The invention relates to the technical field of ship measurement, in particular to an efficient multi-loop large ship main ship body molded line measurement method. The invention innovatively provides a measurement method adopting a target control network under a global coordinate system, registration processing is carried out on point cloud data of each station in the global coordinate system through a total station layout target, and the problem of error accumulation caused by borrowing the position of an adjacent station relative to the target in data splicing of a three-dimensional laser scanner is ingeniously avoided; the problem that a large number of errors are accumulated due to multi-station splicing of the three-dimensional laser scanners is solved by utilizing the advantages of large measurement range and high precision of the total station. Meanwhile, a plurality of loops are arranged for three-dimensional laser scanning of the whole ship, the single-loop distance is shortened, and the error problem caused by the too large loop is reduced.
本发明涉及船舶测量技术领域,具体涉及一种高效多环路大型舰船主船体型线测量方法。本发明创新的提出了采用全局坐标系下标靶控制网的测量方法,通过全站仪布局标靶在全局坐标系对各站点点云数据做配准处理,巧妙回避了三维激光扫描仪数据拼接中借用邻站相对标靶位置导致误差累计的问题,利用全站仪测量范围大、精度高的优点消除三维激光扫描仪多站拼接导致误差大量累积的问题。同时,三维激光扫描整船设置多个环路,缩短单环路距离,减小环路过大导致的误差问题。
