloses a method and device for monitoring and analyzing the deformation of a tower-type ancient building. The method includes: obtaining point cloud data of a tower-type ancient building to be measured according to a three-dimensional laser scanner; obtaining the tower-to-be-measured tower through a total station Coordinates of control points around the ancient building to establish a monitoring absolute coordinate system; the control point is a target control point arranged around the ancient building to be measured; the point cloud data is registered to the absolute coordinate system Carry out deformation processing analysis on the offset of the single column, the offset of the single layer, the overall offset, the overall inclination and the torsion of the tower-type ancient building to be tested. The invention acquires comprehensive and accurate structural data of tower-type ancient buildings, so as to formulate reasonable protection schemes early and prevent the accelerated development of deformation hazards of ancient buildings.
Description
technical field [0001] The invention relates to the field of surveying and mapping science and technology, in particular to a method and device for monitoring and analyzing deformation of tower-type ancient buildings. Background technique [0002] Three-dimensional laser scanning technology is a brand-new surveying and mapping method. It uses the principle of laser ranging to obtain information such as three-dimensional coordinates and reflectivity of a large number of dense discrete points on the surface of the measured object for all-round, all-angle, internal and external comprehensive and non-contact. It can quickly establish the 3D model of the measured object and various map data such as lines, planes, and volumes. With its advantages of high efficiency, high precision, and no contact with the ancient building itself, it has received more and more attention in the survey of ancient buildings. more and more attention. [0003] For example, take the wooden pagoda in Yin...
