中文摘要:
      针对重大装备测量中,测量点分散、坐标测量精度要求不尽一致的现实情况,提出了多边法空间坐标测量网络的精度自适应构建方法,能实现快速、低成本地构建同时符合不同测量点不同坐标测量精度要求的测量网络。方法根据测量点的概略坐标及坐标测量精度要求,使用改进的“免疫克隆算法”搜索网络布局,即首先随机生成若干组初始网络布局,然后计算初始布局测量网络下各测量点的理论坐标测量精度与要求的坐标测量精度之间的差值,并在差值较小的若干组网络布局的基础上生成新的初始布局,重复上述过程,直至所得布局测量网络能满足所有测量点的坐标测量精度要求。所提方法提高了网络的构建效率,降低了网络的构建成本。
英文摘要:
      There are always lots of scattered points need to be measured during the measurement of major equipment. And sometimes the requirements of measurement accuracy of the points are different. To build the coordinate measuring network fast and at low cost under the condition of meeting the points’ measurement accuracy requirements, the precision adaptive building method is proposed. The method searches optimization network layout by using improved immune clone algorithm. Specifically, a number of initial network layouts randomly is generated, the differences of the theory measurement accuracy and the required measurement accuracy of the points under the networks with the initial layouts are calculated, the new initial network layouts on the basis of the network layouts owning small differences are generated and the above processes are repeat until the optimization network meets the requirements of measurement accuracy of the all points. The proposed method can improve the efficiency and reduce the cost of network’s construction.
