Recovering Profiles of Roadbed Based on Statistical Scanning Data

P. 194-201.
Bronevich A., Karkishchenko A. N., Umansky V. I.

In the paper the problem of recovering cross profile of roadbed is discussed based on statistical data derived by laser scanning device. The solution of this problem can be got by analyzing statistical sequences and estimating their trends. We propose the method of estimating such trends based on an assumption that statistical sequences can be considered as a piecewise random process, which parametrically depends on the profile form. The estimation procedure is based on evaluating likelihood functions for statistical sequences presented in polar coordinate system.
