1. the total powerstation large-scale extra large frock of combining with 3 D laser scanning is for a measuring method, it is characterized in that:

  • take following steps;

    a, lay around large-scale extra large frock is standby the control survey point can measuring its all sites, and any two adjacent control survey point intervisibilities;

    B, the elevation coordinate of employing high-precision level to control survey point are measured, and are adopted the horizontal coordinate of total powerstation to control survey point to measure, and obtain the volume coordinate of control survey point;

    C, freely establish survey station to set up three-dimensional laser scanner, and its target is evenly distributed on around survey station, ensures that the target quantity of the same name between any two neighboring stations is greater than 3;

    D, three-dimensional laser scanner send signal, measurement target and large-scale extra large frock are for the distance between outside surface each point and three-dimensional laser scanner, and by this oblique distance angular amount relation in space, calculate target and the large-scale extra large frock volume coordinate for outside surface each point;

    E, total powerstation utilize the volume coordinate of control survey point to measure for the volume coordinate of pad target of the same name and large-scale extra large frock;

    F, the target volume coordinate of the same name that target and large-scale extra large frock record for volume coordinate and the total powerstation of outside surface each point is imported leica cyclone points cloud processing software, the cloud data of each survey station is carried out the point cloud matching based on target by three-dimensional laser scanner, and by revising the volume coordinate of target of the same name, improve the matching precision of overall some cloud;

    G, based on the cloud data after having mated, click with leica cyclone points cloud processing software and record the pad of large-scale extra large frock for concealed location.
