内外分区空间统一精度场建立方法研究

针对内外分区空间内结构和设备安装的数字化测量需求,研究内外参考点之间的关联技术,构建与外测量精度场相统一的内测量精度场。对于内外空间不同的开口数,利用多测点定位法、二测点和水平仪单站位定位法、二测点和水平仪双站位定位法等方法建立内精度场,实现与外精度场的统一。以某型设备为例进行试验表明,利用内外精度场测量同一检测点进行比较,测量的最大不一致误差为0.14 mm,证明构建模式可行、简单、可靠。

Research of Establishing Method for Unified Accuracy Field of Internal and External Regional Space

For digital measurement demands of the structure and equipment installation in the internal and external regional space,the associate technology of inside and outside reference points is researched.The intemal measurement accuracy field united with the external measurement accuracy field is constructed.With regard to different openings between inside and outside spaces,utilizing the multi-spotting method,two measurement points and a level single-station positioning method,two measuring points and a level two-station positioning method,internal precision field is established to achieve the unity with external precision field.In a certain type of equipment,for example,experiment results show that the inconsistent measurement error of the same checkpoint between inside and outside measurement accuracy fields is up to 0.14 mm,which proves that the build mode is feasible,simple and reliable.
