摘　　要：针对大型设备标定时对北操作复杂,不利于实际操作的缺点,文中从系统标定采用对北的基本模式出发,详细推导了免对北的系统标定算法。仿真结果表明免对北系统标定算法可行,标定精度满足一般工程应用需要,提高了大型标定设备的使用性能。In view of difficult operation of large equipment due to complex operation for its north reference,based on basic system calibration with north reference,the system calibration without north reference was deduced in detail. The results show that the method is practicable,it improves the usability of calibration equipment,and meets the need of general engineering application in calibration accuracy.
