【摘要】：POS系統(tǒng)是移動(dòng)測(cè)量系統(tǒng)的重要組成部分。由于系統(tǒng)集成影響,POS系統(tǒng)中心的運(yùn)動(dòng)狀態(tài)無法直接觀測(cè)。因此,可采取設(shè)置相關(guān)測(cè)量合作目標(biāo)的方法,在確定其與POS系統(tǒng)中心的位置基礎(chǔ)上,通過觀測(cè)合作目標(biāo)來確定POS系統(tǒng)中心的運(yùn)動(dòng)狀態(tài)。從車載移動(dòng)測(cè)量系統(tǒng)空間基準(zhǔn)統(tǒng)一方程出發(fā),提出了一種解算測(cè)量合作目標(biāo)安置參數(shù)的方法,并以此為基礎(chǔ),系統(tǒng)分析POS系統(tǒng)定位定姿誤差、全站儀測(cè)距測(cè)角誤差、尺度因子誤差等誤差源對(duì)安置參數(shù)解算的影響,推導(dǎo)了安置參數(shù)解算的誤差模型。實(shí)驗(yàn)結(jié)果表明,采用本文解算方法,可以獲取毫米級(jí)的合作目標(biāo)安置參數(shù),滿足合作目標(biāo)應(yīng)用于動(dòng)態(tài)測(cè)量檢測(cè)POS系統(tǒng)定位精度的需求。
[Abstract]:POS system is an important part of mobile measurement system. The motion state of POS system center can not be observed directly because of the influence of system integration. Therefore, we can adopt the method of setting the cooperative target of correlation measurement, on the basis of determining its position with the center of the POS system, we can determine the moving state of the center of the POS system by observing the cooperative target. Based on the unified equation of spatial datum of vehicular mobile measurement system, a method of solving and measuring the parameters of cooperative target placement is put forward. Based on this method, the positioning and attitude error of POS system and the range angle error of total station are analyzed systematically. The effect of error sources such as scale factor error on the settlement of placement parameters is discussed. The error model of settlement parameters is derived. The experimental results show that the cooperative target placement parameters of millimeter scale can be obtained by using the solution method in this paper, which meets the requirement of the location accuracy of the cooperative target applied to the dynamic measurement and detection of POS system.
