摘要
在研究多组像片内方位元素的修正和全局光束法平差的基础上，提出使用3台像机同时对测棒进行数据采集，通过光束法平差实现单点三坐标测量的新方法，并完成系统硬件的组建。通过实验，将新系统测量的结果与计量型三坐标仪测量值进行比较，得到系统的相对测量精度高于1：29061，优于单、双像机系统，能够满足工业产品的检测需求。
Based on the research correction of multi-image interior orientation and integrated bundle adjustment, a new method is proposed to perform data collection of hand-held probing device by utilization of three cameras simultaneously and to achieve single point 3 D coordination measurement by bundle adjustment, resulting in establishment of system hardware. During experiments, the relative accuracy of the new system is higher than 1 ： 29 061, compared to the measurement accuracy of the counterpart metrology CMM device. This result is more accurate than that from single camera system or Duo-camera system, and could meet the measurement requirements of industrial products.
