【摘要】 本文主要是利用徕卡TCA2003系列全站仪(测量机器人)的ATR(Automatic Target Recognition)自动目标识别功能,在徕卡公司提供的二次开发环境GEOCOM下开发自动变形监测系统,将人工操作的测量工作利用计算机进行自动控制测量来完成,主要针对计算机与测量机器人之间的数据通讯、传输存储以及平差处理等领域进行了研制和开发。在观测过程中采用了极坐标实时多重差分改正模型对原始数据进行差分处理和成果输出,并对TCA2003全站仪的ATR原理和精度进行了分析。对于观测数据的事后差分处理方法进行了探讨,提出了使用平均间隙法来检验基准点的稳定性和用坐标转换法来处理测站点不稳定的情况下统一坐标系的数据处理方法。拟稳平差的方法在事后数据差分处理中也得到了很好的应用,主要是解决了无冗余观测值情况下提高测量精度,这种方法可以对与基线方向大气折光系数相近的方向的变形点的观测数据进行较为有利的改正,从而提高了变形点观测数据的精度。同时,利用Visual Basic语言开发了一系列的程序模块来实现自动测量的功能和简单的数据处理等,这对于野外观测条件恶劣和持续时间长以及重复性比较强的变形监测来说具有很大的意义,在进行相应的差分改正后,其观测精度能满足一般工程测量的要求,具有很重要的现实意义。更多还原

【Abstract】 This paper main uses the ATR (Automatic Target Recognition) function of the TCA2003 series Total Station, develop automatic distortion monitoring system under the twice developing environment of GEOCOM which is brought by the Switzerland Leica company .It uses the computer to control the automatic surveying work instead of the manual work. It main places the emphasis on the data communication, data transmission and post-process adjustment etc field. In the process of the survey, we use the model of polar coordinates multi-time difference correction to dispose the data and we also analyse the principle of the Total Station’s ATR function. It discuss the way to deal with the survey data after the survey, brings out the average clearance way to check up the datum mark’s stability. The coordinate diversion way is used to unify reference frame on condition of the station is unstable. The adjustment is used to deal with the data after the survey, it main advances the survey precision when there is no redundant observation value. This way can correct the distortion point correctly on the way of near the atmosphere refraction modulus to heighten the precision of the distortion point’s value. It develops a series of modules using the Visual Basic language to realize these functions. It places an important role in the work which has been done in the atrocious weather or long time and some repeated distortion monitoring work. The experiment proved that it’s precision can satisfy the common engineering survey, it plays an important role in fact.更多还原
