We write the program which used for fighting errors in absolute positioning. we also write the program which used for linear combinating in absolute positioning. from analyzing for the measurement of outer, we can conclude that we can use m estimation to estimate parameter in gps absolute positioning. lt has application value. using it, we can obstain the stable positioning result and remove the outer. in this paper, we calculate the data which from the baseline space of the gps calibration space. we also draw some conclusion using broadcast ephemeredes and smoothing pseudoranges. the positionging precision is in 1 - 2 meter
編制了gps絕對定位中抗差估計程序和應用線性組合進行單點定位的程序。通過對粗差量級的分析,得出在gps觀測量存在粗差時, m估計是有其應用價值的,它使定位結果較為穩定,減弱和剔除了粗差的影響。應用線性組合程序對gps綜合檢定場數據基線網點進行計算,得出用廣播星歷和平滑后的偽距可以給出較好的結果,點位精度在1 ? 2米。Application of linear programming in gross error detection of photogrammetry

運用三維可視化技術使dem的粗差檢測與改正實現了可視化Measurement and characterization of surface texture is an important aspect of precision metrology. historically this has involved partitioning a profile into different wavelength regimes referred to as roughness, waviness and form followed by numerical quantization. parameters computed are then inspected for tolerance compliance to ensure a part performs its intended function. this approach is satisfactory when the specification has been carefully determined and the process is stable. however, when the manufacturing process is under development or when instability or modifications to the process invalidate specifications, there is a need to study surface finish parameters in relation to functional performance or process measures. in this context, the problem of surface texture classification and recognition are discussed. advanced techniques developed for this purpose along with applications are presented. also, the techniques discussed here will be useful across large bandwidth, from the characterization of nano scale to traditional micro scale surfaces
表面結構的測量與特徵描述是精密計量技術的一個重要方面,傳統上包括將輪廓情況根據不同的波長范圍劃分為粗糙度、波紋度和形狀及后續的數字量化.按算得的參數檢查它是否為公差允許,以保證零件執行其指定的功能.當技術特性已經經過仔細確定,並且其過程穩定時,該方法是令人滿意的;但是,當製造過程正在進行中或過程的不穩定、過程變化使技術特性失效時,就需要研究和功能表現及過程評定相關的表面參數.討論了表面結構的分類與識別問題.同時闡述了為此目的而開發的先進技術及其應用.所研究的技術對從納米尺度到傳統的微米尺度的較大帶寬范圍內的表面特徵描述都是有效的This filter is a combination of adaptive ud decomposition kalman filter with quad method. it use quad method to detect and correct the gross errors in observations, use ud decomposition technique to improve computation precision and overcome the instability of filter caused by instability of values, when divergence of kalman filter had been detected, an adaptive filter is employed to adjust the prediction error covariance matrix
該法用擬準檢定法準確地探測和修正量測方程中存在的粗差;用ud分解演算法改進了計算精度,克服了由於數值不穩定帶來濾波的不穩定性;當判斷濾波器發散后,則啟用sage自適應濾波器,調整預測誤差方差,以克服濾波器的發散。In order to make the quad ( quasi - accurate detection of outliers ) more reliable, objective, practicable and convenient to be automated, the authors modified observation order index, gross error determination standard, and unit weighted root mean square ( rms ) correlated to gross error determination standard
摘要為了使擬準檢定法能夠更加可靠、客觀、實用,便於實現自動化,對擬準檢定法進行深入的理論研究和數值試驗的基礎上,對觀測值的排序指標、粗差的判別準則、判別標準中涉及的單位權中誤差等有關實施細則做了適當的改進。The quad method can detect n - m - 1 gross errors in theory, if there exist, ( n is the number of observations, m is the number of unknown parameters ) and its breakdown point is much high, so its application prospect is very broad in many fields. the quad method program is preliminarily designed with matlab language for its powerful matrix function, simple language and friendly interface
擬準檢定法是一種高崩潰污染率的數據檢測方法,理論上,能探測到n - m - 1個粗差(如果存在粗差) ( n為觀測個數, m為待估參數個數) ,因此該方法在許多領域有比較廣闊的應用前景。分享友人
