摘要
针对国内尚无文献研究过全站仪检定的国际标准ISO17123-5中完整检定法的数据处理方法,从平面坐标转换原理出发,推导了完整检定法水平位置检定时使用的三参数坐标系转换公式并与ISO17123-5的计算公式进行了对照;按照ISO17123-5规定的完整检定法,对徕卡全站仪TS02进行了实际检定;分别用ISO17123-5的三参数法及国内常用的四参数法对TS02的实测数据进行了处理,其结果表明:两种数据处理方法的结果是一致的。因此在实际工作中:既可以按照ISO 17123-5给出的公式进行数据处理,也可以按照国内通用的四参数转换软件对检定数据进行处理。
For solving the problem that there is no investigation in China about the processing method of data in verifying the whole total station according to international standard ISO17123-5,the formula of coordinate transformation by3-parameter,which is used for verifying horizontal position of total station,is derived based on the principle of horizontal coordinate transformation,and compared with the formula of ISO17123-5.Leica TS02total station is verified according to ISO17123-5.The data measured in verifying the whole total station TS02is respectively processed by3-parameter formula above and4-parameter formula used commonly in China.The results show that the two methods of data processing are identical.So,either the formula of ISO17123-5or4-parameter formula used commonly in China is feasible in practice.
