Abstract
The embodiment of the present application discloses a method and equipment for transformation of point cloud coordinates of structure plane of deep-buried tunnel based on a target device. Before performing laser scanning on a measured surface, the embodiment of the present application makes the third plate surface close to the measured surface by adjusting the target device, and makes the bubbles of the first circular level and the second circular level in a centered state; respectively extracting point cloud coordinates of the three cross targets from the point cloud data, and acquiring the first tendency of the third plate surface from the digital display of three-dimensional electronic compass; determining the second tendency of the third plate surface according to the point cloud coordinates; converting the coordinates in the point cloud data to geodetic coordinates according to the first tendency and the second tendency.
