      Suvremene mjerne tehnike razvijene temeljem povećanja mogućnosti bezreflektornog mjerenja duljina omogućile su otvaranje novih područja otkrivanja i analize pomaka i deformacija. Prikupljanjem velikog broja točaka često će biti potrebno pronaći matematički model plohe koja se njima najbolje prilagođava. Iako je to za prostorne plohe složen postupak, za ravninske plohe lako se obavlja i omogućava dalju obradu i analizu podataka mjerenja. U radu je prikazano prilagođavanje ravnine skupu mjerenih točaka metodom najmanjih kvadrata udaljenosti, uz prethodno uklanjanje podataka koji znatno odstupaju od zadanoga skupa upotrebom algoritma RANSAC. Temeljem toga prikazana je metoda analize deformacija i pomaka ravninskih ploha.
      Modern methods of measurement developed on the basis of advanced reflectorless distance measurement have paved the way for easier detection and analysis of shift and deformation. A large quantity of collected data points will often require a mathematical model of the surface that fits best into these. Although this can be a complex task, in the case of planar surfaces it is easily done, enabling further processing and analysis of measurement results. The paper describes the fitting of a plane to a set of collected points using the least squares distance, with previously excluded outliers via the RANSAC algorithm. Based on that, a method for analysis of the deformation and shift of planar surfaces is also described.
